The first thing I noticed with the headphones is the comfortable fit. I wear glasses. The ear pads don’t put pressure on my ears like other over the ear headphones I have used in the past. The sound quality is great. The stereo separation is noticeable and the treble and base are balanced. When used with my cell phone the conversation is clear and the person I am talking to has no problem understanding what I am saying. As for the noise cancelation. The ambient background noise is reduced allowing for clear reception. But you are still able to hear what is around you. The battery seems to last forever. It is nice that vendors are moving away from th the mini USB to the type C connectors. I do not have any negative comments. I would recommend this product.
