Head Direct RE0 In-ear Headphones, with the nick name "Kylin", are one of the best In-ear headphones in the world.

The RE0 features an in-ear design with 15-20 dB isolation and the the best dynamic drivers around. The sound is smooth and has a transparent middle range. The current RE0 cable was made by PPE material, which is much more reliable than the old version fabric cable. Additionally the new L-shape miniplug is much better than previous plug, too.
