The Xtream™ H4 Stereo Headset with Microphone are designed to prevent interruption in an open environment such as a call center conference room customer/tech support station and clerk’s desk. The dual 3.5mm connectors work directly with your computer through the microphone and headphone input ports. The built-in omnidirectional microphone picks up sound reliably.  The flexible shaft allows you to adjust the microphone’s position for optimal performance.
