Speak privately.
Anywhere.
A refined acoustic wearable that traps voice sound waves at the mouth. Conduct confidential calls, speak with voice AI, and converse without anyone nearby hearing your speech.
Your voice stays inside.
Multi-layer acoustic dampening traps speech sound waves before they radiate into the room. Speak at conversational volume with zero leakage to the person standing beside you.
Continuous fresh circulation.
Bladeless micro-turbine delivers smooth fresh air without buffeting internal microphones or making annoying fan noise. Wear for hours in total comfort.
Private calls in public spaces.
Engineered with hypoallergenic liquid silicone, close-proximity MEMS microphones, and 18-hour continuous battery life.
Speaking in public
is awkward and distracting.
Whether taking an urgent client call, dictating notes to voice AI, or speaking on a quiet train, you run into two immediate problems:
No Speech Privacy
People sitting next to you overhear confidential work details, personal thoughts, and client metrics.
Disturbing People Nearby
Speaking aloud on quiet trains, airport departure gates, and shared desks annoys and distracts people around you.
An acoustic chamber
for your voice.
NullWave traps your voice sound waves at the source. Talk naturally at your normal volume without sound escaping into the public space.
Complete Voice Privacy
Soft internal acoustic foam absorbs your speech before sound can leak out into the room.
Studio-Quality Voice Pickup
Microphones positioned right at your lips catch your speech clearly while locking out cafe chatter.
Continuous Fresh Airflow
Silent bladeless air circulation prevents heat and stuffiness with zero motor noise or mic buffeting.
Voice stays inside. People nearby hear nothing.
Soft medical silicone for hours of zero-pressure wear.
USB-C fast charge. 15 minutes gives 5 hours.
Continuous fresh air without fan noise.
Designed for everyday comfort.
Silent Airflow
Bladeless micro-impeller circulates fresh air quietly with less than 14 dB sound.
Lip-Level Clarity
Close microphones pick up your voice with crystal clarity while blocking environmental noise.
Soft Silicone Seal
Medical liquid silicone conforms naturally to your facial structure without skin redness.
18-Hour Battery
High-density battery with USB-C quick charge gives 5 hours of talk time in 15 minutes.
Why headphones don't
protect your privacy.
Noise-cancelling headphones only protect what you hear. They do nothing to stop others from hearing your private conversations. NullWave traps your speech right where it starts.
