The QC Ultra line support AptX adaptive which have both a high quality and low latency mode. The issue is, AptX had a branding problem. For example, my Samsung S22 Ultra has AptX but it will not use AptX to my QC Ultra. Why? Because the transmitting device needs to support AptX adaptive specifically. The older versions will not work. I don’t think Linux has cracked the AptX adaptive codec yet so the Steam Deck won’t transmit. There are external dongles that will do AptX adaptive, like the Creative BT-W5.
I dont think these will work.
