Noise cancellation is rated at 95%, so reviewers say if you're looking for 100% cancellation, you might be better off splurging on a big name brand.
BuzzFeeder's Maitland Quitmeyer comments:
“Actually, I bought it after I first introduced it.” — I'm considering purchasing AirPods Max, but I'm very picky about the fit of my headphones and am sensitive to my ears overheating when wearing certain on-ear headphones for long periods of time. So instead of (or before) committing to the $500 version, I thought it would be a good idea to give these a test run. All in all, I love them so far! Very comfortable and won't make your ears overheat. The sound quality is great even to my non-expert ears! And the noise canceling was perfect for me. It blocked out the annoying city noise and allowed me to completely immerse myself in the music. ”
Promising reviews: “These headphones are one of the best purchases I've ever made. Firstly, the presentation of the headphones is great. They come in a silky oval bag and have several options for audio input. Video/Audio, synced! Girls who know it know it. Some headphones tend to have lag, but these headphones don't! At maximum volume, it's pretty hard on your ears. Not only that, but I was also impressed by the long battery life. I've used these headphones for about 4-5 hours straight for several days and they still have over 50% battery life. These are the best headphones I've ever had and I would recommend them to anyone.“――Ken
