International power cord for wireless earbuds

This international power cord is designed to charge the wireless earbuds with model number 71006940. It connects to a USB power source to replenish the charging case that stores and powers the earbuds. The cord suits users who need a replacement or spare cable for travel or home use. It supports the charging function for the semi-open dynamic earbuds with 10 mm drivers.

USB charging limited by port power

The cord uses a USB connector to draw power from a computer port or wall adapter. Charging speed depends entirely on the output of the USB source you connect it to. The cable itself does not regulate current or voltage beyond the standard USB specification. It cannot charge the earbuds without a powered USB port or compatible adapter.

Check USB port availability and type

Before ordering, verify you have a free USB-A port or a suitable adapter for your power source. The earbuds require a charging case that connects via this cord, so ensure the case is functional. Confirm the cord’s connector matches your power supply, as no alternative plug types are included. The product does not support memory card charging or wired audio pass-through.

Questions about this item

What does the 10 mm driver size mean for sound?

The 10 mm dynamic driver produces the full 8–25000 Hz frequency range at 120 dB sensitivity, giving clear highs and adequate bass for music and calls.

What does Bluetooth 5.0 actually deliver in daily use?

Bluetooth 5.0 provides a fast, stable link with automatic pairing, supporting SBC codec for wireless audio and microphone use with phones or gaming devices.

How does the USB charging connector limit recharge speed?

The case charges over a standard USB cable; no fast-charge protocol is specified, so recharge time depends on the USB power source you use.
