Here are some days that I acquired this headset .. I bought it for my Sennheiser Momentum (One Ear) savérait quite uncomfortable over time because of the pressure it exerts. Regarding this KEF M500, is a small killer! Very low pressure providing a superb maintenance .. Well, the sound does not even need to do that in the eulogy, specialized sites are already loaded!
For headphones this price range, it does exactly what is asked, provides a pleasant sound while being ultra nomad. (Small + for the most beautiful effect, rigid and efficient case.)
