2. Check for Interference

Interference refers to unwanted frequency signals that hijack and disrupt the clean signal between your source and Bluetooth headphones. Your wireless mouse, WiFi connection, television, and other similar appliances and gadgets emitting radio frequency could negatively impact the signal flow to your Bluetooth headphones, resulting in sound delays.

Theres also a maximum distance you can get away from the audio source before you start losing connection and experience choppiness in what youre listening to. And its not just about the range your headphones can handle.

While most Bluetooth headphones can now go as far as 10m on average, walls and other similar forms of physical blockage can prevent you from enjoying the headphones full range.

To resolve Bluetooth issues, place the devices near each other, avoiding Wi-Fi routers and microwaves that may cause interference. You can also disable Bluetooth on unused gadgets to cover all bases.

3. Pick the Right Audio Codec

Bluetooth codecs compress digital audio for efficient transmission, reducing file size and bandwidth usage, then decode it into audible signals.

Different Bluetooth audio codecs compress and transmit audio uniquely. This results in different transmission qualities some codecs are prone to audio delays, some are not.

While its great to have headphones that support high-quality audio codecs, your headphones should match the codec of your audio source. If not, they will revert to the lowest audio codec SBC, which is the most prone to audio delays.

For example, youll have the best wireless listening experience for iOS if your headphones support the AAC codec, as its Apples codec of choice. For Android, aptX LL and aptX HD are your best options if your headphones support them.

To change the Bluetooth audio codec on Android, follow these steps:

1. Open Settings, then navigate to About phone > Software information.
2. Tap Build number seven times, then enter your phone lock password to enable Developer mode.
3. Return to the main Settings menu, then select Developer options.

Why Do My Bluetooth Headphones Have a Delay?

Bluetooth headphones often have trouble with audio delay compared to wired ones due to the way they transmit audio.

In a wired connection, audio latency is usually between 5-10 milliseconds. For Bluetooth, delay times vary from 34 milliseconds with aptX Low Latency to 100-300 milliseconds for most wireless earbuds and headphones.

Bluetooth requires time to encode, transmit, and decode the audio data sent from the source device (like your smartphone or computer) to your headphones. This process, although typically fast, can result in a noticeable delay between the audio you hear and the corresponding video or game action.

This process is also limited by Bluetooths bandwidth. The bigger the audio signals file size (higher quality equates to larger audio files), the more bandwidth it needs to get to the receiver.

Think of bandwidth as the size of the road while the audio file size is the amount of traffic. If the traffic exceeds what the road size can accommodate, traffic jams will happen, reducing movement to a slow crawl (more time required to complete the transmission).

However, while wired connections have lower audio latency, Bluetooth headphone users dont always experience noticeable delays. Factors like the Bluetooth version, codec, interference, and settings can influence this.

Frequently Asked Questions
