Why does my Bluetooth speaker keep skipping?

Bluetooth wireless speakers provide a convenient way to stream audio from smartphones, tablets, and computers without being tethered by wires. However, a common frustration many users experience is intermittent skipping or glitching in the audio playback over Bluetooth.

This skipping can have a variety of causes, ranging from interference to low batteries. Troubleshooting and understanding the source of the issue is key to resolving it. With a few strategic fixes, it’s often possible to eliminate Bluetooth speaker skipping and ensure smooth, uninterrupted audio streaming.

Interference

Interference from other devices is a common cause of Bluetooth speakers skipping or cutting out. This is because Bluetooth and Wi-Fi operate on the same 2.4 GHz frequency band, which can lead to interference between the radio signals (https://smallbusiness.chron.com/signal-interference-issues-bluetooth-technology-58273.html). Having multiple Bluetooth devices connected nearby can also cause interference as they compete for bandwidth on that crowded spectrum. Additionally, physical obstructions or even just distance between your speaker and audio source device can degrade the Bluetooth signal. Electromagnetic interference (EMI) from other electronics like microwaves, baby monitors, cordless phones, and fluorescent lights can also disrupt Bluetooth connections.

To reduce interference, try moving your speaker and paired device closer together with fewer obstructions between them. Also consider turning off other nearby wireless devices like Wi-Fi when using your Bluetooth speaker to lessen competing signals in the area. If possible, move further away from potential sources of EMI like microwave ovens and cordless phones when streaming audio over Bluetooth.

Distance and Obstructions

The effective range between Bluetooth devices depends on the Bluetooth class and can be anywhere from more than a kilometer down to less than a meter, according to Bluetooth.com. For example, Bluetooth Class 1 has a range of around 100 meters, while Bluetooth Class 2 has a shorter range of 10 meters.

The maximum Bluetooth range also depends on whether there are obstacles or obstructions between the two devices. Walls, furniture, and even human bodies can interfere with and degrade the Bluetooth signal. Thicker walls and multiple obstructions will diminish the range further compared to open spaces. According to Nordic Semiconductor, the Bluetooth range for Class 2 devices is around 10 meters indoors and up to 100 meters outdoors and line-of-sight.

Therefore, having obstructions like walls between your Bluetooth speaker and the source device can explain shorter Bluetooth ranges of just 10-30 feet indoors. To maximize range, make sure there is a clear line-of-sight between your speaker and phone or other paired device.

Paired Device Issues

One common cause of Bluetooth speaker skipping is problems with the device that is paired to the speaker. Issues like the Bluetooth being disabled, improper pairing, interference, or corrupted settings on the phone can prevent a solid Bluetooth connection.

To troubleshoot, first ensure Bluetooth is enabled on your phone and other devices. Go into your phone’s Bluetooth settings and carefully re-pair the speaker, following the steps to fully connect and sync the devices. Also check that you don’t have multiple devices connected that could be causing interference.

You may need to delete the speaker from your phone’s paired devices list and re-pair from scratch. This clears out any corrupted Bluetooth connection data. Consult your phone and speaker manuals for the proper pairing and setup process. Also try restarting both devices after pairing to refresh the connection.

Additionally, check for OS or firmware updates for your phone and speaker. Installing the latest software can resolve Bluetooth bugs that may be causing skipping issues.

As a last resort, you can try resetting your phone’s network settings to wipe all Bluetooth connections. Just be sure to re-pair all devices afterwards.

If the issues persist between one specific phone and speaker, the problem may be device-specific and require further troubleshooting of potential hardware or software issues on that phone.

speaker Hardware Issues

Bluetooth speaker hardware issues like defects, faulty antenna, or low battery can also cause skipping or audio cutouts. Some common hardware problems include:

Speaker defects: Manufacturing defects in the speaker components like the drivers, amplifiers, or circuitry can lead to distortion, buzzing, or intermittent sound. This tends to happen more with cheaper speakers that lack quality control.

Faulty antenna: The Bluetooth antenna inside the speaker receives the wireless signal from your phone or device. A broken or disconnected antenna results in a weak signal, which leads to skipping and cutouts as packets of audio data are lost.

Low battery: When the rechargeable battery in a Bluetooth speaker starts to wear out and can no longer hold a full charge, it may cause power fluctuations or sudden shutdowns mid-stream. Fully recharging the speaker before use can help, but an old battery may need replacing. Source

Checking for physical damage, trying a battery reset, or contacting the manufacturer about potential defects are good troubleshooting steps for hardware-related Bluetooth issues.

Software and Firmware

Outdated software and firmware can often be the cause of Bluetooth speaker connectivity issues and skipping. As new software and firmware versions are released, they contain updates to improve compatibility, fix bugs, and optimize performance. However, if the speaker’s firmware or the paired device’s Bluetooth software is outdated, problems like skipping may start to occur.

Try updating both the speaker’s firmware and the paired device’s operating system or Bluetooth software. Refer to the speaker manual or manufacturer website for instructions on performing firmware updates. For the paired device, make sure to install the latest OS update from the manufacturer. According to posts on Reddit, firmware updates can sometimes require multiple attempts, factory resets, reinstalls, and cache clearing before successfully completing.

If the firmware update fails or is unavailable for your speaker model, you may need to contact the manufacturer, as recommended by Soundcore’s support article here. As a last resort, you can perform a factory reset on the speaker or disable and re-enable its Bluetooth connection.

Audio Codec Compatibility

One of the most common reasons a Bluetooth speaker skips is incompatible audio codecs between the source device and the speaker. Bluetooth supports a variety of audio codecs that balance audio quality with data compression and bandwidth. Some popular codecs include SBC, AAC, aptX, and aptX HD.

However, not all devices and speakers support the same codecs. For example, Apple devices like iPhones use AAC while many Android devices use aptX. If the source and speaker don’t share a common codec, they will revert back to the basic SBC codec, which can sometimes struggle with bandwidth and cause audio skips or lag.

To avoid codec incompatibility, first check which codecs your source device supports, then find a Bluetooth speaker that supports those same codecs. High end speakers that support multiple codecs like aptX and AAC will have the most compatibility. You can also try forcing certain codecs in your device’s developer settings if available.

Signal Strength

One potential cause of Bluetooth audio skipping is a weak Bluetooth signal between your speaker and the source device. The effective range of Bluetooth technology is approximately 10 meters or 33 feet, though obstructions like walls can further reduce this. To maintain a stable audio connection, you want your speaker and device to be within this range without major barriers blocking the signal.

You can check the strength of your Bluetooth connection on both Android and iOS devices. On Android, apps like Bluetooth Signal Meter display the signal strength in dBm units. The closer to 0 dBm, the stronger the signal. On an iPhone, you can go to Settings > Bluetooth and view the signal bars next to connected devices. Make sure you have at least 2-3 bars for robust audio.

For Windows devices, you can check signal strength by option-clicking the Bluetooth icon and hovering over the device. You can also use the get-bluetoothdevice PowerShell command. Look for an RSSI value above -60 for a good connection. If your signal strength is consistently low, try moving devices closer together or removing obstructions.

Troubleshooting Tips

Here are some step-by-step troubleshooting tips to try if your Bluetooth speaker keeps skipping:

1. Check interference and obstructions

Make sure your Bluetooth speaker and paired device have a clear line of sight and are away from potential sources of interference like microwaves, cordless phones, WiFi routers, etc. Bring devices into the same room and within 30 feet of each other if possible.

2. Adjust Bluetooth settings

On your phone or paired device, turn Bluetooth off and back on again. Unpair and forget the device, then repair it. Limit the number of apps using Bluetooth at the same time. [1]

3. Update firmware and software
