Almost exactly two years ago I was asked to review a rather unassuming and humble set of woody earphones called the Thinksound MS01 and I remarked that I found them to be surprisingly well balanced and smooth earphone with a preference for vocals and detail over out and out thumping modern pop genres. At $100 I felt then, and still do now, that they are a cut above the rest in the budget category. Well 2 years later Thinksound finally unleash their headphone project, the On1 to the market priced at $299 (now I believe a special at $249) and overall this is a much more ambitious project but interestingly I have to say upon a few solid listening sessions lasting several days there is plenty of the sensibilities heard in the MS01 carrying over to the larger woody On1. I can tell that those that liked the MS01 will certainly enjoy listenign to the On1.

Naturally Aaron and his team have stuck true to their principles in producing another eco-friendly headphone which I do admire a lot and wish a few other companies would try to emulate. That being said at $299 and on-ear it also places the on-ear closed woody On1 among some very stiff competition such as the Sennheiser Momentum, B&W’s new P7, and Beyer’s DT1350. $299 is critical mass for many an avid headphone buyer, psychologically it is where things get serious for many so this is not a budget headphone, it should not get an easy ride but after some stiff testing among our national club members I think Thinksound have very little to worry about in terms of likeable audio quality.

    What an interesting model! May I know if.you`’ve had a chance to try it with iBasso DX50? I have esw9 paired with it and.curious.to.know the differences (especially for jazz, classical.and.female.vocals)

      The ESW9 is probably a little bit more refined for vocals than the On1 but doesnt have the same sparkle or extension into the highs as the On1 either. With the DX50 the On1 is easily powered and largely reflects the DX50’s own signature.
