【Easy Operation with Smart Auto ON/OFF Function】 No complicated operations are required. This hearing aid is designed to automatically turn on 8 seconds after being taken out of the charging case and placed in the ear, and automatically turn off and start charging when returned to the case. The orange lamp lights up while the hearing aid is charging and turns off when fully charged. The remaining charge of the charging case is clearly visible with a green digital display. There is no need to press troublesome operation buttons, realizing a simple and intuitive user experience. *Please be careful not to cover the microphone hole when using (to prevent howling). Manual power ON/OFF is also possible by pressing and holding for 3 seconds. 【One-Touch Volume Adjustment, Amplification up to 35dB】 This hearing aid is designed for easy operation, even for the elderly. The volume can be adjusted in 4 levels by simply pressing the volume adjustment button, and you can check the current volume level by the number of beeps. We recommend starting with the minimum volume. Equipped with a high-sensitivity noise-canceling chip, it reduces noise while amplifying sound up to 35dB, freeing you from the difficulty of hearing loud TV sounds and conversations with family, and improving your quality of life. Designed for those with mild to moderate hearing loss. 【Please Read Before Purchasing】 Regarding the characteristics of hearing aids, "selective amplification" is not possible, so environmental sounds (vehicle noise/wind noise/everyday sounds, etc.) will also be amplified, not just conversational voices. Please use it in a quiet room. This characteristic is a common structural feature of all hearing aids. 【Amazing Long-Lasting Operation! Peace of Mind Even When Out and About】 The hearing aid can be used continuously for 20-30 hours on a full charge, so you can use it all day long with peace of mind. The lamp lights up while charging. It automatically turns off when fully charged, so you can see the charging status at a glance. Furthermore, the included 1200mAh large-capacity charging case can provide an additional 200 hours of charging! You don't have to worry about running out of battery when you're out and about. The remaining charge of the charging case can be checked immediately with a green digital display, so you don't have to worry about sudden battery drain. Comes with a Type-C charging cable! No troublesome battery replacement is required. 【Only 3.5g! Ultra-Lightweight Design】 Achieves a feather-light feel. Ultra-lightweight design at 3.5g.
