2024 I finally tried some Bluetooth headphones after maybe 10+ years.
Still using SBC by default, still no duplex HD audio, and still static driver noise at idle.
What is even the point lol. SBC-XQ only solves the first problem which is still inferior to even the cheapest of quality 3.5mm cable.
Even my Nintendo DS sounds better and it's limited to 32Khz audio lol.
