You listen to music or you talk on the phone, and suddenly Xiaomi headphones start to intermittently play sound โ it disappears bass, we talk in jerks, then the sound is completely cut off for a second. The problem is familiar to many owners of wireless headphones brand, but it is not always clear what is the problem: whether the gadget is to blame, or smartphone, or microwave interference. In this article, we will examine all the possible causes of stuttering โ from banal to hidden defects โ and give specific solutions for each situation.
Important: stuttering can manifest itself in many ways, sometimes it's barely noticeable micropause in sound, sometimes it's a complete "split" of audio into high and low frequencies, and in severe cases, the headphones generally turn off and reconnect every 5 seconds. We'll look at all scenarios, including the rare cases where the problem lies in the firmware of a Bluetooth smartphone module or even in the physical wear of the headphone battery.
Don't rush to bring your device to the service: 80 percent of the time, you can solve the problem yourself in 10 to 15 minutes, and let's start with the simplest.
1. interference from other wireless devices
The most common cause of stuttering is external interference at the 2.4 GHz frequency that Bluetooth uses, and the fact is that this range is crammed to the limit: Wi-Fi routers, microwave ovens, baby monitors, wireless mice and even some smart home lamps, if there are several of these devices around, they create a channel conflict, and the headphones begin to slow down.
How do you check? Turn on your headphones and put them in different sources of interference.
- ๐ถ Wi-Fi router (especially if it works) 802.11b/g)
- ๐ณ Microwave (even switched off but connected to the network)
- ๐ฑ๏ธ Wireless keyboard/mouse (especially cheap models)
- ๐ก Smart lamps (e.g. Xiaomi Yeelight or Philips Hue)
If the stutter gets worse near one of these devices, the problem is the interference.
- ๐ Reboot the router and reconnect the headphones.
- ๐ฑ Switch your smartphone to 5GHz Wi-Fi (if it supports).
- ๐ซ Disable unnecessary Bluetooth devices (fitness bracelets, speakers).
- ๐ Increase the distance between the headphones and the source of interference.
๐ก
If you have a router that supports Wi-Fi 6, turn on the mode AX โ It automatically selects the least loaded channels, reducing interference to Bluetooth.
2. Bluetooth problems on a smartphone
Sometimes it's not the gadget itself that's to blame, but the Bluetooth module of the smartphone.
- ๐ฑ Outdated firmware (bugs in Bluetooth drivers).
- ๐๏ธ Module's cluttered cache.
- ๐ Energy saving mode that limits the operation of Bluetooth.
- ๐ Conflict with other connected devices.
How to diagnose:
- Connect your headphones to another smartphone (preferably the same model), and if you don't stutter, your phone is a problem.
- Check out Bluetooth version: On Android: Settings โ The phone. โ Bluetooth version. On iPhone: Settings โ Mainstream โ About this device. โ Bluetooth models.
Decisions:
Clear the Bluetooth cache in Settings โ Annexes โ Show it all. โ Bluetooth โ Memory. โ Clear the cache
Turn off power saving mode for Bluetooth in Settings โ Battery. โ Energy conservation โ Additionally.
Update the firmware of the smartphone to the latest version
Reset network settings (Settings โ System โ Reset โ Reset Wi-Fi, mobile network and Bluetooth)
Remove all paired devices and connect the headphones again-->
โ ๏ธ Note: Some Xiaomi smartphones (e.g. Redmi Note) 10/11) There's a Bluetooth bug. 5.2, It's a way for headphones to stutter when you're in active Wi-Fi, and the solution is to turn off Wi-Fi Direct in your network settings.
3. Low-charge headphone battery
If the headphone charge level drops below 20โ30%, the Bluetooth controller starts saving energy, which leads to microslowdowns in data transfer.In some models (for example, Xiaomi AirDots Pro 2 or Buddy). B100) This is manifested as a cyclical stuttering every 5-10 seconds.
How to check:
- ๐ Check the charge level in the Mi Home or Xiaomi Wear app.
- ๐ In some headphones, the charge is displayed by voice when connected (for example, โBattery 15%ยป).
- ๐ Connect the headphones to charging and check if the stuttering disappears.
Decisions:
- ๐ Charge your headphones to 100% and check again.
- ๐ Reset the battery meter: completely discharge the headphones (before switching off), then charge up to 100% without interruptions.
- ๐ง Check the contacts of the charging case - sometimes they oxidize, and the headphones do not charge properly.
| Model headphones | Minimum charge for stable operation | Typical symptoms with low charge |
|---|---|---|
| Xiaomi AirDots (1st generation) | 30% | Permanent communication breakdowns |
| Redmi Buds 3 Pro | 25% | Stuttering + distortion |
| Xiaomi Buds 4 | 20% | Lags in bass playback |
| Haylou GT1 Pro | 15% | Automatic shutdown |
Low charge.|Near the Wi-Fi router|With an active microphone|Transportation.|Don't stutter.-->
4. Incompatibility of Bluetooth codecs
Bluetooth transmits audio using codecs, compression algorithms that affect sound quality and stability. If your smartphone and headphones use different codecs or are not optimized for them, you may experience stuttering.
- SBC โ basic codec, works everywhere, but can lag at a weak signal.
- AAC โ Better for Apple, but Android is often unstable.
- AptX is a high quality device, but requires support for both devices.
- LDAC โ maximum quality, but sensitive to interference.
How to check the codec used:
- On Android: Install the Bluetooth Codec Changer app or look at Settings โ Connected devices โ Headphones โ Additionally.
- On iPhone: Codec is always AAC, change.
Decisions:
- ๐ Forced codec installation SBC (The most stable, though not the highest quality).
- ๐ฑ Update your smartphone firmware โ sometimes manufacturers add support for new codecs.
- ๐ง Check if your headphones support aptX Low Latency (if yes, turn it on to minimize lags).
How to enable aptX on Xiaomi
5. Physical damage or wear and tear
If the headphones fall, get wet, or are just in use for a long time, physical defects can cause stuttering.
- ๐ Oxidation of contacts in the charging case or on the headphones themselves.
- ๐๏ธ Bluetooth antenna damage (often after falling).
- ๐ Battery bloating (earphones do not hold charge, quickly discharged).
- ๐ Contamination of speakers (dust, sweat, earwax).
How to diagnose:
- ๐ Inspect your headphones for cracks, dents, or corrosion.
- ๐ง Look, is the sound distorted in one of the headphones (this may indicate damage to the speaker).
- ๐ Check if the battery is swelling (if the headphone case began to "pull overยป).
Decisions:
- ๐งน Clean the contacts with a cotton swab soaked in alcohol.
- ๐ง Replace the battery (in the service or on your own if you have experience).
- ๐ฆ If the antenna is damaged, only replace the headphones (repair will cost more than a new device).
โ ๏ธ Warning: If Xiaomi headphones get wet, don't turn them on right away! Put them in rice or silica gel for 24 hours, then dry with a hair dryer (cold air) for 10 minutes.
6. Software glitches in headphones
Yeah, wireless headphones have firmware, too, and it can work incorrectly.
- ๐ Self-involved reconnection.
- ๐ต Sound distortion (wheezing, crackling).
- ๐ Mike failure when calling.
- ๐ Incorrect charge display (for example, 100% immediately changes to 1%).
How to update firmware:
- Download the official appendix: For Xiaomi/AirDots: Mi Home or Xiaomi Wear for Redmi Buds: Redmi Buds App.
Firmware update
If the update is available, install it (earphones must be charged) >50%).
If the update doesn't help:
- ๐ Reset the headphones to factory settings (usually by pressing the button on the case for 10-15 seconds).
- ๐ฑ Re-flash manually (for experienced users only, look for instructions on the 4PDA).
๐ก
If you've stopped using your headphones after you've updated your firmware, don't panic! Wait 10 minutes, then put them in your case to charge, and 90 percent of the time, they'll recover automatically.
7. Problems with the source of sound (applications, games, calls)
Sometimes stuttering only occurs in specific applications or scenarios, such as:
- ๐ฎ In games (due to high load on the processor).
- ๐ When calling (conflict with VoLTE or VoWiFi).
- ๐ต V Spotify/YouTube (buffering).
- ๐น When watching video (frequency mismatch and audio).
Decisions:
- ๐ฎ In games: Enable Performance Mode in your phone settings or reduce graphics.
- ๐ When calling: Turn off VoLTE in Settings โ SIM-maps and mobile networks โ Network call 4G.
- ๐ต In music apps: clear the cache or reinstall the app.
- ๐น When watching the video: enable hardware acceleration in the player settings.
If the problem is only with YouTube:
- Open YouTube Settings โ Reproduction quality.
- Choose Lower quality (sometimes high resolution video puts a strain on Bluetooth).
- Turn off Autoplay.
