    Bought this item for my daughter for a Christmas gift. She absolutely loves it, especially the feature that lets her and her friends connect multiple speakers located in different places for a better overall sound.

    Partying up is sometimes tricky and all the megabooms aren’t readily recognized. I have 2 Megaboom 3s and one Boom 3 and the Boom is seen on the app more easily than the second Mboom even though it’s further away. Mboom is definitely fuller sounding than the Boom. N

  • Comes out of the box with Hip Hop EQ

    I just about returned the Megaboom 3 as it has too much bass and muddy mid range the way it comes out of the box. Even using the EQ options in Apple Music couldn't even start to lower the bass and lower mid range into audiophile territory. Then I installed that the "Boom" app on my phone that give you a 5 band equalizer and some other nice features. If you leave the center EQ slider where it is and stair step up the upper mid and treble slider and stair step down the mid base and lower base sliders the speaker starts to sound pretty good. Another big plus is you can turn it on from your phone app and the blue bluetooth range is up to 150 feet. A lot of value for $150. I am keeping it.

    I got it on sale for Christmas. Best buy for whatever reason had this one on sale for cheaper than the others because of the color. But it's easily a speaker that can compete with the $200-$300 ones.
