I purchased this product at a close out sale at a Radio Shack. I was generally pleased with the product, the amplified base provided good audio level regardless of what device or source i was using, however soon as the warranty expired, the base stopped working and plantronics was unwilling to support their product. I still use the headset as headphones. it comes with several replaceable cords with different uses, but I can no longer use as intended, as a headset. I doubt I will be buying plantronics products in the future.
