How to replace the battery in HDR 45 headphone

If you twist the earpiece,one of them has two NIMH AAA batteries ,worth checking out if these are gone ,which is what happened to me.I was about to bin my rs130's and just stuck two new rechargeables and the earphones are working again!!!!!

As for $20 dollars from sennheiser for replacements!?!?!?
You should pick up two NIMH batteries for a couple of bucks on ebay or amazon.DO NOT USE ORDINARY BATTERIES!!!!!

You can download the manual for the product from the below link:

Hope that allows you to resolve the issue. Please revert back for any further assistance.

The headphones will automatically charge wirelessly when placed in the cradle that should have come with the package. To make sure the headphones are placed correctly, a red light should illuminate letting you know they are being charged and are properly placed.

check on radio shack

The batteries are at end-of-life OR your charger has failed.

Forst replace the batteries... they are MOST likely bad. Charge the new ones before using.

Twist the pad counterclockwise on the left earpice. You'll find the batteries underneath.

I had complete silence on an HDR 130 headset (no beeps, nothing), but I solved this problem using a solution posted on another thread. Unplug the base, take out the batteries and wait 30 seconds. Reconnect it all and listen. Mine started working immediately!

You can get a replacement plug at any good electronics parts supplier. Check this site out for help on how to do the replacement:http://www.metacafe.com/watch/1045725/how_to_solder_how_to_repair_headphones/
