  • Listening fatigue was not an issue over longer periods of time, thanks to the high-quality leather coverings on the ear cups that reduce ambient sounds and can be removed or changed to suit your skin type.


  • Poor build quality: The ear cups and headband feel cheap and the headphones creak when handled.
  • No noise cancellation: Outside sound easily seeps in, which is a problem for commuters or people in noisy offices.
  • Uncomfortable fit: The pads feel too thin and don’t provide much isolation from outside noise. The headband can also press down on your ears if you wear them for too long.
  • The sound is not incredibly punchy or powerfully moving, but instead can seem thin at times.
  • The design of the speaker lacks some finesse with an appearance that is more industrial than high-end.
