Recommended for Mild to Moderate/Severe hearing loss or standard hearing in a loud environment.

Deep insertion eartips reduce background noise and increase effectiveness of the amplified audio signal.   Eartips are not compatible with cochlear implants, but a headset (not included) may be used when residual low frequency hearing has been preserved.

Frequency filters focus on cardiac and pulmonary ranges to improve perception of heart, breath, bruit, bowel or Korotkoff sounds.

• Lungs sound range from 70 Hz up to 4000 Hz
• Heart sounds range from 20 Hz to 650 Hz

The ONE uses a rechargeable Lithium Ion battery.
