Bluetooth is terrible. My gripes are:
1. Re-connect from mobile to desktop takes minutes.
2. Batteries need to be charged (and are always not charged when it matters)
The AirPods are the only product in the same class that can sort of link to more than 2 devices... but all of them need to be apple.
Now I use it exclusively on my phone for music and I have another headset for voice calls on my computer. Which is a shame given how much money I had to throw to buy this thing.
Still, I have to acknowledge, sound is awesome, so that’s why I keep it anyway.
Also does dual connectivity even work with LDAC? I feel like the best way is to use software to connect manually. You do have to specify the address and such, and execute the action, and you have to disable Bluetooth when you don't use it. Advantages are less tracking and interference.
As for XM5 it is expensive compared to XM3 and XM4. If you want to spend that extra money there are better targets (victims of current war for example).
