These are authentic, purchased directly from Monster. Comes with all originally included accessories, original box, and Miles Davis - Kind of Blue cd(still sealed).

The rubberized outside of the hard case has become tacky over time, so you likely won't want to use it. Luckily, Monster included 3 cases with these for some reason. One of them was the suede? case I carried them in, it has gotten scuffed up a bit. The little bag that they included for the ear tips I believe is still in the wrapper.

The only other defect is the strain relief of the left side iem has split. These things sound awesome, very bass heavy but still detailed, and originally retailed for $499. Asking $150 plus shipping. I can take more photos if you're interested as well, just ask. These are also listed on ebay for more.

Will also include a pair of Ultimate Ears 700 with them at no extra charge. I replaced the plug on them, you can see a picture of the soldering on the plug.

Will also include a free pair of Master & Dynamic MW07 as well. The battery life on them isn't good but they sound great IMO. I think I still have the box and other tips but need to find it first. No extra charge for these either.
