I use this headphone for at least a year.
These headphones sound good and not too expensive.
Apparently like any other opinion, I think it gives
very low (it should be own brand,
because I also have a microphone that sends the bass).
My problem is that I took this headset to dial:
On a bass sound that I use for techno
PForm it sound so I hear a high note
than the original (a buzz!). phnomne Ms.
with my Sennheiser HD-445 and less pronounced.

Conclusion: Good headphones for the costs, but
dial I think nothing beats the speakers
monitoring.
