No battery replacement required. 【3g Ultra-Lightweight Design, Comfortable Fit】 The hearing aid was born from ear shape data, with an ultra-lightweight design of only 3g, significantly reducing the burden on the ears, and zero pressure on the ears even with continuous long-term wear. Ergonomic design gently wraps around the ear canal and won't fall off during cooking, walking, or shopping. The discreet design reduces psychological resistance when using it.
