Those who expect a super HiFi Headphones for this money, which is certainly disappointed. This is already clear, if you indicated on the packaging frequency response of 100 Hz - 16 kHz reading. The first advance has nothing to do with hifi. However, the handset sounds quite acceptable, it is quite powerful in the upper bass and fairly balanced in the mids and highs. But when it comes to detail, spaciousness, clarity and fine detail, I prefer to take my Sennheiser HD 580 on my system, which is then a difference as you would draw a thick curtain aside. Nevertheless, on the go and for those who Hifi only in MP3 form know quite a reasonable alternative. The workmanship is quite good, but you should know that the little ear pads are in most ears on them, and to those not enclose. Conclusion: Pure sound rating 2 stars, price range relation 4 stars.
