The MedWand is engineered to capture and deliver accurate stethoscope sounds. To make the most of it:

• Use quality headphones (over-ear, in-ear, or on-ear style with low-frequency response) for clearer playback.
  - Most laptop and desktop speakers lack a frequency response low enough to properly auscultate heart sounds, which commonly range from 20Hz to 150Hz. When shopping for headphones, try to select a pair with a minimum frequency range of 20Hz (0.02kHz) or lower and a maximum frequency range of 150Hz (0.15kHz) or higher for optimal auscultation. 
  

• Ensure a snug fit so external noise is minimized.

• Recordings themselves are always unaltered, but some device “enhancements” may change how you hear them (see below). 

Example Headphones

Many operating systems include features—Dolby Atmos, sound enhancers, equalizers, UHQ upscalers—that boost volume or tweak frequency response. These do not change the underlying MedWand recording, but they can introduce distortion, mask subtle murmurs, or alter timbre in ways that make clinical interpretation harder. If you notice unexpected artifacts or muffled tones, disabling or adjusting these settings is recommended.
