Creative EP-630. This is an absolute surprise, and a real killer! Good sound for only €29!
Sure, it does not have the grandeur of a Sennheiser HD-650, or the refinement of the Etymotics ER-4S, but this is a very musical headphone. It has a good spatial field, quite some bass (a little bit too much), fierce treble but never any sibilance. And most important, quite some energy in the mid, the area where most of the musjc and its drive is situated.
This is a perfect travel companion. Highly recommended!
