This was a darn good idea from the minds of geeks. I have a set of Beats Studio headphones that I thought were useless because I have the iPhone 7+and would have either charge, or power access due to the lack of a headphone jack. I went almost 2 years not knowing that there was a wireless option and was not about to pay ANOTHER $300 for my beats! Luckily I was browsing for a smaller headset and this was in the wrong place at the right time. To my delight, Its specifically made for Beats Studio! I would have given it 5* but... if your very active like myself, you would find it annoying having to readjust the Bluetooth often to keep from falling out. Especially if you are a runner. My suggestion is use a THIN piece of double sided gorilla tape. Too BIG, and you will not be able to get it off possibly breaking the Bluetooth. The product is well worth the money considering you will not have to buy another set of headphones.
