ION TelesoundsTelevisions never exactly had great-sounding speakers, and today’s TVs are thinner than ever before. Which means their speakers are smaller and worse-sounding than ever before. Simply connect the wireless transmitter to your unit’s optical or Aux input and the audio is sent by digital wireless directly to the ION headphones. No cords, no wires, no fumbling. Just clear, rich, high-definition sound. This article answers some popular questions about the features and functionality of the ION Audio Telesounds.

How long does the battery last? How long do my Telesounds need to charge?

Your Telesounds' battery should last approximately 10 hours on a 6 hours charge with the proper rechargeable 2 AAA batteries (included). If your Telesounds' battery is low you will notice the battery indicator flashing on the LCD screen.

For best results, we recommend charging the Telesounds headphones for at least 6 hours before the first use.


What is the difference between the Coaxial, Optical, and RCA cable?

Because there are so many different TVs available, the Telesounds comes with a few different options for you to get connected. 

  1. RCA -  This cable is the most common and popular setup for all users. An RCA cable carries an analog audio signal which makes it easy to use, but it could degrade the sound of high-quality digital recordings. 

  2. Coaxial -  This is a common type of digital audio cable, and can deliver 5.1 surround sound audio, just as an Optical cable. Typically used to connect a subwoofer to an audio receiver. The difference in sound quality between a digital coaxial and an optical cable is nearly indistinguishable.

  3. Optical -  This cable is the least common of the three input options on your Telesounds. The Optical cable is a great solution with minimal signal degradation of sound, but may not be available on all TVs. It can deliver up to 5.1 surround sound. 


How do I pair Telesounds to my Television?

To set up the transmitter with your TV (or other sound sources):

  1. Using the included power adapter, connect the transmitter’s power input to a power outlet. 
  2. Connect one of the transmitter’s Audio In connectors to an audio output on your TV:

    • To use the TV’s RCA stereo outputs, use the RCA-to-RCA cable to connect them to the transmitter’s RCA (Right & Left) inputs
    • To use the TV’s optical (digital) output, use the optical cable to connect it to the transmitter’s Optical input
    • To use the TV’s coaxial output, use the coaxial cable to connect it to the transmitter’s Coaxial input

  3. Set the source switch to the type of connection you made in Step 2:

    • If you connected to the transmitter’s RCA (Right & Left) inputs, select Audio.
    • If you connected to the transmitter’s Optical input, select Optical. The Optical/ Coaxial light on the front of the transmitter will turn red.
    • If you connected to the transmitter’s Coaxial input, select Coaxial. The Optical/ Coaxial light on the front of the transmitter will turn red.

      See our description above for more information about each connection type. 

To set up the headphones with the transmitter:

  1. After setting up the transmitter, set the Power switch on the transmitter to On.
  2. Turn on the headphone by pressing and holding the Power button for 2 seconds till you see the red light.
  3. Wait a few seconds for the headphones and transmitter to connect wirelessly to the transmitter. When properly connected, the light on the headphones will be green


The volume of the TV controls the volume of the headphones. Is this normal?

Your TV may have an audio output setting in its menus that lets you choose between a fixed output or a variable output. If this is the case, we recommend using the fixed output.

  • When using a fixed output, the TV’s volume level cannot be changed by its volume controls; you must use the –/+ buttons on the headphones to adjust the volume.
  • When using a variable output, you can change the TV’s volume level by using its volume controls, but the sound in the headphones may be too quiet. 


Will the Telesounds be able to charge my 3rd party rechargeable AAA batteries?

The Telesounds includes (2) AAA rechargeable batteries for the headphones. These can be charged regularly with the included charger. 

Alternatively, you can use standard NiMH rechargeable batteries or alkaline batteries, but they will not charge when you place the headphones on the charging dock.


Is it possible to order proper replacement batteries for my Telesounds directly through ION Audio?

Yes, if necessary, replacement batteries for the Telesounds can be ordered direct from ION Audio. Contact ION Audio’s parts department at


Should I power my Telesounds OFF while charging?

Yes. We recommend powering OFF the Telesounds for the most effective charge.

To fully power OFF, press and hold the Power button for two seconds. Once powered off and charging, the display will show the current time and the battery icon flashing to indicate charging. Above the USB port, the battery indicator light will illuminate while charging and go out once the headphones have been fully charged.


What does the color LED light represent on my ION Audio Telesounds?

This light indicates the status of the headphones:

  • Red: The headphones are powered on but not connected wirelessly to the transmitter.
  • Flashing red: The headphones are low on battery power. To charge them, place the headband of the headphones on the charging dock on top of the transmitter (make sure that the transmitter is connected to a power outlet and that its Power switch is set to On).
  • Green: The headphones are powered on and connected wirelessly to the transmitter.
  • Off: When the headphones are charging on the transmitter, the light will turn off when they are fully charged. When the headphones are not charging and powered off, the light will be off.


What do I do if the sound in the headphones is distorted or clipping?

Check that the volume on your sound source is at an audible level. If you are connected to a TV, receiver, DVD player or hi-fi system, make sure that the Att. switch on the transmitter's rear panel is set to -8dB.


The optical/coaxial light is flashing. What do I do?

Make sure the included optical cable is securely connected to both the Optical input on the transmitter’s rear panel and the optical output of your sound source (TV, receiver, etc.).
