"Well balanced, comfortable"4.0 starson by SpiderM69
Pros: Balanced EQ, good bass, spacious soundstage
Cons: Don't like the cord style, but that's extremely minor
Summary: I didn't care for the earbuds that came with my Zen V Plus, so bought the Bose in-ear's. The Bose were awful - so bass heavy that the other frequencies were masked to the point of making everything sounding muddy. I sceptically bought the Sony's, found them to be a huge difference. Far superior to the Bose. High's, mid's, bass are all balanced and nicely reflected. I'm also impressed with the sense of spaciousness.
I'm a musician so I listen closely to the balance of frequencies and soundstage placement, as I'll be listening critically to my tunes. I'm happy with the Sony's and didn't want to (and now don't think I'll need to) fork out top dollar for the higher end in-ear's.
