Saw this on macrumors and found this interesting, i guess this issue would affect the beats market if apple stops selling them.
Several Monster headphone models using Apple's Remote and Mic technology do not meet Apple's technical specifications. These headphones use conductive flanges, which can result in electrical shorts that cause an iPod or iPhone to pause and play erratically. Customers may not be aware that the issue is caused by the headphones and may believe that the iPod or iPhone is defective instead. There are no known safety concerns and no known risk of damage to the iPod/iPhone or headphones.
