Query: COMPLETELY WORTHLESS

I went through TWO of these and decided not to give this product any more chances. Both lasted less than one week. The first completely died within five days, while the other started transmitting heavy bass and feedback on the sixth day. The most disappointing aspect of my experience is that I own a desktop computer. This means that my headset lays stationary on my DESK--isolated from environmental impairment--yet the product had still managed to malfunction on its own...on two accounts. This product is far too unreliable to make valuable use out of it.
