• You can get replacement parts here.
• Please reply if you have any more questions. Good luck! (Please give a thumbs up, I am doing this for a summer job!)

Try your headphones in a different audio device. If the problem persists than the headphones have a split in the wiring for the left earbud. If you are under warranty then Sennheiser will happily repair your headphones.

It is likely that from ware and tare that one of the wires has come apart inside the line so it is time to buy a new pair

try using other headphones to your unit, if it plays, the problem is in the CX400 indeed. usually caused by unintentional yanking & other factors, the internal of the wires were broken, it can be fixed yes, with patience and some soldering skills, just find the appropriate cable for that particular model, with imagination you can even use other headphone cables, ;-)

Earphones are not compatable.

The phones are probably not reaching the bottom of the connection where the MP3 is told to stop sending sound to the speaker.

Test with other phones.

If the problem persists, a firmware update would be a good idea.

Cheers

YOU CAN GO TO THE MOBILE HARDWARE POINT AND SHOW THE PHONE OR EARPHONE.

plz check the sound driver. ound may be muted on ur system.

Try wiggling light switch side to side kinda hard, (the light switch is the one on the left) it should come on, showing you its a bad lt. switch.if that fails install 1 new 40watt,(long) appliance bulb. but it is going to be the switch or the bulb considering there wasn't any wiring work done on unit. part# for the light switch is 3060140 make sure the back of the switch is white not black (black is a fan switch) Good Luck !!!
