Ultra-Discreet Hearing Amplifier

The Jinghao JH-A490 is a completely-in-ear hearing amplifier measuring 2.3x1.2cm and weighing 2g. It provides up to 108dB max output across a 290Hz-4500Hz frequency range for mild-to-moderate hearing loss. The rechargeable design delivers 16 hours of use per charge with a portable case storing 60 hours total. Red and blue colour coding identifies left and right units.

Ear Canal Fit Check

Verify your ear canals can accommodate the 2.3x1.2x0.9cm in-the-ear body comfortably for extended wear. The package includes 12 ear tips across three sizes and two shapes to help you find a secure seal that minimises feedback whistling. Ensure you can operate the single-button volume and mode controls or have assistance available for adjustments.

Daily Wear Integration

The charging case provides 60 hours of backup power and fully recharges the units in 2 hours, removing the need for disposable button batteries. Memory recall retains your last volume and programme settings between sessions. Cleaning tools are included for daily maintenance of the nearly invisible devices during regular everyday use.

Which colour version should I choose?

The JH-A490 is supplied as a red-and-blue pair; one unit is red and the other blue so you can distinguish left from right.
