Sarevile Bluetooth Headset with USB Dongle, Single-Ear

The Sarevile Bluetooth Headset with USB dongle is a single-ear wireless headset engineered for clear calls, long battery life, and a comfortable fit for office users and truck drivers.

This lightweight headset combines Environmental Noise Cancellation, a flexible boom microphone with mute, and a USB dongle for reliable computer connectivity. It supports Bluetooth V5.2 for mobile devices but also includes a plug-and-play USB receiver to ensure a stable link with desktops and laptops that lack built-in Bluetooth. The single-ear, open-ear design lets you monitor your surroundings while staying connected.

How clear will my calls be in noisy environments?

The headset uses advanced ENC (Environmental Noise Cancellation) to reduce background sounds so the person on the other end hears your voice more clearly. This makes it suitable for open-plan offices, delivery vehicles, and other loud settings where ambient noise can interfere with conversations.

• Dedicated ENC processing to suppress road and office noise
• 270° rotatable boom mic for precise mic placement
• One-touch mute to block the mic instantly

How long will the battery last during a shift?

Equipped with a 400mAh battery, the headset delivers extended runtime to cover full workdays and beyond without frequent recharging. With measured talk time of up to 50 hours and long standby capacity, it’s built for users who need dependable all-day performance.

• Up to 50 hours of talk time for multiple shifts
• Approximately 200 hours standby when not in active use
• Fast recharge cycles to get back to work quickly

Will it stay comfortable during long calls or long drives?

The design emphasizes low weight and adjustable fit, with a memory foam ear cushion that conforms to the ear for less fatigue. The open-ear single earpiece permits situational awareness, which is important for drivers and on-site staff who must hear surroundings while talking.

• Ultra-lightweight construction reduces pressure on the head
• Adjustable headband for personalized fit
• Soft memory foam earpad for extended comfort

How does the USB dongle work with my computer?

The included USB dongle provides a plug-and-play solution for computers without Bluetooth. Insert the dongle and set the system audio to the device labeled “M99+” to route calls through the headset; remove the dongle to reconnect via standard Bluetooth pairing with phones and tablets.

• Plug-and-play USB receiver for fast pairing with PCs
• Simple audio selection step: choose “M99+” as input/output
• Bluetooth V5.2 compatibility when dongle is unplugged

Who is this for? The Sarevile Bluetooth Headset is aimed at professionals who need reliable voice communication and situational awareness—call center agents, remote office workers, delivery drivers, and truckers. It’s also a practical choice for any computer-based worker who wants a hassle-free USB audio option alongside mobile Bluetooth connectivity, combining long battery life, noise suppression, and a comfortable single-ear design for extended use.
