Monster Rockin' Roller X Indoor/Outdoor Portable Bluetooth Speaker | Powerful 1000W, 15” Subwoofer | All Terrain Wheels, Weather Resistant, Dual Mic & Guitar Inputs, TWS Pairing, App Control

It's an absolute beast. It is MUCH bigger than I expected. The subwoofer on it is gigantic. The thing weighs 74 POUNDS. If you want to activate the bass boost, hold down the button on the front that has a red marking for 3 seconds. My neighbor can hear it. Not exaggerating. I asked her if I was being too loud, and she said she couldn't hear it. I chuckled, went home, and blasted it. She texted me moments later and said, "It is shaking my kitchen."The audio quality is pretty good. It's not on the level of Sennheiser, but is close to JBL. I have a high regard for the JBL charge 5, so any comparison is a positive.The battery life is absurd. I forgot to plug it back in and listened on low-medium volume for about 16 hours. It was down to around 80% battery.Be careful using an audio booster or mixer with this speaker. It has a built in mixer. The built in mixer stacks with an external one, so if you double up on bass, I bet you could damage the speaker. If you do want to use an external mixer on your laptop etc, make sure you have the speaker set to "flat" in the audio settings.

I was very leary on buying this being so new. But I chanced it based on the reviews of the old models. This thing is 72 pounds and heavy but has off road wheels that roll over gravel nicely. And it rocks extremely well. Even as 1 in my 20 x 40 shop rattling the walls and being heard all the way down the streetIrbwas so good I bought a second to pair under tws mode them together. Even buying 2 of them it's still cheaper than a 710 and has the effects of a jbl ultimate. And a wired mic is included and can do karaoke while you play music

Pretty good speaker but not better than the lower price ones by the same maker no louder just a heavier box The speakers are in

The reception on the radio setting is not that great!

Works great

The media could not be loaded. Is very bad product handle is not good sound is not enough for the name “ monster “ 👎👎I do not recommend

Bass boost is awesome and the speaker is pretty simple to use. It definitely puts out plenty of volume. We use it for our daughters travel basketball and travel softball seasons. Awesome indoors and out! Would definitely recommend!

This was used as a PA system for an outdoor event. Easy to use, loud enough so everyone could hear the speeches. Just hit the off button when done and roll it away.
