heya,
The following for your consideration,
1. Grado SR60 - change the pads to the bowl type. more comfy i find. Most comfy headphones ever used, sounds excellent, ear fatigue is negligible. balanced sounds and excellent bass response. imho. abt $120. at Music by Design, Adelphi.
2. Sony MDR-A44 foldable type. comfy and light. sounds great to me too and pretty balanced. not too over hyped bass and highs. or maybe am just used to it. anywhere shld have. maybe about $40..?
Not a fan of isolation type earphones cos it sounds a little unnatural to me, and ear fatigue sets in like pretty fast to me. so i prefer the open types, where there is leakage admittedly...
3. The other earphones recommended by friends are Sennheiser and Audio Technica. But never really tried them so can't comment much.
hope this widens your choices. cheers
