Review: Great wireless mic system but does not come with the XLR Female to 1/4 Inch TS Cable - I'm a retired fitness director and group fitness instructor and am now teaching at several locations so I needed my own blue tooth speaker and wireless mic system. I have used this one for many, many years at the clubs I managed and found it to be superior. The headset is the heavy duty one which you'll need especially if being used by different instructors. I purchased Shure model # BLX14/SM31-J11 wireless headset to connect to my Anker blue tooth speaker. It does not come with the XLR Female to 1/4 Inch TS Cable so be sure to order one ($11.99 on desertcart for the six foot length cable). It comes in four lengths. I called Shure tech. support and they told me I would need to purchase it separately. Just copy and paste in desertcart: Nylon Braided XLR 3 Pin Female to 6.35mm TS Male Unbalanced Interconnect Wire Mic Cord for Dynamic Microphone (Pure Copper Conductors). It's much cheaper on desertcart vs. the Shure website.
