--- Quote from: saratoga on March 14, 2007, 01:20:00 AM ---You can use foobar+rockbox to calibrate your EQ for your headphones.  In foobar, you can use the following to generate a 400Hz 10 second test tone:

tone://400,10

Copy that to your clip board, goto edit, and chose "insert track".  Chose a few frequencies corresponding to the EQ bands you want to adjust in Rockbox.  You can only change 5 at a time, so this shouldn't be hard.  

Then use the file converter to make it into a wav/flac/whatever file and load into rockbox.  You may want to replaygain them in foobar first, since I think foobar gives them all equal energy, not perceived loudness!  Once in, play them while adjusting the Rockbox EQ.  You should set the EQ so that they sound about the same volume, that way Rockbox will produce an accurate sounding copy of your music.

Once you've done that, you may want to tweak them a little more to taste, but thats a personal call.

thanks, i'll give this a try in the morning see if i can get it figured out.

Nate!:
saratoga: Wow that's excellent advice.  I think I'll try that also.  It's sort of a scientific approach to adjusting your EQ.  What frequencies do you tweak?  Do they correspond to specific instruments or perceived ranges?  (i.e. cymbals, vocals, snare, bass drum : or highs, mids, lows)  

I read other threads on the topic of EQ recommendations.  It has always been a daunting task figuring out which frequencies to adjust and what levels to set them.  But this kind of makes it seem simple.

Thanks for the good advice.

Mikerman:
There also is a thread at Misticriver in which people posted their EQ settings, for copying to your player.

Included are some Shure EQs, including for the E2C.  Of course, it all depends on your personal preference (I tend to keep things flat), but it's a way to start/experiment.

Arj:
I think I will have to try Saratoga's idea too.  I tried adjusting the eq based on  a frequency response chart for e2c's.  That involved boosting the upper end mostly.  In theory that should produce a flatter output.  OTOH, I know I don't hear the high end like I used to, so I've boosted that to compensate.

soap:
For iRiver owners, the following point is ignorable:

iPods and IEMs (which are most all 16ohms) have a whole separate issue - the iPod's poor bass response with sub 32-ohm loads.
