They are great.

I've had these for a few weeks now and so far am liking them a lot. As per other reviews wife says the mic isn't the best quality sound although not horrible either. Connectivity is easy and can use each bud independently, a must for me. I've got super small ear canals and lobe so I was very concerned with comfort/pain over time and them staying put during movement, other buds would fall out with something as simple as a smile. Over all this far I can wear them continuously for 4hrs with minimal discomfort, I give it a 3.9/5. Again stupid small ears. They stay put very well although don't waste your money on the stay in place accessories are hey make it worse, wasted $9. Last but not least the ANC function. There are 3 off, on, and aware. Off is normal sound obstructed by something in your ear, on is “oh my where did the world go” (I use mine in an industrial construction environment so yeah wow), and aware u can barely hear what your listening too doubt I'll be using that much. All in all I'd recommend them.

What a software disaster! Can’t turn off the voice prompt that talks EVERY time you put them in your ear - “Battery level 80%, Voice Commands On.” Seriously? Let me turn that junk off!!! Oh, and it autoplays every time you put them in your ear, and guess what? Yep, can’t turn that off either! The touch controls are too sensitive - don’t bother trying to adjust the fit. You’ll only Jack with every control there is. What a lousy design. Man BOSE is such a pale shadow of who they used to be!

I am so happy with the product they're very affordable and the quality is excellent

These earbuds work well, but they are not easy to pair. I had great difficulty pairing them with my iPhone.

I purchased the Quiet Comfort ear buds for the noise cancellation feature as well as the comfort. It was a great decision.

Had a pair for a long time, they stopped working but liked them so much bought another pair

Fabulous sound as expected from Bose! Love the battery life as well and I'm amazed at how well the noise cancellation works.

I absolve these. They are comfortable, compact, and the SOUND is beyond great! The noise cancelling feature is unbelievable.

I have 2 QC Ear buds and they're great. I didn't think it could get better, but WOW !
