arguably my best investment. i bought these two years ago and they still work practically as good as new. battery life is still amazing, with around 24 hours of listening on a single charge. noise cancellation is excellent, especially on quiet mode. very comfortable, and i have small ears so some headphones hurt after time but not these. sound quality is superb, but has slightly declined over time. the only other issue is that it gets staticky on occasion, but it doesn't last very long and doesn't happen often. amazing headphones and extremely worth the price.

I've had a number of Bose headphones, and they seem to continually degrade in quality. Sound is still great, but connectivity is unreliable, durability is noticeably worse (particularly in the muffs) and I found better quality noise cancelling in other brands. Huge fan of Bose, I think they just need to return more focus to quality.

Upgraded from the 35s. Regretted it ever since. I've had constant connectivity issues where the headphones just cut out. Even the headphones are not paired with any other devices, i still get drops. And I am sitting right next to my phone, trying to listen to music. I never had this issue with my 35s. I'm bummed and likely won't buy another set.

It's an excellent buy at a very good price (on sale)… Hope it lasts a very long time.

Enjoy them very much. Got a good deal too.
