How to Fix Short Range, Static, or Audio Cutting Out

Use these steps if your wireless audio cuts in and out, sounds static or choppy, or only works at a short distance.

Step 1 – Test the Devices Close Together

Move the headphones, earbuds, or speaker close to the transmitter.
Play audio for a few minutes.
Check whether the sound becomes stable.

Sound is better when close? Distance, wireless interference, or an obstacle between the devices is likely affecting the signal. Continue to Step 2.

Step 2 – Move the Transmitter Away from Wireless Devices

When possible, keep the Avantree transmitter at least 3–5 ft / 1–1.5 m away from nearby wireless equipment.

Common sources of interference:

Wi-Fi routers and access points
Bluetooth speakers, headphones, keyboards, and mice
Smart TVs, streaming boxes, and wireless game controllers
Wireless security cameras and cordless phones
Microwave ovens and other wireless transmitters

Especially check your Wi-Fi router. Do not place the transmitter directly beside or on top of it. Bluetooth and many wireless products use the same 2.4 GHz frequency range.

Step 3 – Remove Obstacles

Keep the path between the transmitter and your headphones or speaker as open as possible.

Avoid placing the transmitter:

Behind the TV or inside a cabinet
Behind large furniture or on the floor
Next to large metal objects or other electronics

Walls, doors, metal objects, large appliances, and people between the devices can reduce wireless range. Place the transmitter in an open, elevated location when possible.

Step 4 – Turn Off Unneeded Bluetooth Devices

Temporarily turn OFF Bluetooth on nearby phones, tablets, computers, and smart TVs, then test the Avantree connection again. This helps prevent your headphones or speaker from reconnecting to another device.

Step 5 – Restart and Test Again

Turn OFF the Avantree transmitter.
Turn OFF the headphones, earbuds, or speaker.
Wait about 10 seconds.
Turn the transmitter back ON.
Turn the headphones, earbuds, or speaker back ON.
Wait for them to reconnect, then test the audio again.

How to Tell What Is Causing the Problem

Audio Is Normal Only When Close to the Transmitter

Distance, wireless interference, or physical obstacles are likely affecting the signal. Move the transmitter to a more open location and farther away from nearby wireless equipment.

Audio Cuts Out When a Microwave or Wireless Device Is Used

That nearby device is likely causing interference. Increase the distance between it and your Avantree transmitter, headphones, or speaker.

Still Having Short Range, Static, or Audio Cuts?

Before contacting Avantree Support, test the system with the devices close together. Please include your product model, approximate distance, nearby wireless equipment, and whether the problem affects every connected device or only one.
