These are the best ear buds I’ve experienced
Noise canceling is unbelievable
Sound is incredible
Worth every penny.

Went through 3 pairs in less than six months. They sound great, but fail very, very often. Especially renewed headphones from Amazon. It feels like all Amazon does is clean and resell the headphones without doing any functionality testing or fixing the reason people return them.
I'm still trying to get a pair that actually works, because the ANC is still top notch.

Items provide very good sounds at all times.

Bose quality is really good, but still overpriced and overrated!

After having these for about a year, the sound is excellent and the noise-cancellation is great. Unfortunately, these headphones have some flaws from a user-experience point of view. I'm technical and mechanical, so I can live with these, but others my not:
– The top half broke off due to the very thin hinge and no way to stop the top from slamming when closing it. A little JB Weld and it's back together along with some thin felt tape to soften the blow of closing.
– There is a small removable rubber ring that sits in the middle of the earbud. This comes off very easy with the slightest roll of the finger. I've found mine on the ground twice.
– If you do not place the middle ring exactly in it's place and rotated exactly where it needs to be, it will not charge when placed in the case.

The renewed are not worth the money. They supposed to be excellent but they are not. Maybe new these are worth 150-200 MAYBE and renewed they would be a value to me at 100. I’m using that metric based on having 8 sets of medium to high end headphones. I’ll keep a week and see if they grow on me then I’ll return if they do not. I’ll update review then.

Simply put, these are the best in-ear bluetooth phones I have. I know that for some people they sound too bass-heavy but that's exactly what I was looking for. Sony and Sennheiser are more natural but I like my music punchy.
In calls they are just as perfect.
Connection stability is supreme, control are very easy because the touch zone covers the whole earbud.
Comfy and not jotting out like Sony's or Jabra's. Running on treadmill at 11 speed and no tilt.
Immersive mode is brilliant. Noise canceling is the best I've ever seen. My desktop computer sounds like a Boeing Jet when I do renders or post production but as soon as I put on my Bose's, all is calm and quiet. In "aware" mode, I can still clearly hear outside world with a lowered volume and listen to my music to my heart's desire. I used aware mode in my band practice jam sessions and I can clearly distinguish and hear both the track in my ears and my own drum playing.
That said, if you are looking for in-ear monitors, go for Shure. Like I said these are pretty bass-heavy so you won't be hearing your songs as others probably will.

Right earbud does not work and return process is not easy
