I have given up on TWS for sleeping. I currently use the B&W Px7 S2 for sleeping since I sleep on my back.I tried soooo many TWS for sleeping and while the 1more Comfobuds Z were ok for side sleeping, the battery lasted only 2.5h in the beginning and became less and less rather quickly
Then I realized that for sleeping, I am not too fuzzy about sound quality, since I listen mainly to binaural / meditation / sleep music ... and for that check amazon.fr for musicozy sleep headbands ... I got my first for as low as 10€ ... and I wear it every night now! Battery lasts over 12h, I don't feel anything when laying on the side ... just a thought, I wish I had tried those earlier, would have saved me some TWS money
On separate note, I got the Galaxy Buds2 Pro yesterday and, in my opinion, Samsung did great job with these. I get a nice stable fit with the large stock tips and a good seal and I did not need to adjust nearly as frequently as my Galaxy Buds2. They are a bit larger than my Buds2 but this may be helping with stability in my big ears (I like the new flatter design). Sound is much more balanced although mids/vocals did sound a bit recessed for my taste. It would be nice if Samsung provided a better EQ. SSC codec is nice but I was getting some distortion if I turned on 360 Audio (source was Amazon Music on my Samsung S22+). For the $110 these cost me (after trade in), I am very happy with these.
