At least they were under $40. The base is very heavy and it is very sturdy. all i can say is that after learning how to choose a mouse which is not the looks but if it fits your palm then this mouse is literally the best for me feels like it was made specifically for me really comfortable and it looks nice too all thought i didnt like how it was delivered. I fell asleep with them in one night and had no problems the next day. #No sibilance#Detailed Bass (not punchy or enchaned at all. Really like the all black. No problems with pairing or charging. Upon opening I found that a corner chipped off my case so thank goodness it came in a plastic bag. Great product works great with my daughters system. These headphones are close to those at a fraction of the cost.
