Do I need to get out the soldering iron again? (2018)

Yes, these devices are needed, because the audio outputs of all sorts of devices today simply are trash.
Topping DX3 Pro+[0] is my current recommendation, by the way.
As for headphones, Sennheiser HD600 really are solid.
0. https://www.audiosciencereview.com/forum/index.php?threads/t...
Of course, I'm not saying it isn't worth it at all. That depends on one's budget and ears. But most lists see the expensive option as the best, while most peoples needs and ears have zero use for the expensive option.
I'd go so far as saying you could get 95% of the way for 10% of the price.
- one high quality capacitor: $1
- knowing where to put it: $799
[dark timeline: “knowing it doesn't matter where you put it: $12999”]Do some research first for your use case, but I suspect one can find one that will work for your machine + headphones.
Soundguys has a review from October up on this topic: https://www.soundguys.com/best-usb-c-headphone-adapter-10130...
It compares favorably against equipment hundreds of dollars more (focus on SINAD & Output Impedance graphs): https://www.audiosciencereview.com/forum/index.php?threads/r...
Admittedly this calculus may have shifted in Apple's favor a bit when they rolled out their own silicon.
I admit, I was one of these people, but when you look at incidentals (ironically the DAC such as this thread, but also things like keyboard, calibrated display, the nebulous concept of “build quality”) Apple is comparable in price to contemporaries.
The issue is that Apple computers are built like higher end business laptops, and people dont typically buy those: they look at the spec sheet and try to buy the best bang for the buck which makes all of the quality run out the door.
Apples lowest end machines generally are priced cheaper than equivalent machines, but Apple price segments (read: gouges) on upgrades.
A high end Macbook pro 14” and a Dell XPS (55xx) are comparable in price.
(I never had a charger or touchscreen break on me before, nor a battery wear so fast, so combined with the unusually low use, I'm pretty sure it's not my particular usage pattern that caused them to break way before due.)
Credits where they're due, though: it had a headphone jack and I loved the earphones that came with it! But what a piece of trash otherwise.
I'm sure there's good apple phones out there and our resident apple fanboy assured me I had an outlier, but I can attest that apple does in fact sell you garbage and not all the issues are hardware
If we look at the low-end, it is much worse: the cheapest Macbook Pro ($1600) gets 12CPUMark/$, while the Dell Inspiron 15 3535 ($420) gets 45CPUMark/$.
I know there's much more to laptops than their CPUs, but I think my point is still valid.
But really what I don't understand is how Apple can't just add an option to turn off the damn accessibility options entirely. Why does dirt or temporary bad connections cause this problem at all? They could just let you turn off the setting that it triggers so that it really doesn't matter. The fact that they don't care enough to do that tells me enough of how much they care about making their headphone adapter a good product. I never used to have to worry about issues like this with a regular headphone jack, but I certainly do with Apple's adapter. It's simply a poor product.
Although I must admit I did not expect the Apple USB-C to 3.5mm adapter to be so affordable. I don't have any Apple devices but I wonder if will work with Android/Linux.
> There is absolutely no reason at all to pay more for a USB DAC, at least when it comes to pure sound quality with headphones.
It does mention the possible desire for more features, of course. And it's possibly worth mentioning the power output is half of what you get from other DACs, but you should consider whether that means anything to your setup. I have a pair of Hifiman Edition XS connected to a Schiit Magni and the Apple USB C DAC, and I never put the Schiit volume above about 30%.
(As to the amp: I do hear a bit of an improvement connected to the amp vs just the DAC. It's not huge, though; mainly I like having a physical volume knob.)

This device is actually a gem for the price, and most popular recommendations will go higher in price and give you less. I have been there and done the digging, you're welcome to repeat the process.
At some point, new devices or new prices will change this. But, as far as I am aware, this is how it is right now.
If there's any money left, it can be allocated to a dac/amp combo, but priority to headphones, as they matter the most.
* USB soundcards used to work on Android but in recent tests they failed again for some reason
* Avoid any dongle that supports "special effects", "gaming", etc. Even if they can be disabled, it's such a pain.
* Dynamically adding/removing soundcards can affect your computer's notion of "default microphone", particularly relevant for video chat. Some apps this takes effect immediately, some after quitting the app.
Works out of box in ubuntu, this is how I use it: https://files.catbox.moe/755gbr.jpg
The four-pin versions (with mic input) tend to fall down pretty hard, though. Either the volume is so low you have to yell to get anything into the PC at all, or there is severe cross-talk where any audio coming out gets induced into the input. (Turns out people on zoom are not fans of hearing echo of themselves with a 1-second delay!)

The iPod basically couldn't output bass because their dac couldn't maintain anything close to a square wave. (There used to be online comparisons of this thing with the iPod, similar to what you linked.)
However, that was 20 years ago, and it hit -95db of hiss, 20-20khz frequency response, with way more power than is needed for in-ear monitors (which is my use case). Apple ended up shipping an iPod with a non-terrible DAC the next year (I think the touch was the first one? Can't remember).
Anyway, now you kind of have to go off the beaten path to find consumer stuff that's perceptibly worse than ideal. In particular, you can get a USB-C -> headphone dongle from apple that's actually a decent DAC for $9 (look at the THD graph. They use the $9 Apple as the cutoff between "yellow" and "green"):

These days, if you're getting noticeably bad performance out of your laptop DAC, it's probably a shielding or grounding issue. The standalone USB DAC will fix that, but only if it's externally powered + grounded (or if you get lucky with how your laptop is wired / shielded), but so would bluetooth (which even supports lossless audio as of 2021).
A usb/bluetooth dac for my laptop/phone (standard phone usb-3.5mm adapter's not powerful enough either) and a toslink dac for my desktop solved all my problems. Toslink's an awesome nuclear option to buzz/noise because it's 100% isolated by virtue of being light.
I also enjoy being able to boost the bass/mess with the EQ easily.
Isn't the defining characteristic of a square wave the fact accurate reproduction of it requires the ability to produce high frequencies? Why would that be particularly problematic for bass?
I currently use a Hel day to day:
https://www.schiit.com/products/hel-plus
Lets me do work meetings with headphone+mic on one system via USB, or switch and listen to PCM audio via second input
If portable isn't needed, about the same money buys that topping, with digital encoder for volume, higher specs and better measurements... but no mic input.
As a staunch objectivist audiophile, I empathise with this view. But there's also too much of an obsession with achieving levels of dynamic range precision far in excess of the best audio recordings. Not to mention far in excess of the best human ears — let alone the typical ears of an audiophile with time and cash to burn. Perhaps most damning of all, being far, far, far, far far in excess of the noise floor of most people's listening environments.
So long as your DAC/amp gives you a solid 100 dB of dynamic range, it's time to put down your wallet and enjoy the content.
The author paid a significant tax, as documented in their blog post: they had to try several devices and eventually *build custom hardware* to do something so simple. Yes, it’s fun. Yes, it gets the job done. No, I don’t want to do that when I just wanna listen to music.
The apple tax is more than just easy access to music played through marginally higher quality DACs. It’s also a cost that I’m happy to pay to never have to do something like what the author of this article did.
My time is significantly more valuable to me than ideological objections to working technology.
The extremely minor inconvenience of finding a different adblocker is one time pain. Attempting to curate the “perfect” computing environment is pain that just doesn’t go away.
I ran many different distros. I ran LFS as my daily driver for several years. I played with all of the desktop environments. What did it get me? Nothing. There is no practical value in sinking the time into that. It’s fun, sure. But I don’t get paid to have fun. My business doesn’t run on fun.
The ad blocker thing one tiny example; what I actually want to run is Real(tm) Firefox and its rich extension ecosystem. There are dozens of little accessibility enhancements I run on top of just the content blocker. The iOS versions of Firefox are heavily gimped, aren't allowed to run the Gecko rendering engine (purely because Apple said so) and can't do the things I need. My iPad basically doesn't have a good browser, just a cheap plastic imitation of the Amulet of Mozilla. All of my other devices do, so it's the odd one out.
It's not just Firefox, but that's the example everyone's heard of, so it's what I tend to lead with. I'd also like to be able to run weird media software, background file syncing services that aren't iCloud, and (gasp!) retro game emulators on the devices I own. All disallowed by app store policy, and unlike Android which supports sideloading and alternate app stores, on iOS I have no recourse as an end user. So I choose not to be an end user; I won't purchase hardware that refuses to respect my wishes.
There are a couple of things you might want to be aware of though:
* AltStore exists and works pretty well: https://altstore.io
* iOS 17.2 allows users in some locales to side load apps: https://medium.com/@rmndrathna4/ios-17-2-sideload-apps-what-... . This was sparked by the Digital Markets Act, which could also force Apple to allow alternate browser engines. It went into effect May 2023, but I'm not a lawyer and idk how this will actually affect the Apple ecosystem. https://en.wikipedia.org/wiki/Digital_Markets_Act
One of the most classic examples was Copy/Paste or Apps. I remember so many Apple users telling me that Copy/Paste was unnecessary on an iPhone or that WebApps were good enough (something I completely disagreed with) only to see them change their tune completely once Apple released those functionalities.
I remember how 5G was supposed to be an albatross of a feature until Apple released their phones supporting 5G.
Or how digital pens weren’t needed at all, until Apple released an iPad with a digital pen and then it was just raves about how digital pens are awesome.
How can one forget larger screens! I remember how 3.5” was THE perfect phone screen size and now you can’t even buy a phone that size from Apple.
Multitasking!
I’ve tried switching to Android but never been successful. I simply don’t like it and enjoy iOS too much. That doesn’t mean I need to be blind to all the missing iOS functionality and pretend my I wouldnt be happier if they weren’t missing. I just find that the upsides are more than worth the downsides. That doesn’t mean I need to pretend those downsides don’t exist.
Isn't that normally the case? You have a device that does X you're happy with, and they add a new feature. You didn't know how useful it would be, so you're excited and show it off.
I'd imagine there are plenty of examples of his with Android, or your favourite car brand or all sorts of things.

It's well built, sturdy, battery life is great and sound quality very good.
But...
After some use it appears crystal clear that they cobbled together parts without testing them properly, which is normal in cheap devices with no or minimal quality control. FM radio audio level is completely different from recorded music, and at minimum level (that is, 1) it is still too loud for relaxed listening in environment without loud ambient noise, and if you go from say mp3 to FM without adjusting levels be prepared to jump. Touchscreen is badly arranged: some functions are in the way (playing speed to name one) and could be activated by mistake when changing tracks. Navigation can be tedious in crowded directories because advancing by pages doesn't work as it should. Last but not least, as with many other cheap players, the preset based equalizer is a joke. That is not how a proper equalizer should work; just give me a damn graphic one but please stop that useless Jazz-Rock-Classic-Disco-etc. thing that never, ever works. Etc.
That device could have been a real gem if only they didn't ruin it with junk firmware with no way to upgrade it. Had they sent a couple free devices to the Rockbox folks plus enough technical information on the employed hardware, they would now have a real gem instead of a half assed mediocre toy.
For reference: https://www.rockbox.org/
A device like the Fiio Btr3k makes it possible to use good quality wired headphones with one of those modern smartphones without an audio jack. (And it sounds better than the devices that did have an audio jack.)
Oh, and Fiio also builds some nice IEMs :)
Or get everything from Sony which supports LDAC 990k on both the audio sending and receiving sides of Bluetooth. I love my Walkman!
I also have non-LDAC "neckphones" to carry around: the Beyerdynamic "BLUE BYRD" gen2 are far more practical than Sony or Apple earbuds for one simple reason: you can't lose one since in the neckphone format, the earbuds hang around your neck with a cable (which also provides convenient buttons)
Originally, I got the Beyerdynamic for my Chinese eink device (which don't support LDAC anyway) but it's so practical I use it's now paired with my Walkman and computer too!
Neckphones are not easy to find in the lineup of popular brands, but I've heard great things about the latest Huawei Freelace Pro: it's the same neckphone design, but with magnets on the back of the earbuds and ANC.
I'm getting the Freelace Pro "soon" (3 days from now lol) to see if it's more comfortable than my Beyerdynamics

I use an ifi GO Link (~60), with USB Audio Player Pro (UAPP).
The difference between that and just plugging into the 3.5mm jack on the phone is night and day.
There are obviously much nicer and more expensive DACs, but IMO you're hitting diminishing returns quickly.
The ONE thing I hate about going this route is that USB-C is not nearly as robust a connector as 3.5mm. Even the slightest jiggle can cause the DAC to disconnect, leading to a lot of annoyance because Android requires you to re-confirm every time. Some days it's flawless, other times I have to go through the stupid prompts like 10x in a couple minutes.
I would ask you to try for yourself though.
>>> The best way I can describe the Topping compared to the NAD is that the sound is richer and "warmer" (I realize this may sound strange). Listening to music through the NAD for a while got tiremsome or fatiguing. I don't get this with the Topping.

For LFE playback (I.e. subwoofers), absolutely. Use it aggressively. I prefer class G/H topology for my LFE though. I run class AB for my mids & highs.
So far there are 3 of these setups in my house.
For so long I’ve avoided emulating games because something was always fucky about it. Visuals, audio, game bugs — you name it.
I recently bought a Steam Deck and outfitted it with retroarch to see if anything had changed in that world and my god everything has changed. The device effortlessly emulated games all the way up to the switch generation and they look and play beautifully. No configuration needed. It’s the experience I’ve always dreamt of with emulation and it’s a total game changer when it comes to my nerves.
I have an FM radio in almost every room, and a vinyl record player in the living room. This has been (roughly) the state of those two technologies since the 70s. They're simple to reason about and operate.
I also have an extensive digital music collection. And I want to listen to that from...
1. My stereo - so I have Kodi Media Center running on a home theater PC. I control it with my phone. It gets media off my NAS, which means I have to run a backup from my laptop, where I download the music, to be able to listen to it there.
2. My car - which can take a USB flash drive, but can't play back FLAC files, which is how I store them locally. So I have a script which converts them all to MP3s. I need to walk to the flash drive inside, connect it, run the script, then walk it back out.
3. My phone - at least that's click-and-drag.
Listening to a personal music collection has almost definitely gotten more logistically challenging than shuffling around some LPs or CDs, but there are also many more use cases enabled today.
They mention it buffers with a gain factor of 0.1, but I don’t understand how the four op-amps play together to eliminate the hiss.
Slightly off-topic, someone pointed out that MAX232 chips make a great power supply for op-amp circuits like this (using charge-pump capacitors) one because they can hand you +/- 9V from a 5V source (which could be a USB power brick). I'm not sure but I would guess that the current needs of his audio filter would be within what the MAX232 could handle.
I made a small PCB based on that idea for experimenting with op-amp circuits on a bread board.
I'm not entirely sure, but it appears that this is setup to amplify the ground noise.
I'm also not entirely sure why you would want a gain of 0.1, you would probably want to preserve as much amplitude information as possible.
Also the power circuit on the left shows a resistor ladder with 9V over a 1k resistor on one side, and the same for the other. 9 / 1000 = 9mA, x2 is 18mA. Added with the amplification of noise, I can see where 25mA may come from.
> Yeah, and two op-amps for the ground filter has me stymied as well.
I think this is because it's the ground for both the left and right channels, which is potentially two op-amps worth of power and you don't want this dumped through the headphone jack.
I haven't tested this, but would probably go for a simpler design like this:
https://www.falstad.com/circuit/circuitjs.html?ctz=CQAgjCAMB...
I’m not sure that it’s really necessary here with modern op amps, and the author may have just copy-pasted the circuit from somewhere.
I can't see how this could reduce 'hiss' if it there's something wrong in the first place,all seems very unlikely though. Possibly it eliminates hum (which mobile devices are generally hideous for, when charging) but the details are likely to be setup-dependent. Or maybe RF is leaking out of the phone causing the hiss in those particular headphones, and all this is doing is stopping that.
Not sure though.
I don't understand why this circuit needs an artificial ground at all, since the power source is two 9-volt batteries in series. AFAIK that could make a dead-simple bipolar power source +/- 9 volts and get rid of about half the parts.
The 10:1 voltage divider is also an interesting concept. It seems to me that what this thing does is attenuate the input signal and then provide a low impedance output to drive the 'phones. I wonder if the writer ever considered something as simple as shunt resistors.
Perhaps a "real EE" can enlighten me.
FWIW, I use a AudioEngine D1 USB DAC to drive headphones from a computer. It was not cheap, but neither is my time. For portable use I am rocking (with RockBox) a old iPod "video" with aftermarket SD card mod.
The other two each drive one channel. The 0.1 gain is to reduce noise created by the DAC, which is independent (in this case) of the volume control. So the author is turning up the volume on his device, to compensate for the 0.1x gain. Accordingly, DAC noise at the speakers is 1/10th what is was before, but the signal is the same.
Thank you! This is the first explanation that made sense to me.
Hiss is reduced because of the attenuation.
It's quite possible a simple resistive pad would be equally effective as the whole thing.
The weird topology voltage divider attenuates the signal. the op-amps buffer the output. The 470R resistors do nothing. The 1k/1k virtual ground does nothing.
The rest of the authors writings smell of /r/iamverysmart
In case anyone else runs into something similar: make sure you've plugged in the headphones to a speaker/HP jack instead of "line out", or configured the output as such, since the latter is unamplified and can make the audio sound "thin" and lacking.
(On the other hand, I've had to do the opposite with some very sensitive IEMs where otherwise even the lowest volume setting would be almost painfully loud.)
There is at least one which doesn't - USB Audio Player Pro can drive a USB DAC and some phones' internal DACs directly:

> My desktop has great sound quality but I don't want to be sitting at my computer chair while I listen to my music, I do that too much already.
Perhaps an extension lead would have been a simpler solution here.
Using Chrome on Android and also on my computer, the annoying pop does thankfully not appear between music tracks with my Simple Music Player, called JUkebox with Php and Html5, short JUPH: https://github.com/quimoniz/juph
I tried to make it dead simple, using the HTML5 Audio element.
Now it's been lying around for 4 years... does anyone else know of a similarly non-sophisticated audio player?
I've experienced this too, with certain audio hardware, on my Windows system. It appears that the system is connecting and disconnecting the audio hardware without muting it. It's not a matter of improving audio quality, but of removing some sort of glitch that's happening.

There was a time when I'd laugh, but in the recent years Apple Music has been doing random crap like that on Mac, iPhone, even HomePods. I'm one subscription price hike away from switching back to BitTorrent.

Unless you're running Replicant - no, it isn't.
I bought the Apogee Groove recently and I can't imagine ever needing to upgrade. It has the same chip that you will find in $1000+ units.

Ah, the wailing cry of an inverse fanboy. Like the fanboy, but with extra dollop of smug and righteousness.
I’d estimate that 99% of people don’t know how their phone works, and I’d further wager that there’s no strong correlation between such knowledge and the operating system of their phone.
My Macs, iPods and iPhone's audio outputs always rivaled my Hi-Fi amp's (an Akai AM-2850) and desktop sound card's (an ASUS Xonar D2X) without any extra equipment.
So, while Apple devices are expensive, they don't skimp on such things. Instead they silently pack an entry level high-end Hi-Fi subsystem inside and be done with it.
Or you can get a Sony Hi-Res media/music player.
You can also rely on the fantastic quality of the Apple USB-C to 3.5mm adapters [0] as "Neutral, clear, clean and very precise. Basically as audibly transparent, good-sounding and clean-sounding to my ears as a device could be...".

I think I saw someone on HN say that strong opinions are generally a sign of lower intelligence as there is a lack of consideration of both sides of the argument. I realise this comment now reads like copypasta but there is a lot more nuance than "Hurrdurr I don't want to be a mainstream normie Apple bad!".
(Ignoring the all caps) That's not really apple bad as an argument. It's the fact that you're paying more for music you probably already own, and you have zero idea how that phone actually works.
Tinkering with technology, whatever the reason, should be encouraged?
If I had to understand how everything worked in my life before I could use it I would die. How does my gut convert nutrients in my food?!
“Although Android is Free Software, meaning I can modify the code, it would probably take me months to learn enough about music decoding and the Android-media-player-service to write a fix.”
Like, mate. You also have no idea how your phone works despite being fully capable of finding out and even having a motive to do so. (That’s what I would say to the author.)
I want to install a binary without a dozen security hoops I can't turn off.
I don't want my local documents being scanned for whatever Apple caved to some government about this year.
I want to own the private keys to the hardware I buy, not a company who can lock me out if they feel like it.
I want to buy third party components, without needing them to be crypto locked to my machine or needing to get corporate approval. again if they feel like it and they're having a good quarter.
I don't want to be forced to discard perfectly working hardware when Apple decides to stop supporting it.
In short, they really, really hate the idea of you owning something they don't control from the atomic level to the cloud.
