Query: Bad Design = Discomfort/Pain and Problems

Due to a poor design this headset causes discomfort, and eventually pain, when worn.Not to mention I've been recently experiencing problems with the left left speaker, which cuts off when the cord is jolted (to get it working again one must 'fiddle' with the cord around the "controller" then, once working again, handle gently).In conclusion, the bad design of this product causes not only problems, but discomfort and pain as well. My advice: spend a little bit more to ensure you get a better quality product.I am personally disappointed because I usually have a good experience with Logitech products.
