NTT Sonority brought the ‘SonoVo Stick’ to Japan as a clip-on microphone built to keep speech understandable in noise above 100dB. Designed for construction crews and event staff who need both hands free, it uses two microphones with ‘Magic Focus Voice’ to prioritize the wearer’s voice over machinery or crowd noise.
A magnetic clip keeps the 29 g unit on clothing, and the push-to-talk button remains usable with work gloves. It is sold in Japan for ¥24,000 through a purchasing inquiry form, and it remains a microphone rather than a full headset.
NTT Sonority shows how Japan sales through an inquiry form can keep the SonoVo Stick aimed at business buyers instead of casual audio shoppers, while voice capture that still works past 100dB turns it into a coordination tool for loud worksites and venue floors, where missed instructions can slow jobs or disrupt service.

Why This Trend Is Growing
- Noise-proof Wearables
- Compact audio devices with advanced voice isolation create new possibilities for safer communication in construction, logistics, and live-event environments.
- Hands-free Worksite Communication
- Wearable push-to-talk tools are reshaping how frontline teams coordinate in high-noise settings without interrupting manual tasks.
- Business-only Audio Hardware
- Inquiry-based sales models position specialized communication devices as enterprise tools rather than consumer accessories, enabling more targeted adoption pathways.
Industries Being Reshaped
- Construction Technology
- High-noise voice capture supports more reliable coordination across job sites where machinery, distance, and protective gear complicate communication.
- Event Operations
- Venue teams gain value from compact microphones that preserve speech clarity amid crowds, music, and production equipment.
- Industrial Safety
- Speech-focused wearables introduce new layers of operational awareness for hazardous workplaces where missed instructions can increase risk.
