LENOVO USB/ALOG HDSET BY SENNHEISER The Lenovo USB/Analog Headset by Sennheiser is designed to enhance your multimedia experience. Whether it is used for Internet voice conversations, music or voice applications, this headset, designed jointly with Lenovo, offers excellent audio quality in a comfortable form factor. It is lightweight and convenient for use both in the office and in mobile environments. Connect via USB or Analog. The headset can be connected to any notebook, desktop, CD/DVD or audio player via either a USB or analog connector. This flexibility is useful when a system's existing USB or analog ports are already connected to other devices such as a keyboard, mouse, memory key or external speakers. The USB adapter has its own audio amplifier that converts analog signals to digital. When using Internet chat or voice applications, the adjustable, bendable and pivot-able noise-canceling microphone ensures your voice has clarity on the receiving end by reducing ambient background noises.
