Hey guys, I did a very long and detailed comparison between the DT880 600 ohm and HD600 recently and have some further thoughts.
Overall frequency balance: HD600 > DT880 by a lot
Soundstage: DT880 > HD600 bit a little
Comfort: About equal, possibly a tad better on DT880 due to HD600 clamping
Bass Response: DT880 > HD600
Speed: DT880 > HD600
Maintenance: HD600 > DT880 by far
So to say the least, I can see why the DT880s are popular. But their treble and mids simply cant match the HD600. A combo of these 2 headphones would be ideal

Despite of all the pros on the DT880, I still like the HD600 more. It has also made me realise just how good the SRH-840 really is. If the 840 just has a little smoother trenle, I would probably prefer it to the HD600 due to its great bass response.
I also popped by a JayCar store and tried the FA-003 clone. Its actually more of a HM5 clone, has a case and extra set of earpads (all pleather) and looks identical to the HM5. No offense to anyone, but I didnt like them. There was a hole in the sound somwhere in the mids. I suspect this may be the dip at 300Hz that Im hearing. The highs were smooth though and it was pretty cozy but I just couldnt get past that problem.
I plan to do a final shootout between the Q701 and HD600 vs SRH-840 before making my purchase. To be totally honest, Im wondering if should ... the SRH-840s are just great.
Can anyone tell me what to expect of the Q701s? Do they have less bass than the HD600s?
Cheers
