The PRO 550 is an excellent product and I like the real stereo music it produces

well, think how your dad used to yell when the music was too loud.

I highly recommend this product to anyone who enjoys music.

I would totally recommend them to anyone who likes crisp, clear, lively music with a deep, defined bass that does not overpower the music

Very nice with bassy, bouncy music such as trance, downtempo, drum & bass, house

Beyer Dynamics DT900 are "open" headphones, so no loud music in public

I'm not a sound pro in any instance, I just want to enjoy my music in an affordable way and to hear the clarity, details and the bass...

I'm not generally an electronic music listener, but the fact that these headphones make electronic music sound so good has got me into listening to a lot of Dubstep and similar music

If you just want to look like every other 20s year old who pretend they love their music and tried to look "cool", go buy a "Beats by Dre" and/or "Monster" and you will look just like anyone of them.

If more people knew music could sound this spectacular

The 750 is very lively and fun to listen to with your favorite music

Music is really where they shine, I would re-buy them in a heartbeat.

You hear things that you have never noticed before in your favorite music

Sweet MUSIC goin' on here People !...but keep in mind, "These closed-back headphones use the STIFFEST DRIVERS available

I have worked as a studio engineer and published music for over 15 years and currently work in the film and television industry as a production sound mixer but my true love is music

PRO 900 S can distinguish very detailed sounds，Bass is superb as good as the MF and HF，I highly recommend PRO 900 S for You will not be disappointed with the sound

That was quite unexpected!There has been quite a ruckus about the simulated surround sound called 'S-Logic' on these headphones
