The On1 headphones from thinksound purport to be a studio monitor in an on-ear headphone. That's a pretty tall order but one that I believe they have mostly fulfilled. The On1's have great top end extension, a lush midrange, and no real emphasis on any part of the frequency response range. At the lowest registers, they introduce a little noise which did distort the presentation somewhat, but it was only with the lowest bass. While I can't imagine any studio professional using an on-ear headphone for long term use for comfort reasons alone, the goal of a transparent headphone is one to be lauded. With their Eco focus, wood earcups, and extremely light form factor, these are an easy recommendation for those looking for on-ear headphones. Discuss "thinksound On1 On-Ear Headphones Review" here.
