  Sound like some of the 80bucks I better invested. External construction quality below expectation. Sound quality well above. 
 
So far I listened to some Aphex Twin and Billy Cobham
 
grazie a tutti!

The K240 will sound much better with an amp, however, so I found your "no amp" requirement questionable (Grados fit that bill). Glad you like it, though.

I started digging into the amp issue, which I was worried about, and it seemed less present (by head-fiers' accounts) in the newer 55 ohm k240s. Most people described them as more relaxing soundwise and more comfortable to wear than the grados, and this made the balance tilt.

The sr60s were my original pick, since they are priced much lower in the US than in Europe where I normally reside... then I saw this price (cheaper than in Europe), thought about comfort and went for it. I might even get the grados on top of these in a cpl of months while I am still on this side of the pond. I still have to try some rock music on the k240s, that might make me shop again... who knows?
