-Might be a personal preference, but they sound genuinely excellent. There's a spike in the response around 9KHz, but it's not apparent to me - I can't stand bright sounding headphones (I binned a pair of Grado SR-80s because they were too bright) so it probably won't bother you either.

+Might be a personal preference, but they sound genuinely excellent. The frequency response with decent amplification is very flat, but YMMV with high impedance sources. I've run them from phones, HP laptops, Macbooks, and dedicated amps, and they sound great in every case.

These are very high impedance, so they **really** need decent amplification to make them work properly.
