I just did a comparison on that link for why headphones are bad for mixing.
I don't think I'm mixing? I just want an accurate sound of what I sound like. I tried to do the test of listening to something with headphones and then speakers, and it's suppose to show that the highs are much more prominent on headphones.
Please go to head-fi forum, they're freaks and as knowledgeable about headphones as people are here about recording. It matters what headphone you have. Some are more bright than others.... sony sa5000, grado's,
beyer dt880. The senn 650 is know to be dark.
When I did the test versus my $100 computer speakers (full disclosure: altec lansing, I know they're crap) the senn 650 was not bright - it did not present highs at a higher volume.
Moreover, the voice was reproduced much more accurately, the overall sound, clarity, the transients, the attack, the detail, the texture, timbre etc. was all way better with the headphones than speakers.
Imaging does not matter for my purposes, it's only mono.
And I'm doing this for practice sessions, so it doesn't matter that my car stereo, home theater, boombox, is going to color the sound, each in its own way, and therefore I shouldn't master the sound so it's already colored.
From the website headphone.com (headroom corporation, probably one of the most knowledgable headphone dealers, and maker of a stereophile class a headphone amplifier) says of the 650s:
The measurements of these headphones are as close to perfect as we’ve seen, and the sound is as close to perfectly neutral as we’ve heard.
They measure based on the sound measured inside the ear canal, not the frequencies emitted at the driver.
