I'm having an issue with my S20 where all new bluetooth over-ear headphones have really poor quality.
I've tested out every brand I could find - Sony, Bose, Sennheiser, etc. I've followed all the troubleshooting guides I could find on the internet (switching to LDAC, various developer settings adjustments, using the headphones dedicated app to change EQ and settings, etc) and still no change. Usually the bass is pretty decent, but the sound is very tinny in every brand and model that I've tried. Changing the EQ doesn't do much to improve it in any case either.
I tried the same pair of Sony WH-1000XM5 headphones on my S20 and an iPhone X, and the sound from the iPhone X was noticeably better than the S20. I have no issue with my existing bluetooth products - Jabra 65t earbuds and Sony SRS-XB23 bluetooth speaker.
I'm desperate to have a pair of over-ear headphones for long-distance travelling. Is there anything I can do? I feel like I've searched everywhere for an answer!
