Volume Imbalance on Sony MH-1C, Will recabling solve it?

post #1 of 8
Thread Starter 



I own Sony MH-1C, lately as some of you know, its suffering from volume imbalance, with right earbud louder than left earbud. Today just to clear my doubt, I generated a mono tone from Audacity and played it, I can here the imbalance clearly, but here is the interesting bit, when i set the slider of Left at Zero and Right at 100%, still some sound can be heard on the left earbud (remember right= louder when set at equal level). I just want to know will recabling it will solve this, is this earphone's driver fault or the cable's, Ive checked from other sources too, same story there. Im afraid I cannot buy these in my country, as these are not available anymore. Please provide your valuable comments.


Thank you.

The left and right are separate physical connections. If you pan hard right you shouldn't hear anything in the left. What are you panning with? The player?

no, from windows sound mixer i.e. from sound properties>levels>balance

Probably the tip filters. They're stick on. Carefully remove them and see if they then balance. Your's doesn't sound like a cable problem. Anybody know if you can get replacement filters?

Did you try removing the foam behind the filters too - might be worth a shot. My first pair of MH1s ended up with very low sound on both sides after a couple of days of use. I tried recabling them but it didn't help. Turned out the filters were faulty - when I removed them the sound level was fine .... but they sounded too bright and not as smooth. Ended up using them with one side of the filters slightly lifted + the upper treble boosted a little, and they sounded pretty good. I have a new pair now but it would be great if I could get some replacement filters for the old pair.

I'm from India too. You can get an MH1 (not MH1C) for about Rs 2000 from an ebay-india sellar:




These ship with only one extra pair of tips - I got 8 extra pairs with my MH1s from an ebay-uk seller. If you want a pair with more tips you can try asking this ebay-ie (Ireland) seller how many spare tips they include. They're almost the same price including shipping:





Then, either:


1) get one of the adapters mentioned on the main MH1 thread, .... or


2) do a fairly simple mod either at the remote control unit or at the jack (details in the main thread) .... or


3) recable (a bit of a pain coz the wires are so fine)


Much cheaper than getting the MH1Cs today :)
