Thank you for viewing! 【Industry-First Balanced Armature Speaker!】 While most products on the market use dynamic speakers, balanced armature speakers are better suited for hearing aids due to their small size, high resolution, and low power consumption, offering clear advantages. ➊ Overwhelming high-frequency resolution. Frequency response exceeds 8 kHz, improving voice clarity by over 30%. ➋ Amazing miniaturization. The unit volume is only one-third that of dynamic types, making it lighter and more comfortable to wear. ➌ Excellent energy efficiency (impedance of 100Ω or more vs. dynamic types at 16-32Ω), reducing power consumption by approximately 40% at the same volume. ➍ Superior environmental resistance. Magnetic shielding of 80dB or more shuts out electromagnetic interference. Stable sound quality in any environment. ➎ Long-life design. No deterioration of the diaphragm over time, maintaining clear sound for a long period (lifespan of dynamic types: approximately 3 years). 【Approximately 35x Amplification & Comfortable Fit】 Equipped with the latest DSP technology, it amplifies the volume up to 35 times while reducing noise by 65%, distinguishing between human voices and surrounding sounds to improve voice clarity. Weighing only 6g and designed ergonomically, it provides a comfortable fit that is not tiring even after long hours of use. It goes behind the ear and hooks for secure placement, eliminating the worry of falling out, and is easy to use even for elderly people who are not accustomed to wearing earphones. You can enjoy comfortable hearing anytime, without discomfort or fatigue! 【Stepless Volume Adjustment & Easy Operation】 Manually scroll the volume adjustment knob up to increase the volume. Scroll down to decrease the volume. Fine-tune the volume to your preference and the surrounding environment, selecting the optimal volume to enjoy clear sound quality. The buttons are designed for ease of use for the elderly, with intuitive operation. No complicated settings are required; simply turn it on and it's ready to use. Easy to use for first-timers and the elderly. (To prevent howling and echo, turn the switch "ON" after wearing it, then turn on the power.) 【Amazing Long Battery Life! Safe for Outings & Power Remaining Display】 The rechargeable hearing aid can be used continuously for 24 hours on a single charge. 1837IN-68
