Current EDC headsets:
Samsung HS3000 - main set, 'coz it's wireless. Terrible SQ.
Logitech Ultimate Ears 350vm - on airplane flights and as a backup when HS3000 runs out of juice.
Denon AHD2000 – pros: design, SQ. Cons: too warm.
Audio-Technica ATH-A700 – light, comfy, good SQ.
Audio-Technica ATH-AD700 - open design lets in too much of outside noise
Brainwavz beta – well built, bad fit, poor SQ, no isolation.
Sleek Audio SA6 – good SQ, crappy cable – fails too often.
Etymotics HF2 - durable, OK SQ, filters fail (clog) too often, unreliable.
A few Sansa Clip+ earphones.
Mobile phone (audiobooks)
Sansa Clip+, Sansa Clip Zip – overhyped crap. Don't last long; either headphone socket fails, either screen.
Acid Jazz, Ambient, BreakBeat, BreakCore, ChillOut, Contemporary Classical, Digital Hardcore, DownBeat, DownTempo, Drone, Dub, Easy Listening, Electronic, Experimental, Glitch, House, IDM, Indie, Industrial, Instrumental, Lounge, Minimalistic, Noise, Nu Jazz, Post-Rock, Trip-Hop and more.
Depends on the mood.
On the move. Isolation, durability & comfort are more important for me than SQ.
