Describe:
1. Rechargeable case charging: Your hearing aids can be charged using the detachable charging case. (You'll need to charge the detachable charging case first.) It's portable, and it saves you the hassle of constantly buying a coin cell battery.
2. Charging time: charging for 4-6 hours, it can work for 20 hours, the indicator light is red when charging. Turns off when fully charged. (For removable charging case)
3. Especially designed for the hearing-impaired, more fitting to the ear canal. No pain even when worn for a long time.
4. If the earmuffs are not fully inserted into the ear canal or air leaks from the earmuffs, it will cause an annoying whistle. We offer 3 different sizes of ear tips to reduce whistling and noise.
