Lenovo 300 USB-C In-Ear Headphones

The Lenovo 300 are wired in-ear headphones with a USB-C connector and an in-line microphone. They include three sizes of silicone ear tips and a media control button for playback. The 9 mm dynamic drivers deliver digital audio with a frequency response up to 20000 Hz. Weighing 0.051 pounds, they are built for portable use with compatible USB-C devices.

Suited for mobile professionals needing simple

These headphones work with devices that provide a USB-C digital audio interface. They are not for users who require active noise cancellation or wireless freedom. They are not for listeners who prefer over-ear comfort or a detachable cable design. The single in-ear coupling may not suit everyone.

USB-C digital connector with 9 mm drivers

The USB-C plug carries both power and audio, removing the need for a separate analogue jack or battery. The 9 mm driver units produce a frequency response of 20000 Hz at 32 ohms impedance. This combination decides whether the headset matches your device and sound expectations.

Questions about this item

Do the 9 mm drivers need any extra power to reach full volume from a phone USB-C port?

No, the 32 ohm impedance and USB-C digital connection draw all required power directly from the host device.

Does the in-line microphone pick up fan or keyboard noise during long calls?

The ~3 k ohm microphone impedance focuses on close-range voice and rejects most background sound.

Will these work on a laptop that only has USB-A ports?

They require a native USB-C port; a passive USB-A to USB-C adapter will not provide the digital audio signal they need.
