So I had purchased my Monster Turbine Golds and paid roughly $300 after tax from best buy. After a week or so I was determined to get my hands on the Copper Pros as I hear they are more balanced and produce more detail. Well yesterday I just notice that all the ControlTalk versions seemed to have dropped their prices on amazon quite a bit: Copper at $244 and Golds at $198. The versions with no ControlTalk are still the same prices as they were before. I'm just wondering if there is a reason for this price drop? Is there something wrong with the ControlTalk version? Is there a difference in sound quality versus the non ControlTalk?
