These are Bose Sleepbuds II. They were hugely popular, but ultimately discontinued in ‘23 due to battery longevity inconsistencies in the individual buds themselves.

They’re crazy comfortable and the only thing that saved my marriage to a snorer. I couldn’t hear a thing, it was bliss, they’re life changing.

I had 2 sets of these without issues. I was so upset when they were discontinued I bought these ones as a backup for when mine eventually “end of lifed”.

However when I got these out to use after a few years of being unopened in a safe dry place, I found the charging case was out of battery, and it wasn’t recharging. I googled it and it’s possible to fix this issue and charge the case, but I don’t have the know-how or the tools to do it myself.

RRP was $479 NZ 2 years ago. If you can get these going you’ll have a bargain. Reddit is a good place for instructions on charging the case.
