Fox 40 Sonik Blast CMG Pealess Whistle
The loudest whistle Fox 40 makes. A 120 dB pealess blast with a Cushioned Mouth Grip, built to cut through crowd noise and never fail.
Why It Works
Built to Be Heard Above Everything
The Sonik Blast delivers the most powerful sound in the Fox 40 lineup — a piercing blast that cuts through crowd noise, arena echo, and outdoor chaos instantly.
No pea. No moving parts. No clogging. The 2-chamber pealess design works in rain, cold, mud, salt water — and self-clears when submerged. Reliable every time.
The patented Cushioned Mouth Grip (CMG) is soft thermoplastic that protects teeth, improves bite security, and keeps the whistle in place no matter how hard you're working.
The harder you blow, the louder it gets. The Sonik Blast is the most efficient whistle in its class — you can't force too much air through it or cause distortion.
Used by officials in the NFL, NBA, NCAA, and international competition. When the stakes are highest, professionals choose the Sonik Blast.
Available in 11 solid colours and 8 two-tone combinations — so you can match your team colours, your league's requirements, or your own preference.
