Comfort: the ear cups are a little too small for my ears and end up squishing instead of surrounding - not tolerable for long-term listening given the bulk of these cans. Design: it's a big headset so the aesthetic isn't awesome to begin with, but the arch of the headband is more triangular/cone-headed than the pics suggest. Performance: quality seems decent paired w/ an iPhone 3G (3.0 firmware), but the range is ghastly even by BT standards - signal cuts out completely ~15 ft from the phone (I have another A2DP headset that almost doubles that and degrades quality more gracefully on the way out instead of cutting out completely). Thought I'd give these a shot since they're less than half the price of other over-the-ear options, but it's not worth saving the money if you never use the things. Back they go.
