Use the hearing aid feature for social gatherings, watching TV, and the Bluetooth feature to take calls and listen to music or any other audio from your phone, serving as a bridge between you and the world. * 【Rechargeable Hearing Aids】Fully charge in 2 hours. The hearing aid can operate for 30 hours without Bluetooth connection and 20 hours with Bluetooth mode, typically lasting 3-4 days with normal use. You can also check the remaining battery life on your phone. The hearing aid provides voice prompts for volume adjustments and low battery alerts, informing you of the current volume level or when it needs charging. * 【Less Feedback】These hearing aid uses the latest American DSP digital Bluetooth 5.2 chip.
