Good Voice Hearing Device Adaptation Timeline

Week 1

Initial Adjustment

  • Family Communication: If living with family, encourage them to actively turn on the controller. This helps both parties get used to wearing the device.
  • Extending the Ear: Both the user and family members should adapt to the idea that communication no longer requires speaking directly into the user's ear. The controller functions as the user’s ear.
  • Self-Voice Adaptation: Practice adjusting the speaking volume if the user's voice feels too loud.

Week 2

Becoming Familiar with Device Functions

  • Extending the Ear: When watching TV, place the controller near the TV’s audio source and adjust the left/right volume to a comfortable level. During meals, place the controller on the table or closer to the speaker to easily engage in conversations.
  • Bluetooth Streaming Feature: Pair the controller with a smartphone via Bluetooth and practice making phone or video calls with distant family members. Start using the controller for streaming videos and movies.

Week 3

Adjusting to Noisy Environments

  • Practicing in Noisy Places: Begin using the hearing aid in loud environments, such as restaurants or shopping centers. To hear conversations more clearly, habitually move the controller closer to the speaker.
  • Noise Reduction Mode: If the environment is too noisy, practice switching between Noise Reduction Mode and Enhanced Noise Reduction Mode for better clarity.

Week 4

Full Adaptation & Maintenance

  • Function Familiarity: By this stage, the user should feel comfortable operating all key functions and fully experience the benefits of the hearing aid. They can also gradually extend their daily wearing time based on their needs.
  • Charging & Maintenance: Remember to charge both the controller and earphones regularly. Turn off the device when not in use to maintain battery performance and prevent excessive discharge, which can shorten battery life.

FAQs

Please read our Support page to find out more

Can I use other bluetooth earphones with Good Voice hearing devices?

No, Good Voice hearing device uses a specialized hearing aid Bluetooth module that is not compatible with regular Bluetooth earphones.

Additionally, standard earphones have lower volume output and cannot provide the necessary sound amplification for hearing assistance.

Do Good Voice hearing devices require Wi-Fi?

No Wi-Fi setup, no extra bills. Everything is taken care of so your loved one can use their hearing devices frustration-free.

How long does the battery last?
  • Controller: Provides 10-12 hours of continuous use on a full charge.
  • Wireless Earphones: Last 6 hours per charge, with up to 15 hours total when using the charging case.

Battery life depends on volume settings—higher volumes and Bluetooth streaming will drain the battery faster. However, the current design is optimized for all-day use.

For all-day convenience, simply recharge overnight, and you're ready to go! 

How long does it take to charge? Does it support fast charging?

Both the controller and earphones take about 2 hours to fully charge.

The package includes a dual charging cable that allows you to charge both the controller and earphones simultaneously.

This device does not support fast charging. Please use the included charging accessories to ensure the best performance.

Why does the package include both wireless and wired earphones?

Good Voice hearing devices come with a specially selected wired earphone for backup use when the wireless earphones run out of battery.

💡 Tip: If you're on a Bluetooth call and want family members to listen in, just plug the wired earphones into the controller, and they can hear the conversation too!

Why can’t I hear any sound on calls or YouTube?

When using Bluetooth for calls or media streaming, volume is controlled by your phone.

  • Check if your phone is muted.
  • Adjust the volume directly from your phone.
  • For media streaming, press the Stream Button (🎵) on the controller. Once the 🎵 symbol appears on the screen, sound will switch to the streaming mode.
Why do I need both a controller and earphones? Isn’t that inconvenient?

Traditional hearing aids have both the microphone and speaker built into a small earpiece. Since these components are close together, the sound from the speaker can loop back into the microphone, creating an annoying whistling noise (feedback).

To reduce feedback, most hearing aid brands lower the overall amplification, but this can make sounds too quiet, making it harder to hear conversations. Additionally, because the microphone is placed near the ear, users may struggle to hear speech clearly if the speaker is too far away.

OKB Hearing solves this problem by separating the microphone from the earpiece. The controller acts as an extension of the ear, allowing it to be placed closer to the sound source. It also features our advanced sound processing technology, which reduces background noise and enhances speech clarity. By increasing the distance between the microphone and the earpiece, Good Voice hearing devices effectively eliminate feedback noise.

The controller also includes simple control buttons, so you can easily adjust settings without needing a complex mobile app. This makes Good Voice hearing devices more intuitive and convenient to use.
