I've had Equation Audio RP-21. It's quite accurate, and a nice deal at about $80. Better is Sennheiser HD600, which IMO produces the most correct timbre, although you should use an amplifier with it.

Any opinions on the Beyerdynamic DTX-900?

I read on head-fi.org that people prefer them to the Beyer DT-440.

I use Beyerdynamic DT-250. Fully closed and comfortable when used for extended periods. I also use them for live mixing. Very good sound. Studio quality which means high resolution, neutral frequency response and no boosted bass.

Peace.

I give up! I went to Guitar Center. Tried a high-end Beyer. Nice, but too expensive.

Anything within my price range was boxed up, sealed. No you can't open the box to try them on!

Meanwhile, I bought a graphic equalizer and I hooked up an external amp. (My DP is a CLP-240.)

Now, my cheapo phones sound better. But I'd still like something better, so I put the Beyer DTX-900 on my Amazon wish list. Around $70.

End of story.

£25, awesome sound quality.
