What are the causes of Bluetooth latency?

Bluetooth Latency occurs due to:

• Recent changes in the operating systems of computers or mobile devices.

• Firmware changes in devices

• The bugs in the car stereo system.

• Physical objects disrupting the connection.

• Software or app updates to devices.

Now, let’s focus on how to fix these Bluetooth latency on different devices.

How can I fix Bluetooth latency?

First, try turning your Bluetooth on & off, pairing & repairing the devices connected to Bluetooth at the same time. This will cut all the devices. If this method doesn’t work out, then try the following steps regarding different devices to improve the Bluetooth connection.


Either PC or Mac, signal problem is the main cause of audio stammering. The household devices such as cordless phones, baby monitors, smart TVs & laptops all operate in the same frequency range & cause signal interference.

You can reset your router to channels with the least interference, like 2.4 & 5 GHz, to fix the signal problem. You can change the channel on the router by logging into the router’s web interface through a web browser. Go to the WiFi settings page & search for the WiFi channel. Select a new channel on the drop-down menu under WiFi channel. Also, reduce the number of active Bluetooth devices connected to your computer.

You should turn off Handoff on Mac. This feature assures seamless continuity over Mac, Apple Watch & iOS devices & allows users to continue their task started on one device on another device. Therefore, you can finalize e-mail started on your Mac on your iPhone.

Go to ‘System Preferences’ & select ‘General’. Now, deselect ‘Allow Handoff between this Mac and your iCloud devices.’ On the iPhone, go to ‘settings’, select ‘General’ & select ‘Handoff’ to disable it.

  • Once check the audio settings. Issues like computers recognising Bluetooth speaker as both speaker & headset can cause audio stammering. You should deselect the headset & enable it as a wireless speaker.

Mobile devices:-

Mobile phones are convenient for listening to music, watching movies or playing games because you can use them wherever you want. But the audio disruptions may interfere in your enjoyment. You can adopt the following steps to solve the audio latency on mobile devices.

Make sure that the Bluetooth headphones are within a certain range. Bluetooth products mostly offer a maximum of 33ft of Bluetooth signal range because they use short-wavelengths to transmit data. Therefore, the more you move away from a Bluetooth source, there will be more delay in the audio. To avoid such situations, always carry your phone with yourself or you can buy a Bluetooth headset which supports maximum range of more than 100ft.

Keep your mobile phone charged. When it’s out of charge, it will limit its performance in order to save the battery & you will experience audio latency. You can charge your phone immediately & then reconnect with your Bluetooth.

Set the performance level of your phone to high. Power-saving settings or battery saver apps limit the phone’s performance to save battery. Go to “Performance profile” or “Battery saver” option & turn it to a high performance setting, then check your Bluetooth connection.

Check your battery and settings. If they are okay, then check for interference. To reduce the signal interference, turn off Bluetooth devices not in use.

Remove the objects which are obstructing the Bluetooth signal. Even a book on your phone or a thick mobile cover can obstruct the Bluetooth signal from your phone to headphones.


You can also experience audio stuttering while pairing your mobile with the car’s audio system. Cached files on your phone may cause a problem, so clear them first. When these files are deleted, suitable files are recreated for seamless Bluetooth connection between phone and car.

If the Bluetooth is still lagging after clearing cached files, then the Bluetooth codec used by the car’s audio system is old. The most common codecs are aptX, SBS, AAC & LDAC.

The Bluetooth codec in Android can be changed but you need to enable developer options, which may be difficult for new ones. Your one mistake can damage your mobile phone. You can use USB if your cars have aptX & iPhones don’t use it. If your car has Apple or Android CarPlay, then go for Bluetooth.

Wireless headphones:-

In some instances, outdated operating systems on mobile phones can obstruct smooth Bluetooth connection. To avoid this, make sure your phone is running on the latest version of an operating system. Maybe the headphone apps could be outdated. Make sure it is also updated.

You can replace the old generation headphones with a new compatible one with your phone. In comparison to other headphones, Earbud-style headphones may experience more lagging issues like dropped calls, dropped connection between two earbuds & difficulty in syncing. Your head could also be the reason for signal interference.

For fixing syncing issues, check on the manufacturer’s website for firmware updates & troubleshooting guidelines for keeping headphones updated.

Paring your Bluetooth headphones with the number of devices can also cause lagging. In order to fix this, they delete all pairing data from the device. You can find all the resetting information in the manufacturer’s manual.

How to prevent Bluetooth latency?

Go wired:-

It is the simplest way to avoid any disturbance. You can go for wired headphones & speakers if cord clutter is not a big deal for you.

Adjusting the device’s audio delay settings:-

This feature is offered by built-in Bluetooth technology TVs. Audio delay settings on the Bluetooth menu can be adjusted to improve the Bluetooth latency.

Most of the mobile developers have counter-measure steps added into the app coding. Therefore, audio lag is rarely experienced while watching or listening to anything on a mobile.

Qualcomm’s aptX Low Latency:-

This technology works best to reduce audio lag & provides good audio quality & excellent synced visual-audio. If you are watching TV using Bluetooth headphone, this will reduce the lag at unnoticeable point. This technology can also be used while using Mac & Windows.

Bluetooth speakers having aptX Support:-

Avantree Torpedo Plus:- This includes altX LL & provides high quality streaming with less audio latency. It is affordable & suitable for tabletops & counters.

Fugoo Sport 2:- This Bluetooth speaker delivers quality audio with low latency & has a long battery life.

Marshall Stanmore II:- This Bluetooth speaker has a classic Marshall amplifier-look. It provides audio with Treble & bass knobs on top. One can tweak the sound as they see fit.

Bowers & Wilkins T7:- This Bluetooth speaker can deliver a loud sound which can be heard at all the corners of a small room.

Bluetooth headphones having aptX support:-

Bang and Olufsen Beoplay H9( third generation):- It sounds amazing and keeps the audio synced.

Avantree Aria Pro:- It offers codec support at a significant value.

Sennheiser Momentum Wireless 3:- It offers a wide-ranging codec support along with great sound & balance.


Bluetooth technology also has disadvantages such as lagging. But, you can follow the above methods to overcome Bluetooth latency. Also, try to buy devices that support low latency.
