What range can I expect with the BeHear headset + HearLink PLUS combination?
The BeHear NOW and BeHear ACCESS headsets are Bluetooth Class II devices, while the HearLink PLUS is a Bluetooth Class I device. As a result, you many wonder what kind of transmission range you can expect with this product combination. Here is a detailed explanation:
- 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. According to experimental data the operational distance for the HearLink PLUS and a BeHear NOW or BeHear ACCESS: up to ~60m (~200ft).
What kind of range can I expect from a BeHear headset when used with the HearLink PLUS transmitter?
The Bluetooth version in BeHear headsets is v. 4.2 and in the HearLink PLUS it is v. 5. However, the range depends on the class of the Bluetooth device (Class I or Class II) rather than on its version (v. 4.2 or v. 5). BeHear are Class II devices while HearLink PLUS are Class I. Operation range between these two devices is larger than for two Class II devices (10m or 40ft) though less than for two Class I devices (100m or 400ft). We expect that for the BeHear + HearLink PLUS combination you can get a 20m or 80ft range, in open spaces.
My BeHear headset is not pairing with my laptop computer.
Make sure that the Bluetooth option on your computer is set to “on”. This option is usually found in the “Settings” section, “Bluetooth and Other Devices” sub-section.
On Windows computers you can quickly access the Bluetooth settings from the action center in the system tray.
If you don’t see the Bluetooth icon here it may be an indication that Bluetooth is not active. In this case, go to the computer Settings → Devices and make sure the Bluetooth switch is ON. If it is not, slide it to the right to activate Bluetooth.
What can I do when my HearLink transmitter loses connection with my BeHear headset?
First, verify that you are within Bluetooth range (~10 feet, 3.5 meters for HearLink; ~200 feet, 60 meters for HearLink PLUS).
If that is not the issue, and a long time has passed between uses, or if the smartphone has been playing an audio stream, the headset may not automatically reconnect with the HearLink or HearLink PLUS transmitter when you are within range. In this case, a short press on the headset’s Power button should re-establish the connection with the transmitter.
Can I use my BeHear headset to hear audio from my laptop computer?
Depending on the application, BeHear may appear either as a headset or as a headphone, just like most other Bluetooth headphones.
For most music players it will be listed as a “headphone” while for messaging services, such as Skype/Viber/WeChat etc., it will be listed as a “headset”.
For each additional Bluetooth device you would like to link to the BeHear headset you will need to perform the pairing procedure (placing the headset into “Pairing Mode” by turning it OFF, and then pressing the power button for several seconds until the LED flashes red/blue). You should see the BeHear headset in the “Audio Devices” section of the Bluetooth pairing screen.

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. Many set top boxes (cable boxes) have an analog audio output jack and/or an optical (digital) audio output jack. If you connect the HearLink/HearLink PLUS TV transmitter directly to the set top box the audio may transmit simultaneously to the BeHear headset and the television speakers.
I cannot find an audio output jack for the HearLink on my television.
Can I connect BeHear to my tablet?
Sure! BeHear products connect to practically any Bluetooth-supported device (such as an iPad, music player, or other tablet) to stream audio directly to your headset. For tips on connecting multiple Bluetooth devices to your headset see this video (for BeHear NOW) and this video (for BeHear ACCESS).
The app’s Home menu button is grayed out.
A grayed-out Home button indicates that the headset is not connected to the app. Go to Settings->Connection and verify that the headset is in the Paired Devices list. If you don’t see the BeHear device in the list you’ll need to pair it — see the video links below for instructions.
When the headset is connected properly a checkmark will appear. If there is no checkmark, tap the name of the headset in the list of Paired devices to re-connect the headset. Another way to reinstate the connection is with a short press on the headset’s Power button. For more information about pairing your headset with the app, watch these videos:
