Hey so I bought these as a gift when they were on sale for someone; that person already had them so I never ended up gifting it (fail!)
I have the receipt and stuff for it, and the headphones have a lifetime warranty with Monster. It is sealed in the box, never been opened. I have a pair for myself and they are great. They come with about 10 different sizes of ear tips so you can find the right one for your ear size, and they come with clips to make a hook on your ear if you aren't an earbud person. They sound great and retail for $399 plus tax on monster canada's website and all the retail electronic stores around here.
I will sell them for $200 (I got them on sale). Comes with receipt from Futureshop.
