Awesome head phones.

I figured I would need an amp to adequately power the headphones, seeing how the sound source (my phone) was not capable of putting out a sufficient amount of power or whatever

These phones are really amazing

Good while they lasted right head phone went out randomly.

(If your want great head phones with a good price get these.)

No better phones available for the money , u won't regret buying these...

Very comfortable professional sounding head phones.

I compared so many so many headphones and did so many reviews on this and every year the M50X is rated one of the best head phones
