Bone conduction headphones for open-ear awareness

The NANK Runner 4 uses bone conduction technology to transmit audio through the skull, leaving the ear canal open to ambient sound. Weighing approximately 26 g, the frame is designed for extended comfort during long training sessions. The grey finish suits everyday athletic use.

IPX8 waterproof rating

An IPX8 rating means the headset withstands submersion, making it suitable for swimming as well as running or cycling. Bluetooth 5.4 provides a stable wireless link to smartphones, tablets or laptops. The open-ear fit stays secure during vigorous movement without inserting anything into the ear.

16 GB internal MP3 player replaces a separate device

Built-in 16 GB storage lets you load music directly onto the headphones for phone-free workouts. Up to 8 hours of continuous playback covers most long-distance sessions. ResoVibe™ technology and OT leakage reduction 3.0 limit sound bleed so nearby people hear less of your audio. Not for listeners who want full noise isolation or in-ear bass response.

Questions about this item

What does Bluetooth 5.4 cap in practice?

It provides a stable wireless link for streaming audio and taking calls from smartphones, tablets or laptops within standard Bluetooth range.

What physical space does the 26 g frame need to sit securely?

The open-ear design rests on the cheekbones just in front of each ear, so no ear-canal or over-ear clearance is required.

How do you pair the headphones for the first time, and what step do people skip?

Hold the multifunction button until the LED flashes red and blue, then select "Runner 4" in the device's Bluetooth menu; skipping the long press leaves the headphones undiscoverable.
