Very good Ausdom circumaural design of the brand: it is comfortable to wear and the sound is really excellent with just the right amount of bass and treble never aggressive :-) The look is very nice: it looks like the helmets produced Denon, Sony, or Technics in the 90s ... a small and discreet vintage look really cool! The price is really hot compared to the look and performance: it looks like a helmet to 150 :-) The Bluetooth works well and the buttons on the headset to manage the volume, range change, or call answer ... Of course, you can also connect via cable to a non-Bluetooth device: the jack is on the left ear. Very satisfied, I recommend!
