I have a set of Sennheiser RS130 headphones that are probably 8 years old or more. The look like this:http://ift.tt/2BKxDBM, when i put my headphones back on the charging stand, my computer shuts off. Presumably, this is due to a static discharge. This is not every time - maybe only once every 10 times i put it on the stand.I tried dropping the headphones onto the charging stand (from an inch above or so), thinking that maybe it was me touching the metal charging bars. But still i was sometimes getting the same effect.My next thought was to use an extension for the 3.5mm jack - that way i could disconnect it from my computer prior to putting the headphones on the stand. Totally effective. Except that i just went to plug the extension back in and it killed my computer again. So apparently this is a great solution for placing the headphones on the stand, but i still get a surge when i reconnect. I was careful not to touch any of the metal pieces on the connectors, so it doesn't seem like it came from me (which fits with the fact that i can drop the headphones on the stand without touching them, and it will still short out).Any thoughts on what i might do? I searched around for a surge protection with 3.5mm, but that doesn't seem to exist.As far as i can tell, i have these options:1) Buy new headphones. This sucks, because the only wireless open back RF headphones that i can find are Sennheiser's flagship model, which are 300 bucks or more. I really want open back, and the ones i have are incredibly comfortable. I can wear them all day and go hours without noticing that i'm not even listening to anything - the open back means you can hear everything around you (i know lots of people want isolating headphones, but that's not what i'm after), and they're so comfortable that they just disappear.2) Never use the charging stand. Luckily, these headphones use regular rechargeable AA batteries. I have lots of those, so there's no reason i can't just charge them out of the headphones. It's mildly inconvenient, but right now this seems like the best option.3) Try to make a surge protection circuit. I found some surge protection circuits i might make, but none of the examples have anything to do with audio cables - not surprisingly. So i really have no idea what values i should sub in for the resistors, etc. I'm not confident i can make something that will actually transmit the audio without affecting the quality.4) Give the static somewhere else to go? I'm not sure how best to do this at the moment - maybe touch the connectors to something else before putting the headphones on or something?Thanks for your help! via /r/DIY http://ift.tt/2l8Ff5E
