Here's what I understand. Monster Power beats are not what are pictured here. What the image shows are Powerbeats by Dre, the athletic in-ear headphones. Monster Power beats are the over the ear headphones. They are actually much more expensive (close to double the price.) The listing for $62.50 looks like it's from a discount business, so I would be careful. It might be fine, but you might be getting a refurbished set of earphones. Then again, because of the difference between the models, I would make sure you know which one you're getting. Over the ear, or in-ear. Here is a link to the official site so you can compare MSRPs and models. http://www.beatsbydre.com/collection/?cid=PS_google_beats%20by%20dre_Evergreen_Core+Terms_us_na&mkwid=sp6qTczgI|dc_pcrid_46072598937_pkw_beats%20by%20dre_pmt_e&migMedium=paid-search&migSource=google&migContent=s&migCampaign=Brand+Beats+Electronics+-+Exact&migTerm=beats%20by%20dre&matchtype=e
Yes, they do. Not terribly, but they do leak sound when on full blast everyone can hear it. I think it is okay in the gym, because treadmills make a lot of noise as well, but you can't have them on full volume in an office setting.
Right now I have both black and red. If you decide to buy email me again so I can be sure you get the ones you want. Both have a red/black but one has solid black around ear and one has red/black around ear. Thanks.
