Frequently Asked Questions
How does NullWave stop people from hearing my voice?
NullWave has special sound-absorbing acoustic materials inside the mask. When you speak, the sound waves are trapped inside rather than spreading into the room, so people sitting right next to you cannot hear what you are saying.
Will my voice sound muffled on phone calls?
No. High-quality microphones inside the mask are positioned directly near your mouth to capture your voice in crystal-clear quality, while outside sensors block background noise from your call.
Does the mask get hot or stuffy while wearing?
No. A quiet, bladeless airflow system continuously brings in fresh, cool air to keep you comfortable without making any noise on your microphone.
Is it comfortable for long calls?
Yes. NullWave is made with soft, medical-grade silicone and flexible ear loops, weighing just 88 grams for zero-pressure, all-day comfort.
