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 Amazon 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 Amazon: 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 Amazon vs. the Shure website.

Excelente.
Resiste muy bien. Soporta la humedad y da buena calidad para cantar eventos en vivo. Para mi gusto le faltó estar 1 centimetro o 2. Mas largo. Ya que me queda un poco de lado. Pero funciona perfecto
