Hi, yep I busted my Sennheiser PC 151's, seems I’m in the mood for breaking things what with my Zen’s suicide last week. 
Unless anyone can give me a reason to choose the 161's instead; might purchase another set of 151's as they served me well for 2 years and still would be if i hadn't damaged them. After close inpection it appears only things that set them apart is the 161 having open speaker system + the manufacturer claimed Frequency Response 15.....23000Hz, versus 18.....22000Hz of the 151. I suspect it's just marketing bull to justify price diff along with the claimed 161's having "Unique 3D, 360 degree surround sound". 
Anyone care to share an opinion.
