Fervit 2-Pack USB-C Female to 2.5 mm 4-Pin Bone Conduction Adapter Square Trapezoidal Contacts

USB-C to 2.5 mm bone-conduction adapter pair

This two-pack provides a USB-C female socket that connects to 4-pin bone-conduction headphones using a 2.5 mm contact pitch. One adapter uses square contacts and the other uses terraced contacts to match different headset sockets. Each unit accepts 5 V input at up to 1.0 A and includes a blue LED that shows charging status in real time. A magnetic coupling holds the connection firmly but releases under sudden pull to protect the headphone.

Check headset pin layout and power needs

Verify that your bone-conduction headset uses a 4-pin connector with a 2.5 mm pitch and confirm whether it requires square or terraced contact geometry. Ensure the host device can supply 5 V at 1.0 A through its USB-C port, as the adapter draws power directly from that source. The magnetic latch is designed for accidental tugs, so confirm the headset cable routing will not exert constant sideways force on the connector.

Suits users with compatible 4-pin bone-conduction

Buyers who own a bone-conduction headset with a 4-pin 2.5 mm interface and want a lighted, magnetic USB-C charging solution will find both contact styles covered in one pack. Users whose headsets use a different pin count, pitch, or contact shape should look elsewhere, as will anyone needing data transfer or audio pass-through beyond simple charging.
