The sound quality from these headphones is amazing. I use them at work to completely cut out my co-workers and their noise. I can attest the noise canceling cuts out talking, chewing, phones ringing, coughing, cars going by... they're great.
My only problem with these is the Bluetooth connection. They're literally three feet away from the Bluetooth connection, and still don't always stay connected. I've been using the cord to attach it to my computer instead, and I get crystal clear listening all the time. I don't need them to be wireless, and they DO work wirelessly, but to my computer, they appear to glitch. Paired to my phone, they work fine. But I don't like to use my phone for music when I can stream over a desktop connection.
They're comfy, don't smell like plastic, and don't leave red marks on my fat head. A great set of headphones.
