Can you actually feel music through vibration?
Why low frequencies feel different from high ones
Different receptors respond to different ranges. Pacinian corpuscles are most sensitive around 200–300 Hz, which is why mid-bass frequencies feel most physically present, while very high frequencies are barely felt at all.
Long wavelengths also travel through floors and furniture, which is why you feel a neighbour's bass and not their vocals.
What haptic feedback adds to listening
It reinforces rhythm. Timing information delivered through touch arrives on a channel that is not competing with the melody for attention, which is why a synchronised pulse makes a beat feel more defined rather than more cluttered.
It also makes music partially accessible in situations where sound is not — silent environments, or hearing loss.
The practical limit
A phone's haptic engine is small. It reproduces rhythm and emphasis well and cannot reproduce pitch or timbre in any meaningful way. Expect a felt pulse that follows the music, not a second version of the music.
