Why can’t I find the S1 via Bluetooth?

Purpose of this page: If your phone cannot find HISONG S1 Bluetooth in the Bluetooth device list, please check the following 4 steps in order. In most cases, the issue can be resolved in Steps 1–2.

 

Step 1｜Is the S1 powered on and has battery power?

  • Set the S1 side switch to Enhanced Dynamic mode [Middle] or Condenser mode [Right]
  • The [Left] position means the device is powered off
  • Check whether the indicator light is on
If the indicator light does not turn on:
  • The battery may be depleted
  • Charge the S1 for 1–2 minutes, then try again

 

Step 2｜Is “Bluetooth Accompaniment” turned off in the HISONG Link app?

  • Open the HISONG Link app
  • Go to the Tuning page
  • Check the Bluetooth (Bluetooth Accompaniment) toggle in the top-right corner
  • Make sure it is turned ON
 
 
 
If it was previously turned off:
  • The S1 will not broadcast Bluetooth audio
  • Your phone will not be able to find HISONG S1 Bluetooth
After turning it on:
  • The S1 will resume broadcasting Bluetooth audio and automatically reconnect to HISONG S1 Bluetooth
  • HISONG S1 Bluetooth will appear again in your phone’s Bluetooth device list

Step 3｜Are you using “HISONG Link App + USB-C”?

This is normal system behavior, not a malfunction.
If you are currently:
  • Using the HISONG Link App, and
  • Have a USB-C cable connected
The system will automatically:
  • Switch to wired USB audio transmission
  • Disable Bluetooth audio broadcasting
  • Keep Bluetooth only for app control
What you will observe:
  • HISONG S1 Bluetooth does not appear in your phone’s Bluetooth list
  • Other phones also cannot discover the device
How to resolve (choose based on your needs):
  • If you need Bluetooth accompaniment / Bluetooth connection:
    • Close the HISONG Link App or unplug the USB-C cable
  • If you need stable recording or tuning:
    • Keep the USB-C wired connection and continue using the app

 

Step 4｜Has the Bluetooth discoverable time expired?

 The S1’s Bluetooth is not always discoverable.
  • After powering on, it can be discovered by new devices for about 3 minutes
  • If no connection is made within this time, Bluetooth will automatically stop broadcasting
How to resolve:
  • Power off the S1 (set the side switch to [Left])
  • Wait 5 seconds
  • Power it on again (set the switch to [Middle] or [Right])
  • Turn on Bluetooth on your phone and search again

 

Still can’t find it? Try these two steps

Restart the device

  • Set the side switch to OFF [Left]
  • Wait 5 seconds
  • Set the side switch to Enhanced Dynamic mode [Middle] or Condenser mode [Right]

 

Restore factory settings (only if necessary)

If you have confirmed that:
  • The device has battery power
  • No USB cable is connected
  • The app is not open
  • The S1 still cannot be found by any phone
 

 

Additional notes (for understanding)

On the HISONG AirStudio S1, Bluetooth is used only for:
  • Providing third-party accompaniment audio during creation, filming, or recording (music, backing tracks, reference audio played from the phone)
Bluetooth is not used for:
  • Main audio recording transmission
  • Audio input for live streaming or filming
  • High-quality audio connection with a DAW
Therefore:
  • When using USB + the app,
  • The system will automatically disable Bluetooth audio
This is intentional, to ensure more stable accompaniment with lower latency.
