I am extremely happy with the sound quality of this headphone. This is very comfortable also. You can listen music with this for very long time without any irritation on your ear. To get the best out from this, you will need a good DAC & headphone amplifier. Currently I am using it with NAD D3020 bluetooth DAC cum amplifier. The result is extremely satisfying. It is loud but never become harsh. Bass is not muddy & mid is also very good. Yes, I recommend this product strongly.
