The red input/power light is not indicating on the unit for the Thomson Wireless Headphones

Hi Anonymous, you are surely taking the signal for your wireless headphones, from the headphone output of your Bose sound system
This usually cuts the sound in the external speakers
Try to find another type of audio output for your headphones
Comment on what Bose system you have, so I would try to find a better solution
I hope you comment

Trata de buscar otro tipo de salida de audio para tus auriculares

Espero te comentario

Murdo's tip to trim off the cover of the AA battery base to expose a few mm of metal is spot on. Replacement rechargeable batteries for my Thomson wireless headphones did not charge, no green light, utterly frustrating, till I read Murdho's suggestion. Thanks for that

Blinking red light indicates that the battery can't be charged. Problem might be a worn out battery, or simply a bad connexion. First check with another charging cable and if unsuccessful then with another power adaptor. Problem could also be the plug in your headphones (this can usually be fixed in a good repair shop for 15~20$).

Hope this help

take the batteries out of it..

The red flashing indicates a low (or check) battery. The instructions on page 4 in the link below for the Plantronics Backbeat 903/906 will show you how to charge it up. On page 8 you'll see how to power down and then up the headset to reset it.

Output voltage on PS is -(negative)19 Vdc at center pin. 12 volts will work if you have the right size plug.

SImply connect the headphones to a power source. Then press up and down volume buttons at the same time. It will reset the headphones.

The following procedure will re-establish the communication link between the Headphones and the Wireless adapter, this is called "pairing". Before you start please make sure both the headphones and the wireless adapter are fully charged and turned off.
Note: The headphones and the wireless adapter come pre-paired from the factory.
1. Press and hold the power button on the headphones. See Figure 1.

Figure 1

2. Continue to hold the button down until the LED starts flashing red/blue in an alternating pattern. Release the button when the LED starts flashing red/blue. See Figure 2.

Figure 2
3. Once the headphones LED is flashing red/blue, press and hold the power button on the wireless adapter. See Figure 3.

Figure 3
4. Hold down the button until the LED starts flashing red/blue in an alternating patter. The LED will blink blue, then turn off for a few seconds then blink red/blue. Release the button when the LED starts flashing red/blue. See Figure 4.

Figure 4
5. Once both the headphones LED and the adapter LED is blinking red/blue, press the volume up button once on the headphones. See Figure 5.

Figure 5
Once the headphones is paired with the adapter, the LED on the headphones will blink blue once every two seconds. See Figure 6.

Figure 6
When the adapter is paired the LED will be solid blue. See Figure 7.

Figure 7
The adapter may continue to blink red/blue for a few seconds even after the headphones LED starting blinking blue. This is normal; the adapter may take a few additional seconds before the LED turn solid blue.
Once the headphones and the adapter are paired, it is not necessary to pair them again even if the batteries on both units are completely drained.
Additional Note: Repeated pairing will not improve the sound quality or give the headphones and the adapter a cleaner connection.

Trying re-syncing the transmitter and the headphones. Hold down the power buttons on both until they alternate red and blue blinking, worked for me and now they work just fine. Got that from the Logitech FAQ website.
