Like many other reviews, I concur that these headphones are great, (and not just for the relatively low price). Lots of positives: eye-catching; great, punchy sound; good base; comfortable; novel build materials; pleasant company ethics even! BUT these little buggers have one design fault; (and your product is only as strong as its weakest point), namely: poorly secured wires!
After reading multiple reviews I can see how others were as perplexed as I was when, after a matter of months of fairly prudent and delicate use; keeping them in their little cotton case etc., one or both of the headphones cuts out. Upon further inspection I noticed that the only thing absorbing any naturally-occurring tugging on the wires is a little knot someone has tied in the cable just inside the perfectly-formed recycled, wooden casing, (presumably to stop it being pulled out of the earpiece), which, of course, is not secure enough and eventually means the wires slowly work themselves out of the back of the casing over time and eventually the connecting end tears from the soldering points at the back of the speaker!
