The sound was very crisp and bright...nothing mind blowing but very good...possibly a tiny bit thin sounding at times but the sound was not the issue.
The issue for me was the comfort.
The sound isolation is achieved by getting a tight fit onto the ear but after about five minutes it actually starts to ache.....the leather is clamped against the ear by the ultra tight headband. they are comfy at first but soon become very uncomfortable.
Make sure you give them a good try first if you really want them.
