Truefree HD-100 Wireless Neckband Earbuds

These in-ear headphones combine a flexible neckband with Bluetooth 6.0 connectivity for cable-free listening. The 11 mm dual-magnetic drivers deliver a 5 Hz to 20 kHz frequency response and 32 ohm impedance. An IP67 rating protects the unit against sweat, rain and dust during indoor or outdoor activities.

Built for sport and daily commutes

The secure fit and lightweight design suit runners, cyclists and gym sessions where the earbuds must stay in place. Commuters benefit from the 20-hour battery life and a 10-minute USB-C charge that adds roughly five hours of playback. Buyers who prefer fully independent true-wireless buds or need over-ear comfort for long studio sessions should consider other form factors.

20-hour battery with 10-minute fast charge

A single charge provides up to 20 hours of continuous playtime for music, podcasts or calls. When the battery runs low, a brief 10-minute USB-C top-up restores enough power for about five more hours, keeping downtime minimal between workouts or journeys.

Questions about this item

How do I confirm the headphones are paired and delivering sound after first setup?

After pairing via Bluetooth 6.0, play audio and verify both earpieces produce sound; the 11 mm dual-magnetic drivers should deliver crisp highs and deep bass, and the LED indicator will show a steady connection state.

What accessories are included and what must I supply myself?

The box contains the Truefree HD-100 earbuds, eartips, a USB-C charging cable and a user manual; you will need a USB-C power source such as a wall adapter or computer port to charge the neckband.

Which version should I choose if I want the longest playtime between charges?

The HD-100 model provides 20 hours of operating time on a full charge, and a 10-minute fast charge adds roughly 5 hours of playback, making it the highest-capacity option in this series.
