Bluetooth Audio Delay On Speakers


Bluetooth audio delay can be incredibly irritating when watching videos or movies. It’s a common issue that many people have encountered with Bluetooth headsets, headphones, and speakers.

The sound you hear doesn’t match up with the action, word, or movement on-screen as the audio is delayed. Fortunately, there are some ways to reduce audio delay in Bluetooth connections.

You might not be able to completely eliminate it but here are a few solutions that you can try.

Factors That Affect Bluetooth Audio Delay

Bluetooth audio delay is an issue that many people face when connecting Bluetooth devices, such as headphones or speakers to their phones and laptops.

To avoid Bluetooth audio delays and other technical issues related to your Bluetooth connection, you should ensure that the codec of your Bluetooth earphones and the source device match. Let’s take a look at each of these in more detail.


When an audio file is transmitted wirelessly it needs to be converted into a format that is suitable for transmission first. This process of encoding and decoding the audio file is known as Codec.

There are many audio codecs available today, each with its own advantages and disadvantages. For instance, the newest Bluetooth audio codec — AAC — has relatively better sound quality compared to older codecs like SBC but it consumes more power than its predecessors.

Therefore, if your source device (mobile phone or computer) has a newer Bluetooth version, you should ensure that your Bluetooth earphones too use the same compatible audio codec, or else your setup will simply revert to SBC which might cause significant delays in streaming media due to its low level of compression efficiency and throughput speed.


Another cause of delay could be interference from other wireless devices operating on similar frequencies as the ones used for Bluetooth communication.

To prevent such situations, make sure all other devices are keeping their distance from your Bluetooth device otherwise you might find yourself facing severe lag issues during playback.

How To Fix Bluetooth Audio Delay

When Bluetooth first came out, it was intended as a wireless replacement for audio cables. Perfect for music or audiobooks, but as soon as you’re watching videos or gaming, it can introduce latency that makes everything look like a bad dub. No one wants that.

Bluetooth speakers and headphones will always have lag, but there are ways to minimize it. Here’s our guide to help navigate this tricky issue and make sure your video and sound are perfectly in sync with no lip-sync issues.

Bluetooth Audio Delay On Smartphones

If you’re experiencing Bluetooth audio delay on your iPhone or Android device, don’t worry — there are simple and easy solutions that you can use to correct this issue.

Reconnect Device

If you have already paired up a Bluetooth device with your phone, then all you have to do is ‘forget’ the device and reconnect it again. This simple process helps reset any applied configurations which might be responsible for the audio lag in the first place. To forget a Bluetooth device on your phone, follow these steps:

Step 1: Open the Settings app.

Step 2: Tap on Bluetooth and select your connected device from the list of detected devices.

Step 3: Select ‘Forget This Device’ and tap on Forget Device to confirm the process.

Once you’ve done this, pair up the same device again and check whether it has fixed the audio delay issue.

Minimize Interference

Interference is caused when your Bluetooth earphones receive unwanted frequency signals obstructing the clean signal between your phone and the earphones. It can occur due to various appliances like a wireless mouse, Wi-Fi connections, televisions, etc.

You will notice an audio delay only when such devices are around such as office settings or living room. If you have gadgets of this sort in close vicinity, the best way is to turn off the device that is probably causing interference.

Or, isolate these devices at a farther distance while you are using your Bluetooth earphones. While doing this can help you fix the issue, another important factor is staying within range of connectivity. 

Operate On The Right Bluetooth Codec

Earlier this article mentioned that wireless audio transmission involves encoding, decoding, compression, and other processes to send out a signal. All these are handled by an algorithm – which will provide the right sequence and methods to complete the process.

This algorithm is known as Bluetooth Codec – and it’s responsible for high-level operations such as its frequency range, bit rate, and quality of the audio transmission.

There are several Bluetooth codecs available, but some may be better than others. Depending on their features, codecs ensure different qualities of the audio output – and so you should look for device-compatible ones when shopping.

SBC is a basic audio codec that functions at low power levels, providing decent audio ideal for earphones. Higher-end devices come with aptX Low Latency or aptX HD for outstanding sound during videos or gaming sessions as well.

Restart Your Phone

If you are experiencing Bluetooth audio delay, restarting your device might help fix the issue. It might seem like an obvious solution, but, it can sometimes help remedy several system-related issues and problems on your device.

Restarting clears your system cache and resets all open programs, ensuring that all new software is installed correctly and increasing the speed of your device. Here’s how you can restart your device:

On iPhone Devices: Hold down the power button and either volume button simultaneously until the “slide to power off” screen appears. Then drag the slider to turn off the phone. Wait for a few seconds before pressing and holding down the Power button again.

On Android Devices: Press and hold down the Power button until a menu appears onscreen with multiple options displayed (e.g., Restart/Power Off/Airplane Mode). Select Restart; alternatively, press and hold down the power button until a restart option appears to confirm.

Fix Bluetooth Audio Delay On Headphones

Are you struggling with sound delay on your Bluetooth headphones? This can be very frustrating if you’re watching a movie or playing games. If you’re here looking for solutions, then let’s see and discuss what steps to take so that you can try to fix the problem.

Choosing The Right Audio Codec

Selecting the ideal codec for Bluetooth streaming from your audio source device to headphones is crucial in ensuring that you get a smooth and error-free transmission of sound.

For example, if you’re using iOS as your device, then it’s best to find a pair of headphones supporting AAC since this is Apple’s preferred codec choice.

Other devices such as Android phones offer different options such as aptX LL, aptX HD, and even manufacturer-specific ones like LDAC for Sony and Samsung’s Scalable Codec.

If you’re using any of these smartphones, pop on over to your settings app and enable them accordingly. Then make sure that whichever pair of Bluetooth headphones you buy also support them too. By taking these steps, you’ll be able to enjoy a great wireless listening experience every time.

Match The Source & Headphones’ Bluetooth Audio Profile

If you’re trying to achieve low-latency audio when listening via wireless headphones, then matching the source with your headphones’ Bluetooth audio profile is essential. That means both the source transmitting and the receiver, need to have similar Bluetooth versions and audio profiles.

Using Bluetooth 5.0 for both your source and receiver should improve audio latency significantly, so try to use devices that feature this latest standard. Understanding your current setup can help guide what you need to do next.

For example, if both your source and receiver are using the latest Bluetooth 5.0, then the connection will be utilizing Bluetooth 5.0 standards and its features such as improved bandwidth.

On the other hand, if either the source or the receiver is a version lower than 5.0 (like 4.1), while another one is new-age (like 5.0), the connection will fall back to Bluetooth 4.1’s default settings, which could reduce performance significantly

Fortunately, there are reliable dongles available in the market right now that work with Windows, Mac, and smartphones that will let you transmit audio using Bluetooth 5.0. It’s definitely worth investing in these items if you want low-latency wireless sound quality from your headphones.
