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.
