Transformer Running Hot For my Pioneer SE-DIR2000C surround sound headphones.

Dear Pioneer,
I recently purchased a pair of your superb SE-DIR2000C surround sound headphones but experienced the following problem with the 12V DC 1000 mA transformer. When plugged in and in ‘Stand-By’ mode, there were no problems but when the unit was switched on from the ‘Stand-By’ mode and after about 10 mins, the transformer would start to get very warm – I might add that the headphones were not even on the charging unit at this time. After (2) weeks of use, the transformer finally died/failed and I have been unable to use it again. Fortunately, my friend owns the same headphones and after borrowing his transformer, I was able to power my charging unit on but only to prove that it fortunately still worked. I am now sure that the problem lies with the transformer itself and specifically, with the 1000 mA rating of the transformer unit. Could you possibly help me at all and will I be able to solve this problem by say, obtaining a new 12V DC transformer but with say, a 1500mA or 2000mA rating.
I don’t know whether or not I missed anything from the instruction manual but unfortunately, it is in Japanese text but I don’t think there is any other way to operate this headphone system other than to leave it permanently in charging mode when the headphones are returned to the charger in ‘Stand-By’ mode. I have experienced this symptom once before when a transformer was rated at a lower wattage than the equipment it was powering.
The spec of the (2) rechargeable AA batteries is as follows:
1.2v Typ.2100mAh Min.2000 mAh WEX1019-A
The (2) rechargeable batteries are: Nickel Metal Hydride AA batteries.
….. What would happen if I obtained (2) more Nickel Metal Hydride AA batteries but with a rating of say: 2500mAh?
Yours desperately,
Rod Whitehouse.

My coby headphones doesnt work good. i have to twist it at the bottom near the jack and bend the rubber for it to work..and now it had gotten could i fix it or open it and fix it...

To fix it you would have to repair the short in the wire. You could take an old pair of headphones and replace the cord a few inches up from the connector.
However, Coby is not known for their quality sound or headphones. You would probably be better off purchasing either another pair of Coby headphones or a better known brand with a warranty and excellent customer service.

No sound coming from the "right" side of the headphone?? did I deactivate something??

Sounds like the connection for the right channel is interrupted somewhere- check at the point where the cable enters the actual headphones. sounds like you might need new headphones if yours don't have a removable cable.

Skullcandy Hesh, One ear louder than the other?

So this was happening to me the first day I got these headphones. This might not be the same situation for you but I simply was not pushing the cord into the headphones enough. You have to push the input into the headphones until it pops or clicks into place. Once I did that, the sound was superb.

Sound from only one headphone

I purchased an AW 771 set in "as is" condition which on arrival produced output only from one side. Repair was effected by removing 8 phillips screws, 4 from each side, concealed under the ear-surrounding doughtnut-shaped cushions. To expose those screws, the ear cushions must be pushed from their center toward the outside. Black screws in back holes surrounded by black acoustically-transparent cloth does not make them obvious.

I used a volt-ohm meter to find a discontinuity at a failed solder connection. Resoldered that connection, rechecked electrical continuity to be certain all connections were good. Tested with batteries installed using an audio input. Both sides produced sound. Replaced screws and they have performed very well since then.

I hope this Model AW771 experience is helpful in restoring your AW-721 to working order.
