MTW300, as a mid-low frequency earplug, may be disappointed for those who like to listen to very exciting music. For ordinary pop music and some musical-based music, MTW300 has a lot of low-frequency volume, and its low-frequency performance itself is better than many co-located multi-unit products.
The low frequency of MTW300 pays more attention to the high-level sense created by the looseness. This taste is exactly the characteristics brought by the carbon nanotube diaphragm unit, the dynamic range, and the stronger control force. This powerful control force will not make the amount of low frequency become loose. For instruments under high sound pressure, such as percussion instruments, MTW300 can show with a clean sound, explosive power, and full of details.
