What is NeiSa?

NeiSa brings the vivid sound of a home theater to your headphones and earbuds.

Through neural spatial audio modeling, NeiSa simulates an entire home theater system.

Relive that spine-tingling moment of theater surround sound — anytime, on the go.

01MOBILE HOME THEATER

NeiSa is a mobile home theater

Carry your speakers, amplifier, and processor in your pocket.
An entire home theater, completed in chipset-embedded software.

Building a home theater takes real money, real space, and a complicated setup — eight speakers placed at precise angles, every channel tested one by one.

NeiSa is a home theater you carry in your pocket.

Speakers, amplifier, processor, cables — every piece of equipment is simulated with neural spatial audio modeling. A complete home theater, realized on a single micro chip.

02GETTING STARTED

All you need is a NeiSa-equipped device and headphones

Connect your headphones through a NeiSa chipset or device, and ordinary stereo transforms into home theater surround in real time.

03FOR FPS GAMERS

EX-STEREO vs. 7.1 Spatial Audio

If you are an FPS player who has spent years learning positional cues in stereo and simply want to widen that same image, choose EX-STEREO rather than 7.1.

When a stereo source — not a multichannel source — is sent through a NeiSa chipset or device, connecting as 7.1 maps the sound that belongs at your sides into a 60° span directly in front of you. The sound image narrows, and the positional cues no longer match what you hear in stereo.

Standard stereo ±90° span  vs  7.1 front stereo ±30° (–45°) span

For movies, drama, and variety content, hearing the mix from the front feels natural, so 7.1 spatial audio works well. It is competitive FPS play — where you have trained on stereo positioning for years — that benefits from EX-STEREO.

UX continuity: to extend the stereo experience you already know, we recommend EX-STEREO mode. EX-STEREO is sometimes labeled FPS mode.
