Hi, I have the Massdrop HE-4XX headphones, but the cable that it came with is really short and I need something that's at least 3m long. These headphoens have 3.5mm connectors on both ends and strangely enough, I haven't been able to find any cables with 3.5mm male connectors on both ends! The only cable I found was from "CablesOnline" which is a 6ft stereo to mono splitter and that works fine, but it's still not long enough. I'm not keen on buying a cable that costs more than the headphone itself. I'd really appreciate suggestions as all my searches have come up empty!
