Boytond 520-2-1640 Bluetooth Headset with Dual-Device Connection and Mute Button

Where it shines

When you need to take calls while moving between work tasks or spending time on the road, the Boytond 520-2-1640 keeps communication close at hand in a single-ear design. Bluetooth 6.1 wireless connectivity and dual-device connection make it practical for managing calls across two connected devices, while the physical controls let you handle key functions directly on the headset.

Its noise-canceling microphone with wind-noise reduction is designed to help your voice come through in busy surroundings. A dedicated mute button is useful for quickly pausing your mic during a private moment or meeting.

The essentials

This in-ear headset pairs a flexible ear hook with a swiveling microphone boom, so you can adjust its position for either ear. S, M, and L ear tips offer a choice of fit, and the single-ear format leaves the other ear uncovered. For long stretches of calls, the charging case is described as providing 10–12 hours of talk time per charge and roughly 100 hours total. Its digital battery gauge makes the remaining charge easy to check, and USB-C charging replenishes the case.

Choose the ear tip that feels secure, then adjust the hook and microphone boom to position the headset comfortably. The physical buttons handle calls and volume, while the mute button offers a direct way to pause microphone pickup. To check remaining charge, read the digital gauge on the case, use its USB-C connection when it needs charging.
