I was contacted a year or more ago and asked to provide bassheads to test and help in the development of a set of headphones that would provide quality sound and tactile response. We need to do that via amp and eq as it stands right now. Skullcandy tried to do this the easy way and it turned out the way going the easy way things do. It would seem on my brief listen via Note 4 and Mojo that Taction Technologies has hit the mark. More thoughts to come. Target date for mass release is March as of now. I have 2 days with these so I will be video taking and listening a lot. The case is insane.
