The mic likely requires professional service.

get new earphones those are cheap or you can adjust the head phone volume in the ipod or iphone in setings

If you are using Nickel-Metal Hydride, rechargeable batteries, they are not designed to hold a charge for a week---just a couple of days if that. They are meant to be continuously charged or when charged, used immediately; best use for cameras/flash.

You should be able to hook the tv to the cable box the cable box should have your A/V jacks. If so unplug the PS3 plug in your receiver to the cable box and run the PS3 through the receiver. Also check the side of the tv for HDMI inputs if you have HMDI you can go to Radio Shack and get a converter to go from HDMI into A/V

Never used them, but distorted outputs indicates you are over-driving them, connected them to 'speaker out' rather than 'headphone out', Or you have already blown the drivers. Connect to a different sound source and see how they work then. You likely will not get a loud boom from any headset.

need more information.what model?handheld or beltpack? microphone or instrument?check transmitter and receiver are set to same frequency.does a different transmitter work with the receiver?does the receiver show the transmitter is functioning (ie receiving rf) but not receiving audio signal (af)?

No, finding spares for Headphones is difficult since they are all different, it's not the same as cabinets or speakers. You are better off buying a new pair and keeping your old ones as a spare.

you might check to make sure that your gain isnt to high many times this can negatively effect your sound quality

They must be selected to be on the same channel. Usually a color code indicates a matched set.

You could try super gluing on another tip or something that is the same size as the original tip and use that as a button.

Hi Cathy.. it sounds like you might be connected to the wrong jacks instead of the output that the headphones need. Most high quality stereo headphones have a single 1/4" stereo plug that would readily plug into a 1/4" jack on the front of the stereo labeled "PHONES" or HEADPHONES". Many lower quality "computer headphones" or headsets have two 1/8" plugs. One is often black or red and is for an included microphone that may be a boom type (shown below) connected to one of the speakers or an "in-line" type built into the cord itself. The headphone speakers in the headset get their signal from the other plug - which is usually green; but could be any color really. There should be 3 metal parts on the stereo headphone plug. The tip, the middle ring and the bottom ring. Many times the mic is mono (not stereo) and only has only a tip and a bottom ring on the plug. You can see stereo headphone and microphone plugs he picture below:Computer Headphones or "Headset" with mic and phone plugs.Your Yamaha stereo will probably NOT have 1/8" jacks to directly plug the headphone into. You can buy an adapter that you would plug your headphones into and then plug the adapter into the 1/4" jack on the stereo. One is pictured below: Front and rear views of a "1/4" to 1/8" Stereo Adapter Plug" The front plugs into the stereo and the the smaller 1/8" headphones plug into the rear.I hope this helps & good luck!

I think this is common problem for headphones. To fix it you will have to solder cord's wires back to plug. If you have tools and some experience you'll be fine

Hi,

Often the rubber button is pushed into the microphone.
You can easily disasemble the unit.
Just open the batterycase, you will find some small torx screws.

probably ..they discharged to the max..and this way the connection was reset...If they are still functional ..you have to pair them again with the transmitter... and will work again ...If they work ..avoid in the future to discharge them totally ...
To pair they usually have a button that have to be pressed and will blink until picks up the signal ..or take a look in the manual to see the exact procedure for this model ..

Hello
Provide the model number of your Sennheiser Headphone please. Without it, it is not possible to place a solution to this problem. Provide the details to me by Fixya. OK.

One is for left, one for right, and one for ground...the usual color code is right=red, left=white, and ground = bare wire(or some other color)

It appears that the 238 has a cable connected to one headphone only.
If this is the case, try your existing cable.
If both ends look identical and plug into your music player easily, you could try any audio cable with
3.5mm mini plugs on each end.

I have used such to drive low powered speakers, and discount the hype about audio cables.

If you look on eBay, entering "sennheiser hd cable", a number of sellers have cables, none specifically claimed to fit.
The cheapest among the first few entries advising the cable has a 3.5mm plug at one end and a 2.5 mm plug at the other. If my first suggestion is unworkable, this will probably work.

Alternatively you could try to find one locally, to test for fit before purchase.

Check the other sellers for a look at pictures and possibly details if I got it wrong at the start and your cable has 2 connectors at one end.

If all else fails, take your headphones to you local electronics supplier, get plugs that fit and get a good friend with a soldering iron to make you up a cable.

Sennheiser normally have a 2 year warranty on their products.

My Sennheiser HDR 140 headphones charge whenever you hang them on the charger. The charger will "trickle" charge them to keep the batteries fully charged. If you find when you use it the batteries discharge quickly it's time to replace them.
My batteries are about 2 years old and I still get about 8-10 hrs of use before needing to recharge
