    This speaker packs a punch. I have the boom 3 so I grabbed the mega boom 3. The boom 3 is one of the best bluetooth speakers I've ever had. This one is good,but I think I still like the boom 3 better.

    I bought this after looking for a Bluetooth speaker. I already own 2 jbl speakers. This one was on sale and after reading about it, I decided to purchase. Great speaker with volume and bass. Great for listening to music or watching movies on a tablet or cellphone.
