This page serves as a central resource for users seeking documentation for these unbranded or multi-branded audio accessories.

• How do I pair my wireless earphones to my phone?

  Typically, remove both earbuds from the charging case to enter pairing mode automatically. Then, open Bluetooth settings on your mobile device and select the model name (e.g., S800, A21) to connect.

• Ce ar trebui să fac dacă funcționează doar o cască?

  This often requires a reset. Place both earbuds back into the charging case. Depending on the model, press and hold the reset button on the case or the touch sensors on the earbuds for 8-10 seconds until the lights flash. Then, forget the device on your phone and re-pair.

• How do I charge my earphones?

  Place the earbuds into the corresponding slots in the charging case. Ensure the magnetic contacts are clean and aligned. Connect the case to a power source using the provided USB (Type-C or Micro-USB) cable.

• Why are my earphones not charging?

  Check if the charging pins on the earbuds or the case are dirty or oxidized. Clean them gently with a dry cloth or cotton swab. Also, ensure the charging case itself has battery power.

• Are these earphones waterproof?

  Many sports models (like the S800 Runner Pro) are rated IPX8 or similar, making them suitable for sweat and rain. However, standard models are typically only splash-resistant. Refer to your specific model's manual for exact IP ratings.
