in-ear headphones...good?

Archived from groups: rec.audio.pro (More info?)

hello,

i saw these Shure ear-bud things. Shure's kind of a lame brand except
for their 10db pads, but anyway they got me thinking:

if the build qualit was excellent, what types of acoustical advantages
could the in-ear setup provide?

i was thinking maybe:
1) eliminates room effects
2) eliminates outer ear effects
3) only needs to output a tiny amount of power, so you can use a single
small driver and still get low bass and a flat frequency response (kind
of like a measurement microphone in reverse)

i know headphones don't provide true stereo, but in terms of linear
response, could there be some advantages?

That's Poco. Shure's pads are switchable.

This they do.

This they do.

This they do.

What nobody says real often is that headphones and IEMs are
particularly sensitive to inner-ear effects.

(1) Small
(2) Good ones sound really good. Shure E3s for, example.

At least until you hear E3s or Futersonics. ;-)

Is anyone else here as fond of the STAX earphones as I am? They are
apparently correctly equalized, as they don't have any obvious colorations.
