Yes. Power on S2, choose your pickup mode and short-press REC to start recording directly to its 64 GB built-in storage. Short-press REC again to stop and save. No phone, app, computer or wireless receiver is required.

Short press is the default. If you prefer, HISONG Link lets you set a 1-, 2- or 3-second hold to start.

AirStudio S2 comes in one configuration for $279, with the S2 main unit, two wireless monitoring earbuds, the Wireless Audio Receiver, a magnetic desktop stand, mounting accessories, a windscreen, a USB-C cable, a USB-C-to-USB-A adapter and a carrying case.

The Universal Wireless Audio Receiver is a different product. It is sold separately for $99 and is not included with S2.

Choose it when you want to send S2 audio to a compatible camera, mixer, speaker or PA system. It adds digital and analog output options, works with AirStudio S1 and S2, and costs US$100, sold separately.

For compatible USB-C phones, tablets and computers, start with the included Wireless Audio Receiver or a direct USB-C connection. The Universal Wireless Audio Receiver is not required for onboard recording or wireless monitoring.

Yes, with a supported DualTrack workflow. Onboard DualTrack saves your microphone audio as MIC and active backing sources together as MUSIC, with up to two tracks stored on S2. A MUSIC file is created only when a valid backing source is present.

App DualTrack records vocal and backing as up to two tracks in HISONG Link through a supported direct USB-C connection. Wireless receivers deliver one mixed stereo feed rather than separate tracks.

Stop and save your take, then connect S2 to your computer with USB-C. In HISONG Link, switch S2 to USB Drive Mode, copy your Take folders or WAV files, and open them in your DAW to continue editing.

You can also sync onboard takes to HISONG Link on a compatible phone through direct USB-C. File transfer does not use the wireless receiver. Switch back to USB Audio Interface Mode when you want to record over USB again.

Yes. S2 supports compatible iOS, Android, Windows and macOS workflows. Use direct USB-C for supported phone recording, HISONG Link and DAW workflows, or the included Wireless Audio Receiver for compatible wireless digital recording.

HISONG Link adds sound controls, supported App recording and take management. Available functions depend on your device, app and connection. Onboard recording gives you another way to capture ideas while keeping these connected workflows available.

Yes. The included wireless monitoring earbuds use HISONG ZeroSync™ for real-time, ultra-low-latency monitoring. Take them out of the S2 compartment, put them on and power on S2. You can monitor your voice even without starting a recording.

The earbuds store and charge inside S2. Use them for live monitoring; ordinary Bluetooth headphones and AirPods can introduce noticeable delay.

Yes. S2’s microphone captures vocals, speech and acoustic performances. Choose Condenser mode for detailed capture in a quieter space, or Enhanced Dynamic for more focused vocal capture around background noise.

VocalSense™ 2.0 helps reduce distracting environmental sound while preserving natural vocal detail. Voice and an acoustic instrument picked up by the same microphone remain together on the microphone track.

No. The default is 48 kHz / 24-bit. Up to 96 kHz / 32-bit float is available in supported mono microphone workflows; it is not the fixed format for every mode.

The available format depends on the recording mode, connected device and software. You can check a take’s actual format in its recording details in HISONG Link.
