On another note, my Koss KCS75 Pulse Clips arrived today.
I am seriously impressed for the $9.99 sale price.
Not as rich as the Q701, and the separation between instruments and notes isn't as distinct, but the little Koss is an amazing deal with basically no unpleasant qualities. I didn't compare them side-by-side A/B, but I don't feel dissatisfied after being brain-attuned to the Q701 for a fairly long time. First thing I noticed was it has pretty great impact, listening to Wilco's "Whole Love" you really get a sense of strings being hit and the acoustic guitar pushing sound at you, you feel how hard the musician is playing. Good cans to rock to. I also plugged them into the relatively crappy (re: noisy) aux out of my computer speakers while playing Starcraft II today (I reached #1 in my division today, first time ever Whooray!); the background noise didn't bother me, and what I DID hear was much "fuller" and... more... intense and involving, making my old $80 Sony computer speakers sound laid-back and thin by comparison. Bass presence was much better. The low-mids may seem a little sucked out or overshadowed (not as evenly rich/full through the freq range as the Q701), but overall if the mid-bass is boosted then the mids are "neutral" ish and the low-trebles slightly lifted.
The only thing I would say against it, is perhaps the Koss' sound isn't as relaxing and may be tiring to listen to music with for a longer duration (probably done after an album's worth). That said, I played music and games with them for 3.5 hours today, maybe I got used to it but the Koss never seemed harsh or painful. Physically, the clips didn't bother me even though I was also wearing glasses, the way they rotated behind my ear didn't interact much with my glasses stems, and they didn't hurt (though taking them off was kind of like the relief I feel after taking off socks from my feet).
The biggest come-away is how worthy these sound, even fun. Their price begs the question: if you're enjoying yourself and having fun, why pay more? There are reasons, but still I think EVERYONE ought to own one, even if it's just to reference if an upgrade is worth the money.
