I'm selling a 6XX that's in excellent condition and that I've installed a number of mods on. I chose mods carefully to retain the midrange magic of the Sennheisers while improving the openness, imaging, staging, and comfort of them. The stock headband cushion and earpads are not included, but otherwise all original packaging is included.

As for mods, they currently have ZMF perf. suede pads on them and I'll also include ZMF perf. lambskin pads, they have Custom Cans copper mod installed, and I include all the possible foam inserts for the mod. Custom Cans accidentally sent me two of their copper mod, so I'll also include the extra. They have Malvix Studio custom Fibonacci grilles that open up the sound a bit, and I also include the original grilles. I also installed a CapraAudio comfort strap that completely alleviates any hot spots or pressure from the stock headband cushion. Finally, I'll include Fog City Audio Sennheiser to mini-XLR adapters so that ZMF/Audeze/Meze-compatible cables can be used with the 6XX.

Feel free to message me with any question or offers, thanks!
