Their only positive aspect is the very good and durable construction and the flashy packaging.
Their sound is unacceptable and distracting.
Annoyingly mid-range heavy, muddy bass, and excessively high treble. I have 3 sets for TV monitoring use, with only volume adjustment and no frequency interventions, and I really prefer working with some no-name "kiosk" headphones. This price does not justify neither the name of a once good company nor this useless product. The box says "Professional in-ear monitors".
Seriously now?

For in-ear headphones, they are very good. Good bass, lacking a bit in the mids. They cut out a lot of external noise with the proper ear tips. Definitely better than the similarly priced Shure ones I had before.
