Description
Everyday listening with adjustable quiet
The TOZO NC9 Pro V.2022 delivers true wireless audio with hybrid active noise cancelling, an open-ear transparency option, and call-focused noise treatment you can refine from your phone.
How the three-layer hybrid ANC works
An outward-facing microphone samples external noise and generates opposing anti-noise. A second, inward-facing microphone listens inside the ear canal for another cancellation pass. Ear caps are engineered to keep a large share of outside noise from reaching the canal—materials reference up to about 90% blocked from entering the canal.
Calls and hear-through
During phone use, onboard processing filters the call microphone path to cut wind and environmental clutter so your voice comes through more clearly. Transparency mode feeds ambient sound in, useful for transit announcements or quick chats without removing either earpiece.
