The sound is almost identical in direct comparison with Beats Solo HD. The only advantage of the Beats is the better isolation of external influences and the (much) better bass.
However, the price / performance ratio really ingenious headphones. Would you buy repays again.
+ Design & Processing
+ Flat Cable (fewer problems with cable break or similar)
+ Sound
- Cables are twisted slightly and can not be very good untwist (but does not interfere much)
- Bass could be better, but is quite good
- Cable could be slightly longer (enough per se but from)
