The sound quality is exceptional, although I don't hear a significant difference from a pair of QC earbuds that I own. However, the cushion over the unbreathable earcup is unbearably hot and humid after a couple hours of constant use. It was 32 degrees outside in the winter and my ears are hot and sweat! I cannot imagine myself wearing a pair of these in the summer at all. Also, it does not have adjustable levels of noise cancellation like the earbuds do.

These head phones are the comfiest things to wear. I previously owned a pair of Beats Solo headphones and want to upgrade to an around the ear as opposed to the on ear Solo's. I went and bought the Beats Studio 3 and I did not feel like I got an upgrade. The quality was not there at all. I felt like I got ripped off. This Studio 3's and the Bose QC45's and pretty much the same price. I am so happy I switched to Bose!!!

They seemed quite expensive, but I decided that I was worth it. The dryer was going when I put them on. I could not hear the dryer so I was concerned that something was wrong. I took them off and then heard the dryer. Noise cancelling does work. All in all...a very wise purchase.

Unfortunately - they stopped cancelling noise! There's a difference between quiet and aware mode, but the quiet mode doesn't work nearly as well as it used to. The microphone also stopped working almost entirely, it seems to only pick up about 10% volume, which is possibly why the noise cancelling feature stopped working.

Bought these headphones because the brand and price….but they would always lose connection when my phone was on my hip, and almost every other song 🎧 would lose the connection….felt great on, but frustrating to lose connection… Going to return them, and hopefully I can swap them for a new pair, and maybe they will stay connected 👍🏻

A great Bose product at a super discount price! I couldn't pass this up! Thanks BOSE!

Amazing! Had them for two years and I love them. Amazing purchase.

All my audio devices are Bose , they also make great Christmas gifts .

Works perfect with both my iPhone and my computer and you can wear it all day long

I bought these headphones about a month ago and they have fulfilled all my desires for headphones
