[This review was collected as part of a promotion.] I had a pair of these before I upgraded to the most recent model and I absolutely loved them. That's why I stayed with Bose. I actually gifted my older model to a friend and it blew their mind how well they performed. I would highly recommend these to anyone who's looking for superior sound quality and noise canceling technology.

The sound is great. I recently purchased these and I am still getting adjusted to putting them on my ears. They are different than other earbuds I have had. I love being able to listen to music and still have contact with the noise in my environment

[This review was collected as part of a promotion.] I bought these earbuds about 5 years ago, and they are still going strong. The only drawback to the design, which may have been fixed in later versions, is that I've a been unable to clean some of the ear wax from the earbuds, and it has caused some rusting over time. The rust has not affected the performance of the earbuds.

[This review was collected as part of a promotion.] I got these refurbished and they are perfect. Since I always wear the Ultra Quiet Comfort on the quiet setting I didn’t know if these would work for me but they have amazing sound. I definitely recommend them!

I purchased this item with the expectation of hearing the quality Bose sound that I have heard for years...that was not the case. I have adjusted the sound and equalizer but unfortunately I still dont hear the perfection that im used to. While the sound is not horrible, its not what im accustomed to hearing from the many Bose earbuds that I own.

[This review was collected as part of a promotion.] I bought these because I kept seeing adds. I was skeptical at first on how they’d fit, feel and sound. I was blown away at how they’d fit feel like on the ear. After a couple of minutes you can’t even tell they’re there. Comfortable enough where you don’t get ear fatigue. And the sound… THE SOUND!! The sound was amazing. You get enough sound coming out but still are able to hear the world. Great purchase.

[This review was collected as part of a promotion.] I love my headphones. But, the sound quality in phone call is very quiet. Hard to hear the other caller and they have complained about not being able to hear me in call. Otherwise overall good sound.

[This review was collected as part of a promotion.] I have purchased a quiet comfort product in the past. I typically buy the Bose products without questioning the product. But I will say that when it comes to the product. I thinks that Bose is behind the competition for what the product offers vs the price point the product costs. I will say that the sound quality is good for the product. However the level of volume and the noise cancellation do not compare well compared to the air pods that I purchased. I also feel that the air pods hear through option is superior to the Bose product. Also the ease of connectivity with my iPhone is more convenient. This is something that I wish Bose could bridge the gap better.

[This review was collected as part of a promotion.] The idea is there but the actual use of it doesn't meet the idea. I bought a pair for my wife and when she calls me I have a hard time hearing her when she uses the open ear buds, it's like she is talking 5 feet away from the phone. She uses an iPhone and I am on a Samsung Galaxy 26 Ultra.

[This review was collected as part of a promotion.] These earbuds are comfortable and the sound is what you would expect from a Bose product. In ear style earphones would never stay in when I worked out. These stay secure and I don’t need to worry about them falling out
