Sennheiser PC37X randomly goes bad after disconnecting the cable ?
Greetings, Yesterday I was using my headset like normal with my macbook, just listening to music and on a call with people like usual, and the headset was perfectly fine. The stock wire that came with the headset is extremely long and yesterday it annoyed me very much that it kept getting tangled with itself, so I decided to see if the cable is replaceable. I pulled out the cable from the headset and saw the adapter, and looked online for a replacement. Upon plugging it back in, the audio sounded extremely muffled and washed out. Im not sure what I did wrong to make it mess up like that as I've always taken good care of it, ive had it for about 2 years and its always just been chilling on my desk, but anywho I thought the cable just went bad and ordered a replacement. The replacement came, and the issue is still persistant, so I am not sure what the issue is I've tried multiple different headsets and the issue is not with the port, and I also tried it with my windows laptop and...

Would the adapter pass the higher 230v through the cord to the unit and damage it or is there some kind of power element that could stop this? Really should of been more information now I'm really worried, it turned on for 5 seconds, I unplugged, replugged 2 mins later and nothing (obviously it wont come back on with wrong power)
Posting my story so others can at least be aware, trying to source a power adapter with 15V output for Australia now
I haven't received mine, but glancing at the schematics online, there doesn't appear to be a fuse in the O2. There might be one in the adapter. Schematics :
Hopefully it is just the power adapter. You can check this without any further harm to the O2, if you have a multimeter, by measuring the output of the power adapter with the O2 disconnected and see what is the AC voltage output. If there's no output, it meant it took one for the team, hopefully quickly enough to spare the O2. Be very careful not to short the adapter when testing.
Good luck. And did you say you're in Australia? And you got your O2 before me (in California)? *mutters curses at UPS under breath*
Its a really well built unit you'll enjoy it :) Not sure about the sound lol
Why didn't MD put the information *front and centre* on the drop page!?
I think I got to it quickly enough to prevent any damage, but I've ordered enough electronics from overseas where the distributors automatically include a 230v capable adaptor or an alternative that I hooked this up without much concern.
Come on MD. If you are happy to take our Aussie dollars you should damn well provide the correct equipment at the checkout page.
If you have problem with your unit. Just go ahead and open a ticket with Massdrop Support via the support page. We'll take care of you.
I'm not sure what you meant about power transformer / power adapter though. From what I can tell (since I *still* haven't received mine) the power adapter / wall wart / whatever you want to call it outputs 15V AC, meaning it is most likely just a step-down transformer. If you can find one in Australia that outputs 15V AC with the same (or better) wattage, and have the same connector, you should be able to use it.
I tested my unit with the multimeter at work and attaching a dummy load to the output terminal, and came to the conclusion that as I wasn't actively amplifying when I plugged in for the first short time (<5 seconds) that it was very close to being damaged but only heated some of the wiring insulation.
I have since tested the unit with several sets of headphones at 10%->100% and found no issue using 2 x 9V batteries to power it. Am unsure if I will bother tracking down a compatible adaptor though.
