I'd like to add this comment as I've used this headphone for a year and a half now. I bought this May last year, overall great headphones, but just realized it's not built to last long. I've taken amazing care of this thing, wrapped up the cables after every use, kept it in it's own padded pocket within a very well padded office bag during my daily commute. I just noticed today, the left headphone case is cracked, the unit probably still works, but was hoping I could use this for alot longer, but now I either have to repair it or get a new set. Having this broken piece dangle out of my ear is not an option and this exposes the internal wiring.
Attached a pic so future buyers are aware, again I'd love to recommend this product, but given that it's broken, and I can't find virtually any information online about the company or any warranty it may provide as their site is in all chinese, it's really hard to recommend this. It's a shame, it sounds great otherwise, but I guess you get what you pay for, since even without massdrop, this comes at a pretty low cost.
on a side note, looking at the right headphone, I can see the start of another crack there, so looks like that side will meet the same fate.
