Please send a message before purchasing. 8-level fine volume adjustment & up to 40dB amplification. Easy operation with a single button, a hearing amplifier that cuts noise with Digital Signal Processing (DSP) technology. No complicated operations are required. Just take it out of the case → use it → put it back. That's it in just 3 steps. Taking it out of the charging case automatically turns it on in 8 seconds (with voice guidance). When finished, simply put it back in the case, and it automatically turns off and starts charging. A gentle green light illuminates while the hearing amplifier is charging and turns off when charging is complete. The main unit lasts up to 15 hours on a single charge, so you don't have to worry about running out of battery during the day, from morning to night. The dedicated charging case (580mAh) allows for an additional 4-5 full charges. The remaining charge of the charging case is clear at a glance with a digital display, and charging is simple with the Type-C port.
