First issue with the N-ergy that may be a show stopper. The mic/button is starting to stick and this unit not even 1 week old. I also have lost 1 call when the button press wouldn't work to answer the phone.
Sonically these are blissful but will have to see how this button works out. If it's defective I will try a second unit to see if it's a design flaw.
My V-Modas stuck for a little while. It came undone as I used it. It may be in your best interest to get a replacement through Monster though.
