I'm in marathon calls all day long, and I had yet to find something that is comfortable to wear all day with glasses until these. I'm a heavy user of headphones, and I have some pretty specific needs - they need to have good battery life, great sound, and they have to be comfortable. All the rest is gravy. These meet all of these needs and then some. They sound great - comparable to my Bose QC35 (maybe even a touch richer), last all day with ANC at full power (the wireless charging is a nice touch), and have been worn for entire days with glasses without pain. I never thought I'd see the day! For the price, these really can't be beat. I prefer these to headphones that cost more than a hundred dollars more!

Fantastic product. I’ve used them several times on airplane flights with great success. I have severe tonight us and these earphones provide a good deal of comfort when my symptoms appear. The noise canceling feature along with Bluetooth capabilities are excellent

Sound quality is excellent. They have a slight boost in bass but not in a bad way. They are warm sounding and never get sibilant. Detail retrieval is great as are the vocals. I really like this headphone as a compliment to my Open Back Sundara's and HD 560's. My only other closed back headphones are Audio Technica M40x with ZMF pads. They all have different sound signatures but this Wireless headphone is one of the better closed back headphones I have heard. The earpads are comfortable and noise canceling is good enough for what I need. I really like the hand gesture over the ear cup to lower the volume for what you are listening to and raise the mic volume so you can hear the person talking to you. Very nice set of headphones.

I'm not an audiophile by any means, but these headphones do the job for me. Sounds is good, noise canceling is good, and the swipe controls are pretty neat. Only reason I knock 1 star off is sometimes the swipe controls don't recognize what I'm doing (like taking off my headphones), and if I wear the headphones for too long (multiple hours without a break), it can start hurting the top of my head.

I've had the Know headphones for several weeks. It took me a little bit to get used to the different controls but I'm impressed! The fact that they will pause the app that is playing on my iphone when I have to slide them off for a second is great! Neither my former Bose over the ear nor Bose Sport headphones could do that. They're comfortable and the sound quality is great!
