HJC Smart systems span different helmet fitments and communication generations. We first identify the exact main-unit and audio-kit marking because similar generations may use different mounts, microphones, contacts and electronics. We test the faulty assembly rather than swap parts blindly.

HJC Smart โ The catalogue lists popular and widely used families. If your exact model is not listed, send the label from the main unit, mount and microphone.
Smart watchesThis Amazfit T-Rex Pro worked only while connected to the charger. Diagnostics showed that the battery was not at fault: the problem was in the motherboard power circuit. Board-level repair restored normal battery operation.
Smart watchesWe replaced the battery in an Amazfit GTR 3. This model must be opened through its strongly bonded AMOLED display, making the repair unusually delicate. The original screen was removed safely, the battery replaced and the watch restored to full working order.
Smart watchesUnder the microscope, this Samsung Galaxy Watch board was covered in severe corrosion. We replaced multiple damaged chips and rebuilt part of the circuitry, but the heart-rate sensor could not be fully restored. An honest look at a difficult water-damage repair.
Exact estimate after free inspection and before work.
We accept the main Bluetooth, Mesh and OEM HJC Smart families listed here and related versions. Send a photo of the exact model label before shipping.
For audio faults, include the full audio kit; for dock charging, include the mount and cable; for pairing faults, tell us the other headset model if known.
Factory water resistance cannot be guaranteed after opening. It depends on the housing, seals, membranes and previous repairs.
