In case anyone is looking for a better aptx adaptive dongle for the Momentum 4:
The Creative BT-W5 ended up developing skips and crackles when using with the PS5. I ended up buying the Ugreen CM668 which, by itself as less issues, but to really fix it, I had to use a USB-A to USB-C adaptor with it (to connect to the USB-C port on my PS5). Seems like this setup removes every skip and crackle in the sound.
On my PC, no port causes crackling, so it's weird.
The KB8P works ok, but the sound is noticeably worse than the alternatives. (I have a few songs where it goes into the lower frequencies, for some reason this dongle seems to cut them, or make them prominent).
The Avantree DG60P, at first glance sounds fine, but
using this tool you can find some weird sound distortion.
Never bought the Sennheiser's official one since that doesn't work properly with the PS5 (it forces the headphones to have the mic always on, which makes the sound worse).
Wish I could use the BT-W5, it seems to me that a sound is, perhaps, a bit better than the Ugreen CM668, but it could be placebo.
Everything I've said here is about the low latency modes, the high quality modes are useless to me.
