How can I switch between TV watching and live conversations with SMARTO?
If you have paired SMARTO to a TV or other Bluetooth device simply press the red “hang-up call” button on SMARTO to pause the audio stream. After a few seconds the LED will shine yellow to indicate that you are in Personal Hearing mode. To switch back to the streamed audio press the green “answer call” button on SMARTO. The LED will shine in blue to indicate the Bluetooth is active.
Is it possible for others to hear the TV while I am using my BeHear headset?
This depends on how you are using your BeHear ACCESS, and your specific TV.
- If you are using BeHear in Personal Hearing mode to amplify nearby important sounds, others will be able to hear the TV as well.
- If you are using BeHear as a Bluetooth receiver, paired with your television, others will probably not be able to hear the TV. However, if your television (or set top box) supports simultaneous sound output to optic/RCA/3.5mm and the TV speakers, we have a recommendation for a workaround (see below).
If your television doesn’t support Bluetooth, or if it doesn’t support dual audio output when a Bluetooth device is connected, we recommend using a Bluetooth transmitter, such as our HearLink PLUS, to enable the television audio to be transmitted to both your BeHear headset and the TV speakers.
In any event, you should check your television manual for information about Bluetooth connections and dual audio output.
BeHear PROXY isn’t connecting automatically with the TV transmitter.
The HearLink PLUS is programmed to save power by entering sleep mode if a paired Bluetooth device (such as the BeHear headset) has been disconnected for more than 10 minutes.
To “wake up” HearLink PLUS and re-establish the connection with the headset:
- Press and hold the HearLink PLUS power button for 3 seconds to turn it OFF.
- Then, press and hold the HearLink PLUS power button for 2 seconds to turn it back ON.
Can I mute the TV sound in my headset using the headset buttons?
If you are using the HearLink PLUS Bluetooth transmitter to stream the television audio to your BeHear headset, the answer is yes.
A quick press on the middle button of the headset (left-hand side for NOW or ACCESS, right-hand side for PROXY) will mute the TV audio. Another quick press on the same button will unmute the sound. [Note that television audio is muted automatically if you receive a call to a smartphone that is paired to the headset (in parallel to the HearLink PLUS connection). Once you either reject or terminate the call the TV audio will resume automatically.]
If the television has built-in Bluetooth support, allowing you to connect your BeHear headset directly to it, you may also be able to mute and unmute the TV audio stream from the headset, as described in the previous paragraph. Consult the TV’s technical documentation.
My TV doesn’t have Bluetooth. Can I still use BeHear PROXY to listen to it?
For best results the television audio should be streamed to BeHear PROXY using Bluetooth. If your TV doesn’t support Bluetooth we recommend purchasing the HearLink PLUS transmitter which will connect to your television’s (or set top box’s) optical or analog output port and transmit the audio via Bluetooth to the BeHear PROXY neck speaker.
What is the difference in the TV listening system with personal amplifier vs. just the amplifier?
Using one of the BeHear headsets on its own in Personal Hearing mode will pick up sound from the television and amplify it according to your hearing profile (if you have performed the Hearing Assessment in our W&H BeHear app to personalize the device). This may be sufficient for your needs.
However, the benefit of the HearLink (or HearLink PLUS) transmitter is that it captures the TV audio and transmits it directly to the personalized headset, eliminating distractions (such as room reverberation, and ambient noise).
Additionally, since your headset can pair simultaneously with two Bluetooth devices, if you receive a phone call on your paired mobile phone while watching television the TV audio will be muted automatically, and then resume once you disconnect the call.
What range can I expect with the BeHear headset + HearLink PLUS combination?
The operational distance for the HearLink PLUS paired with a BeHear NOW or BeHear ACCESS is up to ~200ft (~60m).
If you are interested in a more detailed explanation, keep reading.
The BeHear NOW and BeHear ACCESS headsets are Bluetooth Class II devices, while the HearLink PLUS is a Bluetooth Class I device.
- A Bluetooth link between two devices is always bi-directional. The actual range depends on radio performance of the transmitter and the receiver on the both sides.
- The difference between Class I and Class II Bluetooth devices in radio transmitting power is 16dB (Class I – 20dBm, Class II – 4dBm). Consequently, the power transmitted by a Class I device is ~40 times greater than that of a Class II device (10^(16/10)). The distance is a function of the square root of the power, meaning that the distance can be increased by ~6 times (SQR(40)) from 10m for Class II to 60m for Class I.
- In addition, a Class I device has improved receiver sensitivity (by ~4dB), which leads to an increased distance of ~1.5 times. Consequently, typical distance for Class I is 100m vs. 10m for Class II.
- When a Class I device is connected to a Class II headset the expected distance is as follows:
a. From a Class I transmitter to a Class II receiver – up to 60m (see paragraph #2)
b. From a Class II transmitter to Class I receiver – up to 15m (see paragraph #3)
c. For a bi-directional it is ~15m, based on the shortest range of #a and #b.
- HearLink PLUS as a Class I device provides additional improvements because of its dual-antenna design. The major effect is for the receiving part, since transmitting power is limited according to the standard. For communication with a Class II receiver, like our BeHear headsets, the distance is increased significantly because of this improvement.
There is no TV audio sound in my headset when I use HearLink PLUS.
Try the following:
- 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.
- Verify that the HearLink PLUS transmitter is in TX mode and that the TX indicator is lit.
- 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.
- 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.
Connecting the HearLink TV transmitter blocks the television audio for the rest of the viewers.
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.
I cannot find an audio output jack for the HearLink on my television.
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.
How is HearLink PLUS different from other audio transmitters?
There are many audio transmitters on the market, but HearLink PLUS has some unique features that set it apart as the transmitter of choice for assistive hearing.
- It supports ListenThrough™ technology to allow important ambient sounds (like a conversation with a TV viewing partner, or the doorbell) to pass through on top of the streamed audio.
- During incoming phone calls the audio stream will be stopped and then automatically resumed when the call is completed.
- It supports up to two BeHear® headsets simultaneously.
If I’m using HearLink PLUS can anyone else hear the TV?
This depends on your specific TV. Some televisions support dual audio output, which would allow you to define one output for HearLink PLUS and a different one for the TV speakers, while others do not. Check your television manual for details.
