These headphones are the best ones I've ever owned till now. I've used sennheiser headphones before and though they are good, they are very expensive. The ATH-M20x maybe an entry level headphones but the output is definitely top notch. many a times you will even forget you are wearing the headphones. Light and robust.
Pros: Perfect bass and treble balance for audio editing and mixing Lightweight Durable Comfortable for very long hours long cable length
Been using it for more than 6 months now. I've been editing commercials for more than 7 years now and this is by far the best equipment I've owned.
