usb-a headset feature and Advantage
AS28 USB-A headsets for call center Features:
- Wideband Voice. The frequency range is 50Hz-10kHz, perfectly preserving sound details and reducing hearing fatigue. Clear and lifelike call quality creates a professional and reliable impression.
- ENC Noise Cancellation. The USB-A/USB-C port and U30 inline remote control enable ENC noise cancellation. When the noise is more than 50cm away from the headset, the other party can clearly hear your voice, even over nearby voices, music, air conditioning, keyboard sounds, and other noises. These noises are virtually inaudible, ensuring professionalism and privacy.
- Comfortable Wearing. Weighing only 110g, the headband is made of 304 stainless steel, lightweight and bend-resistant. The earcups feature 60mm protein-like earmuffs for comfort and breathability. The boom arm rotates 330 degrees for quick calls, and the microphone is bendable for adjusting the angle for calls.
- U30 in-line control. Integrated volume up/down, answer/end, and mute functions. Measuring 2.2cm x 6.5cm, the device features a non-slip silicone material for easy operation.
- Unidirectional microphone. It only records the voice directly in front of the microphone, effectively blocking noise from the sides and back. This is crucial for operators.
