They fixed some/most of the issues. Bluetooth connection is so poor on the two units i had that i wouldn't recommend them to anyone though.

I have issues with anc or anr in my left earbud. Sometimes it randomly starts putting out way too much pressure and making really weird noises. No idea what causes it, but it's really unpleasant.

Unfortunately it only shows a setting for aptx adaptive, seems like the grell are not being recognized for having lhdc by my phone.

I wonder if users are aware that you can increase volume on your phone and on your tws1 by swiping up right? If both are maxed out, the Grell play pretty loud for me. So far i like the sound a lot, pretty much what i look for in a tws iem. I'm on Android 11 (oppo find x2 pro) and my phone...

This would not improve the audio quality and is pretty pointless. Bluetooth iems will do the digital to analogue conversion, so all a Bluetooth dac paired with bluetooth iems would do, is at best create worst latency.

Gapless works fine except when playing in shuffle mode.

Anyone tried to change the package name of an apk file that isn't whitelisted to one that is whitelisted to get around the whitelist?
