Three-pack USB-C in-ear headphones

This set contains three wired in-ear headphones with USB Type-C connectors. Each unit uses a 10 millimetre dynamic driver rated at 32 ohms impedance and 98 decibels sensitivity. The cable measures 120 centimetres and includes an in-line microphone with touch controls for calls and playback. The pack is aimed at users who want spare sets for multiple devices or shared use.

USB-C digital audio interface limits

The headphones draw power and signal directly from the host USB-C port, so audio quality depends on the device’s internal DAC and amplifier. Maximum input power is listed at 5 milliwatts with rated power of 3 milliwatts, and total harmonic distortion reaches 3 percent at 1 kilohertz. Frequency response spans 20 to 20000 hertz. Devices without USB audio class support or with limited output current may not drive the drivers to full volume.

32 ohm impedance decides compatibility

The 32 ohm impedance determines how loudly the headphones play from a given USB-C source. Phones, tablets and laptops that supply sufficient current at this load will deliver the rated 98 decibel sensitivity; those with weaker headphone amplifiers will sound quieter. Buyers who need higher volume from low-power ports or who prefer wireless freedom should look elsewhere.

Questions about this item

What is the difference between the three earbuds in the pack?

The pack contains three identical USB-C earbuds, each with a 10 mm driver, 32 ohm impedance and a 120 cm cable. The only variation is the colour option so you can pick a different shade for each device or share with family.

How does the 98 dB sensitivity translate to everyday listening volume?

At 98 dB sensitivity the earbuds reach loud volume from a typical phone or laptop USB-C port without needing an external amplifier, so music and calls sound clear at comfortable levels.

What does the USB-C connection actually support on these earbuds?

The USB-C plug delivers digital audio and power for the built-in microphone and in-line touch controls, enabling call handling, volume adjustment and track skipping on any compatible USB-C device listed.
