There's a crowd who loves tons of features packed into their headphones. Then, there are those who only desire the bare essentials, nothing more. In my opinion, the latter isn't getting enough attention from today's headphone manufacturers. But that's what Thinksound is all about. Its On1 are a prime example of headphones that don't try too much, but gets mostly everything right in the process. For a retail price of $299 (£179, AU$399 through online distributors), do these offer enough to please the headphone purists? These cans sure do look nice and the sound performance is stellar, but the feature offering is just a little too bare for the high asking price.DesignThinksound's earthy design ID is rooted (no pun intended) in using wood on each of its headphones. It's an addition that makes the On1 on-ear headphones in particular a natural-looking breath of fresh air amidst the competition, which is vastly made up of plastic and metal options.The cushioned headband is wrapped is a black fabric, which is embroidered on top with the Thinksound logo. Stretching down into the sides, the sidearm connectors conveniently display L and R, though, in my experience, the fit is no different even if you get it wrong. The tough, brushed metal sidearms can extend a generous amount, making room for heads on the larger size. Moving down to the cups, the headphones are coated in the black, matte plastic. The cup hinges are pleasantly flexible, allowing listeners to fold them up into the headband.
