While this product may smell slightly of fish oil, which I?m not terribly keen on, but my eczema and itchy skin are very pleased after using it so I?m happy enough to keep using it. The headphones are doing some fancy realtime DSP when listening to music and the quality is very well pronounced for professionally office headphones. Also, there really isnt a big difference between the Velor and memory foam models in terms of sound changes. absolut traurig . Cant buy a smaller size because then the sole would be too short. The sound is incredible on these headphones. The directions are pretty clear too. Lacks bass. They are comfortable and light and they look really nice. Definitely returning this item to get my money.
