Volume problem with Sennheiser PC360 headset, any help is greatly appreciated.

Hi guys, I have a problem with my Sennheiser PC360 headset and I want to repair them, the problem is whenever I put the volume to the highest level with the volume control on the right cup of the headset, one side of the headset stops working or just sounds really really quiet (sometimes both sides do it), if I lower the volume just a little with the volume control then the problem goes away.
 
The theory I have about what's going on (I'm a rookie when it comes to headphone problems but I thought saying this could help) is that the volume control has some dust particles inside it, I tried blowing inside it just to see if that could fix it and that does indeed SOMETIMES fix the problem, but it's just a temporal fix, also if I tap the volume control it sometimes fix it temporarily.
 
If you know what's going on and/or how could I fix this problem (I suppose that would require opening the headset) I will really really appreciate it.
 
Thanks a lot.
 
(Sorry if this isn't the right forum, I wasn't sure where to post this).

Wait, so the PC360 doesn't have an integrated inline volume control, right?  What are you using as a source here?
 
edit: Never mind, I guess it does have one in the right cup.
 
It probably is dust or something like that...but normally volume imbalance happens when you turn them down, not up.  Anyway, have you tried compressed air?  That could help.  Otherwise, it's probably defective and you'll probably need to get a replacement to fix it.
 
The only other option is to get a more powerful amp that can actually power it with the volume turned down to the point it actually works.

Sounds defective. Get it replaced. Sennheiser should replace it as its still under warranty (they haven't been out a whole year yet).

I can't send them to warranty because if I'm not mistaken and correct me if I'm wrong the warranty only applies in the US and UK and I live in Mexico, the only opportunity I have to fix the headset is to open and fix it myself. :/

Yeah I've tried using compressed air without opening the cans but it didn't work.

Actually it only happens when the volume is at ~100%, if I put it at 95% (for example) then the problem goes away, it's not something that makes the headset unusable, it's something that annoys me a lot.

Yeah, I can understand how it might bother you...where did you buy it from though?  Contact the seller and tell them about this.  Don't see what else you can do.  I highly doubt opening them up will help anything.

I bought it from eBay new and sealed, it was sent to a friend who lives in Texas and when he came here, he gave it to me.
 
That sucks, I was hoping the problem could be resolved without sending them to warranty, I can't really do anything about it... :/

Ask Sennheiser and see what they say, maybe they'll have some additional insight on this.

I have just fixed this problem on my brother's PC 360. (The volume control is actually detrimental to the product, it's not needed for anything and only serves as a source of trouble)
 
All I needed was a soldering iron and a small cross screwdriver (and some spare solder, I extracted some from a burned-out power supply).
 
Remove the cushion from the earcup with the volume control. Remove all screws beneath the cushion. Pull the loudspeaker out of the earcup carefully (the wire is quite short).
Desolder all 5 wires from the PCB (volume control). Solder the two red wires together. Solder the two orange wires and the green wire all together. Use a piece of sticky plastic tape to isolate the two junctions from each other.
 
Re-assemble everything back.
 
The headphone will be permanently stuck at 100% volume.
 
Obviously don't do this while still under warranty - just RMA instead. Do this at your own risk.

Hey shtldr
 
I know this is an old thread, but I own a pair of 360 g4me i dont have any warranty left because they are quite old now  
My pair of sennheiser 360 G4ME just started having the volume button issue and I wanna fix it. I can easily follow your instructions. but I'm missing one part in your repair guide (this might be a stupid question) How do you remove the ear cup , because I just dont want to break them when disassembling them for repair
 
Kind regards

Did you mean the cushion on the earcup? Just grab it on one side and start pulling carefully, it should come off with a click. You don't need to remove the entire earcup from the headphone, the wire will prevent you from doing so anyway. After you un-screw and pull the loudspeaker piece out, the whole earcup will become loose (the driver piece holds the earcup and the frame together).

Yes i meant the cushion alright thanks mate ill give it a go.  thank you for your reply

I had the same problem with my Sennheiser PC360's which are just over two years old (and therefore out of warrenty). I got them open, but the soldering job looked a bit fiddly. On the off chance, I tried blowing hard onto the exposed volume control and the problem seems to be fixed (for now!).
 
I had assumed it was wear, rather then dust, but it appears that dust is the main cause, in my case at least!
