You can use the BeHear headset to listen to the TV even without the HearLink PLUS transmitter, but HearLink PLUS will provide better sound quality, as the audio will be streamed directly to the headset.

If you have a set top box you may be able to use it to bypass the television’s audio output jack and solve this problem. Many set top boxes (cable boxes) have an analog audio output jack and/or an optical (digital) audio output jack. By connecting the HearLink PLUS TV transmitter directly to the set top box the audio may transmit simultaneously to the BeHear headset and the television speakers, allowing both the BeHear wearer and the other viewers to hear the audio.

If you have a set top box you can use it instead, as many set top boxes (cable boxes) have an analog audio output jack and/or an optical (digital) audio output jack. In this case, connect the HearLink/HearLink PLUS TV transmitter directly to the audio output jack on the set top box.

The HearLink PLUS Bluetooth transmitter (using the aptX-LL CODEC) achieves low latency of only 40ms, avoiding lip sync issues.

Check these possible causes :

1. One of the headsets is out of range. The quality of the Bluetooth connection (and associated audio distortions) depends on the weakest connection of the two connected headsets. For example, audio distortions may be heard by the wearer of the headset closest to the HearLink/HearLink PLUS transmitter when the second headset is out of the transmitter’s range.
2. One of the headsets is not a BeHear headset. The active CODEC (SBC, aptX or aptX-LL) for the HearLink PLUS transmitter is determined according to the common denominator for the both headsets. Two BeHear headsets will always operate in aptX-LL mode. However, if one of the connected headsets is not a BeHear headset, and it doesn’t support aptX, both headsets will work in the lower quality SBC mode only.
3. Each headset is paired to a different mobile phone. It is not recommended to connect two headsets simultaneously to one HearLink PLUS and maintain separate smartphone connections for each headset. This is due to problems which may arise when the wearer desires to switch the audio stream between his/her phone and HearLink PLUS (e.g., for an incoming call from one of the phones).

Try the following:

1. Check the HearLink PLUS panel and make sure the OPT or AUX indicator is lit. If neither is lit, make sure the power and output cables are connected securely.
2. Verify that the HearLink PLUS transmitter is in TX mode and that the TX indicator is lit.
3. Either the A or B indicator on the HearLink PLUS panel should be lit. If it’s not, it’s a sign that the headset is not connected. Press the ON/OFF button once (short press) and check again. If one of the A/B indicators lights up, then the transmitter has connected to the headset successfully. You should now hear sound in the headset.
4. If you still don’t hear sound, turn up the volume on the TV itself (or by using the BeHear headset’s left-hand side volume control).

If the TV sound is unclear or distorted, try turning ListenThrough mode OFF, or reducing the transparency of ambient sounds via the ListenThrough microphones using the headset’s right-hand volume button.
