Noice cancelling

Nice design. I use it flying and it works great. Has a long battery life. Need to upgrade the charger port to usb-c

Great Product!

I purchased these headphones when I traveled overseas to Dubai. Love that they do actually cancel out noise and are comfortable to wear. The charge lasted for a long time, and I will be wearing them for my continental US travel as well.

Best in their price range

For the price; these are gonna be your best in sound quality. I’m on my second pair. I tried some other companies but their sound was too tinny/thin.I use these around the house; cooking, vacuuming & even lifting weights but I wouldn’t use them for more strenuous activities like running.Very comfortable, sound great. If they got damaged I’d purchase another one.

Works GREAT!

Best purchase for the price. Works wonderfully. Love how it's cheaper than most on the market. I've had a pair since 2019, and just recently purchased my husband a pair. I use mine anytime I fly or want some extra quiet time. He uses his all the time for everything. Mowing the lawn, yep! Working out, yep! Working on his car, yep! They get used a lot. And haven't failed once.

Great value for price

Had lower expectations given price. But I was very impressed. Comfortable fit for long listening. Quality build. Nice cosmetic appearance. Fine noise reduction on long plane flight. High sound quality. High marks across the board. Could justify 2-3 times what charged.

Great buy!
