JVC HA-RX900 Stereo Headphone - Wired Connectivity - Stereo - Over-the-head - HARX900 - Buy.com
They're fairly lightweight, not as feather-light as the Denon 1001s, but definitely are built more substatially. They look heavier than they are, but are quite comfy. The large earpads fully enclose my ears with a good solid, yet non-clampy, feel.
As to SQ, the best I can compare to is the Denon 1001 because that's the only phone I have to compare to. Out of the package these JVCs have a better developed sound. The Denons are coming together with break in time as the mids and highs were very recessed when new. The JVCs don't have that problem. While the bass isn't quite as tight as the Denons, it's definitely fuller on the JVCs.
Using an un-amped iPod 5.5 as the source, I listened to Enya: The Memory of Trees, Meat Loaf: Bat Out of Hell 3, and Pantera: Vulgar Display of Power. The Denons did better with Enya, the JVCs with Pantera, and Meatloaf was a toss-up with a slight nod to the JVCs.
Overall, NIIIICE phones for the money.
