A4Tech FH200U USB Stereo Headset, Noise Cancelling Microphone, 50mm Speaker Drivers, USB Plug-and-Play Connectivity, Comfortable Over-Ear Design

Product Overview The A4Tech FH200U is a wired USB stereo headset designed for conference calls, online courses, Skype communication, webinar presentations and everyday multimedia. It combines 50mm speaker drivers, DSP-based digital audio processing, a unidirectional noise-cancelling microphone and a full-size over-ear wearing style. A4Tech offers the FH200U in Blue and Grey color variants. The core specifications remain the same across these versions, so the main difference is the exterior finish. 50mm Stereo Drivers with DSP Audio The FH200U uses 50mm speaker units with a specified frequency response of 20Hz to 20kHz. A4Tech lists 16-ohm impedance and 100dB sensitivity. A built-in DSP, or Digital Signal Processing, stereo chipset processes the USB audio signal and is designed to reduce unwanted background noise while maintaining clear voice and multimedia playback. For buyers, this means the FH200U relies on digital USB audio rather than the analog output of a 3.5mm headphone ja
