The situation where only one of a pair of Xiaomi or Redmi wireless headphones suddenly starts working is familiar to many users, whether you use the popular AirDots, the sports Earbuds Basic or the more advanced Buds 3 series models. Often the problem catches you off guard: you take out your gadgets from the case, but the sound is heard in only one ear, and the second is silent or not visible in the Bluetooth list.
In most cases, it's early to panic, because it doesn't mean that the speakers are broken, and most often, the left and right modules are out of sync, so they stop transmitting sound to each other and they work as two independent devices, and software failure or one of the batteries is the main culprit behind this anomaly, and you can fix it yourself.
In this article, we will discuss the mechanics of work in detail. TWS-We'll give you headphones and a step-by-step algorithm to restore their collaboration, and you'll learn how to reset your settings correctly, check the charging contacts, and reconnect the headset to your smartphone to enjoy stereo sound again.
The main reasons for the dissynchronization of headphones
Before we start to actively reanimate the gadget, we need to understand the nature of the failure. Xiaomi wireless headphones are complex electronics where the left and right channels must constantly communicate. If this communication is interrupted, the sound disappears in one of the ears.
The second common cause is the simple discharge of the battery: in some models, the case can charge the headphones unevenly due to oxidation of contacts or dust, as a result, one module is battery-operated, and the second, when discharged, simply does not turn on, creating the illusion of breakage.
⚠️ Warning: If the headphones were left unused for a long time, the lithium-ion battery could have gone into a deep discharge. Put them in a case and leave them on charge at least for a few hours. 30-40 minutes, even if the indicator does not immediately light up.
It is also worth considering the influence of third-party factors, such as electromagnetic interference or crowded Bluetooth memory in a smartphone. If the phone is stored devices, the system may not correctly allocate resources when connecting the headset.
