For in-ear 'phones the Creative EP-630 / Sennheiser CX300 is good value
(search Amazon for reviews, both are similar), but has a bit of a
'rappers delight' bass hump which may not do too well with classical
music of a certain sort. ...

WRT the CX300 in-ear monitor (IEM) I found this:

http://graphs.headphone.com/graphCom...Type=0&graphID[]=603

Which seems to confirm about 15 dB of bass 'enhancement'.

It's interesting to browse through the site's measurements and display
comparisons of, for example,

- the Shure families (old models and new models)
- the Ultimate Ears models
- the Etymotic models

I think I see (depending on whether I can trust the measurements and
interpret them properly):

- Bass in IEMs is often enhanced either a bit (3-5 dB) or a lot.

- Getting any treble above 8 kHz can be problematic (let alone a flat
response). Actually I suspect ear canal resonances may play a role.

- The Etymotic ER-4s with a single transducer get 'better' treble
than almost all IEMs - even three-transducer types. They seem to
have their IEMs better sorted than the rest.

I'm late to this thread, but wondered if anyone knows of phones with
-attenuated- treble. I'd ideally like to find phones with very rich,
solid mids and sharp rolloff above. Kind of like the stock iPod
phones, but even more in that direction.

Koss "The Plug" are IME very bassy.
