Summary: Good sound quality at decent range. Bit base heavy but nothing that can't be sorted with EQ. Very uncomfortable after shot periods. My ears feel pinned down and hurt after 30mins to an hour. Noise cancelling is good. First pair one side not working so had replaced. After few months the plastic sides have cracked pretty bad but that maybe have been my daughter dropping them.
Summary: For the price they should be great, but sound quality is poor and build quality is flimsy. You also look a like a Doctor Who Cyberman when you wear them because they are too silver. Even my"free with phone" samsung in-ear headphones sound better.
Summary: Broke down after about an hour's use. Bluetooth connection wouldn't work. Light permanently on. SQuestionable build quality, very plasticky. Sent back for refund which Amazon provided. Don't want to take another chance on these. Will run with the Philips Fidelio BT headphones in due course.
Summary: I wanted something else instead of mainstream Bose - I used to think Denon made decent products. But what a disappointment... - Build quality is rubbish. You can actually see the glue from the ear pads on the plastic surface. They are to bas heavy. Really poor sound isolation, and you can't tell if the noise cancelling is switch on or off. Some kind of ratteling noise from the speakers when you walk around. No Android features on the device.
Good-ish quality of sound, garbage quality of device.

Summary: I managed to use it for 5 hours till it broke. I got a deadlock on bluetooth syncing, I wasn't able to turn it off or sync it with any device. I had to let the battery deplete. The right rotor wasn't working for turning the volume down (only up). The left button on the middle of the left rotor wasn't clicking like the right one (half broken). The sound was quite bass-y. All that happened in less that 10 hours from the time I got it. I am asking for a refund today.
