Which operating system does the W&H BeHear smartphone app support?

The W&H BeHear smartphone application supports both Android (from version 4.4 and up) and iOS (from version 9 and up).

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:

  1. 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.
  2. 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.
  3. 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.
  4. 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.
  5. 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.

What latency (delay) do your TV transmitters achieve?

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

Which Bluetooth headsets support the aptX codec?

The current versions of both our headsets (BeHear NOW and BeHear ACCESS) support both the Qualcomm aptX “classic” and aptX-LL (low latency) codecs.

How is the telecoil response related to the microphone response in BeHear ACCESS?

  1. The BeHear ACCESS headset is calibrated with a standard inductive loop transmitter as per the ANSI S3.22-2009 standard.
  2. Signal levels can be adjusted based on the current environment using the headset’s volume control (either manually or via the free app we provide for iOS and Android smartphones).

How long will the BeHear ACCESS battery last?

  • in “hearing mode”: 13+ hours
  • for phone use: 10+ hours
  • for music play: 8+ hours
  • typical battery lifespan: ~3 years

Notes:

  • A full charge takes 2-3 hours.
  • After 600 charging cycles the battery will continue to function, but usage time may be reduced between charges.

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.

  1. 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.
  2. During incoming phone calls the audio stream will be stopped and then automatically resumed when the call is completed.
  3. It supports up to two BeHear® headsets simultaneously.

What comes in the BeHear NOW box?

The box includes a headset, a USB charging cable, a travel pouch, three types of silicon ear tips in different sizes, three pairs of ear hooks in varying sizes, 2 pairs of wind protection covers, and a printed Quick Start Guide.

 

How long will the BeHear NOW battery last?

  • in “hearing mode”: 12+ hours
  • for phone use: 10+ hours
  • for music play: 8+ hours
  • in standby mode: ~600 hours

Notes:

  • A full charge takes 2-3 hours.
  • After 600 charging cycles the battery will continue to function, but usage time may be reduced between charges.
