    Hey guys,

    As you may recall Marv sold a pair of SR-007 MK2 with channel imbalance, I have been trying to find a repair center here, but it seems that I either don't know how to look or they don't exist. Any place/person you guys know of that could maybe repair them for me? If not can someone explain to me what's the sud's repair method as I may want to try that? Thanks for your time, everyone.

    Regards,
    Y

    Open up the headphones, get the membranes out, rinse them clean, then coat them in 10x diluted floor detergent. Dunk the whole membrane in the solution and then dry them (without heat) if you don't want to touch the mylar (which is actually reasonably tough). Alternatively, coat the side that isn't facing your ears with as little solution as necessary to get an even coat - that is the usual advice, but I think both approaches work fine with the diluted solution.

    Three things to beware of:
    1. The drivers (stators) are connected to the cable by three tiny wires, try not to break them, and take a picture just so you know which terminals to solder them to if (when) you do break them. The membrane is the clear plastic thing sandwiched between the stators, which isn't connected to a wire.
    2. Dust ingress - if things get really bad (noisy), you may need to wipe the stators clean. Keep a blower handy. Note: the noise from dust ingress sometimes disappears by itself over time.
    3. Take care not to reassemble the driver backwards.

    If the whole thing goes to shit you can also contact this guy: https://www.head-fi.org/members/julez.170988/

    I sent them an email, hope they can help me with this.


    I contacted the guy to try and figure out his pricing, if it's cheap I'd rather let an expert do it :)

    The 007 drivers are fairly robust, more so than most headphone drivers. Most of the breakable parts can be repaired. But anyway, good luck one way or another.
