HellBlocker is the Heavys active noise cancellation system. It combines passive noise isolation with mild ANC to reduce outside distractions while maintaining natural sound quality.
HellBlocker works best against steady background noise such as:
- Airplane engines
- Fans
- Road noise
- Air conditioning
Sudden or changing sounds such as speech, alarms, and keyboard clicks may still be audible.
