Learn the multiple possible reasons why your Bluetooth headphones keep cutting out, and all the ways you can troubleshoot the issue. Anyone who's ever owned a pair of Bluetooth headphones or speakers has likely experienced audio stutters. It's that choppy way that audio cuts in and out while you're listening to music or watching videos. At the very least, it can be jarring to the senses. But with constant repetition, it can be downright rage-inducing. Not to worry - we’ve come up with a comprehensive list of possible causes for Bluetooth audio dropouts in your devices. We’ve also compiled some easy, straightforward ways to troubleshoot the issue, so let’s get to it! Common Reasons Why Bluetooth Headphones Keep Cutting Out Bluetooth technology has been around for more than 20 years. So how is it that after all these years of innovation, Bluetooth is still so problematic? The bulk of the issue lies in the fact that Bluetooth operates on the 2.4 GHz ISM band. The ISM radio bands were originally meant to be used for industrial, scientific, and medical (ISM) purposes. This includes industrial heating, induction or microwave heating, medical imaging (MRI and ultrasound), among many others. The ISM frequencies are unregulated, and an FCC license isn’t needed to operate a device on them. This makes it exceptionally appealing to manufacturers. That’s why these frequencies are overloaded with all sorts of devices. Other reasons why your Bluetooth headphones keep cutting out can also include: Interference issues. As explained earlier, many devices share the same frequency bands as Bluetooth. And all of which can cause problems with your connection. But aside from the mentioned gadgets, one of the more common reasons for interferences is your Wi-Fi router. Wi-Fi routers use the exact same frequencies as Bluetooth - 2.4-2.5 GHz. Since they use the same network, a considerable amount of crosstalk can occur between the devices. This can negatively impact how your Bluetooth headphones receive data. Ultimately, leading to audio skips or disconnections when on a call or listening to music. Interestingly, another cause for signal interference is something called cross-body interference. This can sometimes occur for those who use Bluetooth earbuds or AirPods. For example, if you have your left earbud in and your phone in your right pocket or vice versa, you may experience some audio stutters. This happens because Bluetooth signals cannot travel through water. Their range is drastically reduced to mere inches when doing so. Since the human body is 70% water, it can affect your Bluetooth connection and cause an audio stutter. Too much distance from the audio source. The farther you are from an audio source, the weaker the connection gets. Bluetooth devices fall under one of three classes - Class 1, 2, or 3. These classes are distinguished by the length of their connection range, which are as follows: Class 1: 40-100 meters (130-330 ft) Class 2: 15-30 meters (50-100 ft) Class 3: 5-10 meters (16-33 ft) Internet problems when streaming. If you’re listening to music through online streaming apps like Spotify, the quality of your internet connection will likely cause audio stutters. Slow, laggy connections prevent the app from pre-loading enough audio data to ensure smooth playback. As a result, your music will continuously be buffering, leading to audio stutters. Low headphones battery. Contrary to popular belief, Bluetooth actually has little impact on your battery life. However, if you’ve been using your headphones for a while and haven’t charged, you may notice audio stutters as the battery becomes more depleted. Headphones and device mismatch. Audio stutters can happen due to hardware and software conflicts between devices. These are often related to: Bluetooth versions. The latest Bluetooth versions (4 and above) are generally backward-compatible with Bluetooth 3 and 4. But if you try pairing it with a Bluetooth 2 or 3 device, you may run into some problems with software incompatibility that will affect your audio. For example, headphones using the A2DP profile may experience audio stutters because of differing clock speeds in a source device (your phone) and a peripheral device (your headphones). A good algorithm can correct this by making subtle adjustments to speed up or slow down the sample consumption rate so that no data packets are missed. Yet, if your device uses an older algorithm, it won’t be able to do this as efficiently, resulting in audio stutters. Bluetooth audio codecs. Audio codecs are responsible for compressing and encoding audio data for transmission. Both receiving and transmitting devices should support the same codecs for the seamless transfer of audio data. In other words, if your smartphone and headphones don’t speak the same codec language, you’re likely to experience audio issues. To learn more about this, check out our in-depth article on the different Bluetooth audio codecs and how they function. Headphones defect. Sometimes, what we perceive to be connection issues may be caused by a faulty pair of headphones. To rule out this possibility, try connecting them to different audio sources. See if the problem persists. If this is the case, it's best to try to fix the problem first. For that, check out our ultimate guide in fixing broken headphones. Audio source problems. Lastly, audio stutters can occur because of problems with the audio source itself. There are several reasons for this, but some of the more common ones are: Too many apps running. When streaming music from a smartphone or tablet, having too many apps open can be a problem. Some of these apps could be interfering with your Bluetooth connection by trying to pair with it. And others may be bogging down your phone’s system with background app activity. Updates needed. If you’re experiencing audio stutters while listening to music on a PC or Mac, your Bluetooth drivers are likely faulty or outdated. If your computer’s just undergone a system update, it’s also possible that necessary Bluetooth driver files may have gotten lost or moved in the process and need reinstalling. Audio enhancements. Some devices come with audio enhancement features designed to improve our listening experience. In some cases, this feature ends up causing problems because the headphones can’t process the additional sound adjustments. As a result, you get audio stuttering or distortion. How to Fix Bluetooth Audio Stutters There are several ways to address choppy Bluetooth audio. Some of them involve quick physical fixes, while others require simple software tweaks. But before anything else, make sure you’ve already done basic troubleshooting. Do basic troubleshooting. Before scouring the web for all sorts of troubleshooting methods, make sure you’ve covered the basic ones first. Some basic techniques involve resetting your Bluetooth device, ‘forgetting’ and re-pairing devices, or checking if devices are paired correctly. Here’s how to do them: Turn the Bluetooth off and on again. Sometimes, a soft reset is all it takes to work out an issue. Simply turn off the Bluetooth function for a couple of minutes, then turn it back on and see if there are any changes to your audio. ‘Forget’ and reconnect your Bluetooth headphones. Some Bluetooth connections may need refreshing, especially when they’re connected to a source device that’s paired with a lot of other peripheral devices. This can easily be done by going into your Bluetooth settings and selecting ‘Forget’ under the device options. Once that’s done, just re-pair your headphones and see if that does away with an audio stutter. Reset your Bluetooth headphones. In addition to resetting your Bluetooth connection, you can try resetting your headphones too, which is as simple as holding down the power button. Not all headphones can be reset in this way. Luckily, we’ve got a detailed compilation on how to reset Bluetooth headphones depending on what brand they are. Also, check if the headphones keep flashing red and blue lights. This means that the Bluetooth headphones are turning into pairing mode, even when you're already connected with a device. In that case, check out our guide on what to do when Bluetooth headphones blink red and blue. Check the battery of both devices. Earlier, we talked about how low battery levels can affect the audio quality and cause audio skips. To avoid this, make sure both your headphones and the device they’re connected to are at least 30% charged for a seamless Bluetooth connection. Change locations to avoid interferences. As previously mentioned, audio stutters can occur in areas where there’s high Wi-Fi usage or because of cross-body interference. Since Wi-Fi routers all operate on the same frequency as Bluetooth, you can definitely expect some interference. You can remedy this by resetting your phone’s Wi-Fi connection or by simply moving away from the Wi-Fi access point to a less congested area. To see if cross-body interference is causing the audio stutter, change up your devices’ position. Having a direct line of sight between devices will likely fix the problem. Stay within your headphones’ signal range. We talked about how most mobile devices are Class 2 or 3 Bluetooth devices, which means they work best over short distances. Manufacturers typically include the Bluetooth specs of their devices on the box packaging or user manual. So, be sure to double-check what those specs are and, as much as possible, stay within your device’s recommended distance. Close all background apps or software. Having multiple apps open at the same time can clutter your system. This can interfere with your Bluetooth connection, causing audio issues. It can happen more if those apps are trying to access the Bluetooth function. Some devices will allow you to limit the number of apps that can run simultaneously to help manage this. If you don’t have that option, just shut down any apps you don’t need and see...
