Chosen Solution

My Bose SoundSport earbuds are about 18 months old, and I’ve noticed the battery performance is decreasing. These are $120 headphones. Is it possible to remove the housing and replace the battery?

I was able to find battery replacement parts for them on ebay. It appears that the battery is soldered to the board inside so if you are comfortable soldering you should have no trouble. I couldnt locate a teardown guide on here but youtube has a video doing exactly this. https://www.youtube.com/watch?v=W_scZh_c… the parts on ebay were around $20. Good luck.
