Which In Ear Headphones to Choose

Hi

I have been looking to get a "proper" set of in earphones for a while now, but would appreciate some recommendations..

They will be used with an iPhone - but I do not need a microphone or controls
The music type (showing my age) is Rock (Led Zep, AC/DC, Deep Purple, Hendrix type)
Blues - early to current
Some classical
Some Pop (mostly 60's & 70's)
Some vocalist - Beth Rowley, Shirley Bassey, Frank Sinatra, etc etc.

OK I have been looking at various brands and reviews, and with a budget of up to £200 I like the "look of" Etymotic kit either the ER4-P, ER4S or HF5, but am open to alternatives.

The key factor being quality of sound reproduction.

Can anyone assist?

Regards
Peter
