It was already not working well.
That's why I tried to fix them.
I got them from ebay uk for 8.90 gbp including shipping.
I sent a message to the store that they were faulty and they were kind to send me a full refund in just an hour without even asking for a return.
Depends on how careful you are when disassembling it. There are few plastic pins that you have to be careful not to break.
Now the problem is where can I get a working pair of MH1's from ?
I saw that they have them on ebay from spain for the same price incl. shipping.
But are they going to be ok ?
It seems as a common problem for that model to have a channel imbalance:
