Designed to make every conversation count, the VT9603 BT helps you stay focused and professional in noisy environments—from open offices to home workspaces and on-the-go meetings.
Professional-sounding calls in noise
A built-in Environmental Noise Cancelling (ENC) microphone and wideband/HD audio reduce distracting sounds (talking, traffic, pets) so customers and colleagues hear you clearly.
Dual device flexibility
Bluetooth 5.0 multipoint lets you stay connected to two devices at once (e.g., laptop + mobile). Switch between calls and music without missing anything.
All-day comfort
A lightweight design with soft, breathable leatherette ear cushions and an adjustable headband keeps you comfortable through long shifts and back-to-back meetings.
Power that lasts
Get up to 21 hours of talk time and up to 500 hours standby. Charge via Micro-USB cable or the desktop base; the base includes a second port to charge your mobile phone.
Simple controls
Answer/end, mute, and volume adjustments are on-headset. Manage computer calls easily, and handle smartphone calls via the multifunction button.
