I bought a pair. Price is decent.

I'm interested to see what this Tensor A1 can do. If it can provide significantly better call quality to those listening to me while I'm in noisey environments, I'm happy to upgrade. This seems like a place where there should be some very good machine learning wins possible, and I think Google has people who could pull it off.

It also advertises as having Bluetooth LE (which I take to be equivalent to marketing speak name BT Auracast), which I hope starts to arrive soon. Im more interested in its use on speakers, but I love the idea of ambient listening experiences all around us that we can tune into or share ourselves.

> the Tensor A1 chip runs 90 times faster than the speed of sound

Finally, a chip that runs at thirty one thousand meters per second

Yes, I wondered what that was supposed to convey! I thought perhaps it was 90 times the sampling rate (96000 per sec), but that would be about 8mhz, which is not fast at all, or maybe it is for an ear bud?

My guess is it's the speed with which the microphone picks up a signal, the chip processes it, and updates the noise-canceling waveform on the speaker?

So that's the time, and the distance is between microphone and speaker, so it can be compared to the speed of sound.

No idea if that's plausible or even what they actually meant though.

Pretty sure its this considering the next bullet says the same thing "Active Noise Cancellation with Silent Seal™ 2.0 adapts to your environment 3 million times per second and cancels up to twice as much noise."

We're going to assume it means:

    - 90 calculations per the distance traveled from mic to speaker

They also mention:

    - 3 million calculations/second

Canceling out the calculation unit, that comes out to 33333 Mic-to-Speaker-Distances/second.

We know:

   - Speed of sound is 343 m/s.

That puts the Mic-to-Speaker-Distance at a bit over a centimeter.... that checks out.

The engineer-driven Google of old is truly dead.

Lmk when we have FTL capible earbuds

I’ve had 3 pairs of Apple Airpods. All three of them eventually had problems with charging. One bud would be full charge and the other empty. Sometimes I’d put them in the case and the light indicates they are charging but come back later and they didn’t charge at all.

Does Google’s pods suffer the same issue?

Is this common? Asking because I went through multiple pairs of airpods (due to upgrades and just straight up losing a pair), and I’ve never encountered such an issue (and none of my friends encountered it either).

I had a problem occur like once every year or two where one airpod just refuses to work, but a quick unpair/pair cycle solves it.

It’s common enough that there are posts about this issue if you do a search for it.

Given the insane sales numbers of airpods and their prevalence, I am not surprised there are some people who would have it. Given large enough userbase for a product, someone is bound to have an issue like that.

I am just curious how prevalent it actually is in terms of a bit more hard numbers. Not asking you to produce those numbers, because I doubt they are actually available. I am just mostly wondering outloud.

I wonder too and I think it’s below the number of users with issues with the butterfly keyboard but much higher than a trivial percentage.

I haven't had this issue with my Pixel Buds Pro over the last 2 years. They hold their charge surprisingly well.

Thanks for the feedback.

I was seeing the same with my Pixel Buds. I've started to give them a little extra nudge when I put them back in the case and that has seemed to eliminated the issue for me.

I’ve had to move around my airpods to get them to charge but often times when i close the case they stop charging. I will never again Apple headphones.

silicon buds are not comfortable to my ears.
