thanks, that sounds pretty standard until "new" 5.2 low-latency stuff hits the market / replaces the current chips.

> I usually plug them into an Anker SoundSync, which costs more than the headphones themselves, but they have the best Bluetooth, battery life, and DAC of any wireless dongle I've tried.

using them on a Windows PC: Have you tried watching video content (lip-sync) / play games with the SoundSync?

I really want to try those (or the sender/receiver version) to have a universal BT<->3.5mm dongle.
