NTT Launches SonoVo Stick: A 29g Wearable Microphone Built for Extreme 100dB Noise Environments

NTT Debuts the SonoVo Stick Wearable Microphone

NTT Sonority has officially commenced sales of its specialized wearable communication device, the SonoVo Stick, in Japan. Priced at ¥24,000 (roughly $150) excluding tax, the gadget targets industrial settings, factories, and loud event spaces where standard hands-free communication fails. The device is currently available through a purchasing inquiry form rather than direct retail.

Weighing just 29 grams, the SonoVo Stick attaches magnetically to clothing and pairs via Bluetooth 5.3. It relies on a dual-MEMS microphone setup alongside NTT's proprietary Magic Focus Voice technology, utilizing directional beamforming and advanced filtering to separate human speech from heavy background sound. According to the manufacturer, the system maintains clear audio in environments surpassing 100dB, featuring three distinct modes for handheld use, hands-free clothing attachment, and broader environmental sound capture.

Designed with professional workflows in mind, the hardware includes an IP54 dust and splash resistance rating, USB-C charging, and a battery life reaching up to 15 hours. A physical push-to-talk button accommodates gloved hands for walkie-talkie style operation. The unit also integrates with communication apps like BONX WORK and LINE WORKS, alongside the SonoVo AI platform for processing recorded dialogue. Note that the product is a standalone microphone rather than a full headset, requiring users to plug in wired headphones via a 3.5mm jack.

Should you buy it? The SonoVo Stick suits professionals working in exceptionally loud industrial zones who need reliable, hands-free speech isolation. Compared to standard consumer wireless earbuds, its specialized noise-filtering algorithms and glove-friendly controls make it a niche enterprise tool rather than a daily multimedia accessory.
