Here is a pleasant little surprise - a very light and comfortable on-ear headphone that sounds great and doesn't cost a lot (~$105 USD street). It has a trifle more bass and slightly less treble than the average Grado, which I think works well for an ideally-portable headphone. Apologies for the photo linked in the review - the colors didn't reproduce well.
