Digital BTE Hearing Amplifier
The Jinghao JH-D59 is a behind-the-ear digital hearing amplifier designed for everyday listening support. It uses adaptive active noise cancellation to reduce ambient sound in real time. A portable charging case stores the device and supplies extra power. Three eartip sizes are included for a secure fit on either ear.
Users seeking simple daily amplification
This model suits people who want one-button mode switching between Normal, Noisy, Indoor and Telephone settings. The device remembers the last used mode and volume level. It is not for buyers who require Bluetooth streaming, smartphone app control or clinical-grade audiologist programming.
110 dB maximum output
The high-frequency average OSPL90 reaches 110 dB ±4 dB, setting the upper limit of amplification this unit can deliver. The amplifier runs on a 3.7 V internal battery and the case charges from a 5.0 V source. Buyers needing higher peak output or different voltage compatibility should consider other options.
