How to open battery compartment in tdk noise reducing headset

Here is a how to video to open up the earpiece and replace the battery if needed. While you have the earpiece open you can check the the battery with a volt meter to see if it's holding a charge. The stock battery for this earpiece is 3.7v and 195mAh.

The JVC HA-NC250s are a new version of their previous model 100, and JVC claims that they will cancel up to 85% of ambient noise, coupled with better sound. In this case, JVC claims up to 16.5 db reduction at 150 kHz. These on-the-ear headphones are very lightweight at 5.3 ounces and are extremely comfortable. The head band has a reasonable amount of sliding expansion for bigger heads, and the oblong ear pieces themselves rotate and fold flat for storage. JVC uses memory foam on the earpieces, as well as double housing, for extra noise isolation. The earpieces have 40 mm neodymium drivers, which are the same size and type that the Creative Aurvanas offer.The JVC HA-NC250 noise canceling headphones. Note the ear-cushion instruction tab that explains how to replace the hidden battery.

The NC250s come in a semi-rigid black case with a dual airline-plug adapter, a mini-to-RCA phono plug adapter and a 4' detachable headphone cord. JVC includes one AAA battery, which should last approximately 50 hours. A simple sliding switch on the right side turns the noise reduction on along with a small red LED. Learning how to add the battery to the headphones required that I study JVC's user manual. The process involves having to remove the earpiece covering to get to the battery compartment, which isn't at all obvious.

Use a handsfree to confirm once again that the EARPIECE is faulty. If you are able to open and check the earpiece then remove and check the sensitivity using a AA 1.5 Volt cell. If the noise is not heard well then the earpiece must be replaced. Also check for blocked ports of the earpiece panel /dust filter which can reduce the sound.

It would depend on what headset you actually purchased. You say CS60 but it may be the Plantronics CS50 or CS55 headset. The headsets are not interchangeable. If you are not sure what headset you have, simply look on the bottom of the base for the part number. On the headset you can read what part number that is by very carefully looking under the battery. Here is a link to open the battery.

Here is a link to the CS60 instructions to replace the battery.

I think that if the base and the headset are the same it might be that you may need to subscribe or pair it together again.

This model headset is one of the headsets rated as compatible with your phone. You want to make sure there are no other bluetooth applications interfering with the link. Disconnect the phone battery, if possible, for a few seconds and reconnect. Then re-pair following the instructions on the link for the Plantronics M100 bluetooth headset.

A lot of times just taking the battery out of your phone for about 30 seconds will fix the problem. (If your battery is removable from your phone).

Hi Josh,

there may be a battery or an internal antenna failure on your headset.

You might try re-pairing the devices if you can.

connect ur headset n decrease it

It sounds like it may be a defective unit in that the charging points on the base and the earpiece are making intermittant contact, hence the clicking noise you get when the unit goes into headset mode and the fact that the battery never reaches a fully charged status.

A couple of things to try:

• Check the charging points/contacts on the base and the earpiece for damage.
• If they look ok, gently clean them with some spirits and try again.
