Pros:
- The dongle connection is actually low latency as advertised (but bluetooth is still slow)
- The output sound quality is very good, probably above Sony WF-1000XM3 and Samsung Galaxy Buds Live
Cons:
- The earbuds being able to do Bluetooth and dongle audio simultaneously is a lie. One mutes or even disconnects the other
- The mic quality is bad, not great for any calls or voip
- Can't get the mics to work over the dongle
- Bluetooth stops working and it takes putting the earphones back in the case to get them to work again.
- Generally the reliability of the headphones makes them hard to use, I often go with technically worse headphones, cause these are just too much hustle, whether I want to listen to some music, take some calls, or even play some games.
I'm on firmware version 11.56 the newest available 2022-11-06. Hope they can fix the issues with an update, but that is very iffy. As it stands now I think you should avoid this product unless you must have dongled low latency wireless headset without a microphone, and can live with constant outages (hard to imagine a use case for that though - if your a gamer you don't want to loose the sound in the most critical moment, if not low latency will not be critical enough to sacrifice convenience to such a degree)
