How to Avoid Interference with Bluetooth?

November 12, 2022

Bluetooth is a popular type of wireless connection found in many devices today, but the problem occurs when something (visible or invisible) "interferes" with the Bluetooth connection, thus affecting the sense of use.

Common Signs of Bluetooth Interference Include

Hearing Static

You may occasionally hear static or buzzing sounds when other devices near you are using the 2.4GHz frequency. Worse, in addition to being annoying, constant static sounds can add unwanted noise that can affect your hearing. Static sounds occur because the activity is occurring on the same frequency, which overlaps with the connection between your devices. 

Sound Delay

When using a bluetooth device,  your audio needs to be compressed and transmitted through frequencies from the audio source to the headset speakers. Just like when you travel from one place to another, interruptions can cause delays in your expected arrival time. In the case of Bluetooth headsets, it may produce audio that sounds like it's one step behind everything else.

Connection disconnections

Bluetooth interference can cause your Bluetooth connection to disconnect intermittently. This may be due to a physical barrier preventing a reliable connection between two paired devices. When this happens, your device will disconnect and try to reconnect until the connection is successful.


There are several reasons why Bluetooth interference can occur. In addition, sometimes it can even be a combination of multiple causes. 

The Following Are Some of the Main Causes

Wireless Internet Access

Your regular Wi-Fi router uses the 2.4GHz frequency to communicate with other devices on your network. Bluetooth uses the same frequency. Therefore, Wi-Fi connections may overlap with Bluetooth and cause interference.

Microwave ovens and fluorescent lights

When operating, microwaves emit electromagnetic waves that interfere with the 2.4GHz wavelength. Just being close to a working microwave oven may cause connection loss. Fluorescent lamps have similar problems.


How to avoid Bluetooth interference and improve your connection

Remove all obstacles

Certain building materials may block weaker signals such as Bluetooth. Metal, bulletproof glass, concrete and stucco are particularly bad, and marble, stucco and brick are less likely. So if you're really struggling with interference, your first step should be to keep your Bluetooth devices away from these materials. That means no brick walls between you and your devices, and definitely no metal tables!

Stay within range limits

Most Bluetooth headsets have a range limit of 33 feet. If you are more than 33 feet away from your device, your Bluetooth connection will slowly break. To get the most out of your headset, keep the two devices close together.

However, not all headsets are limited to a range of 33 feet. You can check the range of your headset by reading the manual or contacting the manufacturer.

Stay away from microwaves and fluorescent lights

Both emit 2.4GHz frequencies, and staying away from them will keep you away from the source.

While these interventions will certainly help, they are not actually needed. That's because technology has evolved to the point where interference shouldn't be a big problem. If your problem persists, then you may have a problem with one of your Bluetooth devices and you should take it to an expert.
