Single-Ear Bluetooth 6.1 Headset

The Xoruezls 520-2 is a mono in-ear headset built for professionals who need one ear free while staying connected. It pairs with two devices at once so calls on a phone and media on a laptop never clash. A single multifunction button handles answer, reject, redial and playback without reaching for a screen.

10-Hour Battery with 500 mAh Case

The earpiece runs for 10 hours on a single charge and the included case holds 500 mAh for multiple top-ups. Bluetooth 6.1 operates in the 2.4 GHz band (2.4000–2.4835 GHz) for a stable link beyond 10 metres. CVC 8.0 noise cancellation suppresses background sound so the far end hears only your voice.

14.2 mm Driver for Extended Calls

A 14.2 mm dynamic driver with composite diaphragm produces a 48 dB signal-to-noise ratio at 13 ohms impedance and 48 dB sensitivity. Latency sits at 40 ms for tight audio-visual sync during video conferences. The single-ear design keeps situational awareness high, making it unsuitable for buyers who want immersive stereo isolation or dual-ear coverage.

Questions about this item

How do I pair the Xoruezls 520-2 headset with two devices at once, and what step do people often miss?

Pair the first device via Bluetooth 6.1, then turn the headset off and back on to enter pairing mode again for the second device; the step many miss is re-entering pairing mode after the first connection.

Which part will need replacement first — the earpiece battery or the 500 mAh charging case?

The earpiece battery runs for 10 hours per charge and cycles more often, so it typically degrades before the larger 500 mAh case battery.

At what point does the 2.4 GHz Bluetooth link become unstable during a long call?

The effective range is over 10 metres; moving beyond that distance or placing thick walls between the headset and phone is the first limit you hit.
