Wireless headphones have become an integral part of everyday life: they are convenient for sports, work and leisure. But even with such simple devices, Android users sometimes encounter difficulties, ranging from connection issues to intermittent sound. This article will help you figure out how to properly connect Bluetooth headset to a smartphone, adjust the sound and troubleshoot typical problems.

We will look at not only the basic connection steps, but also the nuances of working with different versions Android (from Android 10 to Android 14), features of codecs (SBC, AAC, aptX), and we will also give recommendations on choosing a headset for specific tasks - be it listening to music, games or calls. If you have already tried to connect headphones, but the sound comes through the phone speaker or is constantly cut out, here you will find solutions.

1. Preparing your smartphone and headset for connection

Before connecting for the first time, make sure that both devices are ready for pairing. Let's start with the smartphone:

  • 📱 Update Android: Go to Settings → System → Software Update and install the latest patches. This will fix possible bugs with Bluetooth.
  • 🔋 Charging the headset: Make sure the headphones are charged at least 30%. A low-power device may not be detected.
  • 🎧 Pairing mode: Activate it on the headset (usually hold down the power button for 5-10 seconds until the indicator blinks). In AirPods, Sony WH-1000XM5 or JBL Live 660NC this process may differ - read the instructions.
  • 📴 Disconnect other devices: If other devices (smart watches, speakers) are already connected to the phone (smart watches, speakers), temporarily disconnect them to avoid conflicts. Bluetooth-devices (smart watches, speakers), temporarily disable them to avoid conflicts.

Important: some headsets (for example, Bose QuietComfort Ultra) support multipoint connection - simultaneous work with two devices. If you do not need this function, disable it in the headphone settings through the proprietary application (for example, Bose Music or Sony Headphones Connect).

⚠️ Attention: On Android 12 and newer there is a bug due to which some headsets (especially with the codec LDAC) can only connect after rebooting the phone. If the device is not found, restart your smartphone.
