Monster Rockin’ Roller 270 Indoor/Outdoor Portable Bluetooth Speaker | up to 200W of 270 Degree Sound & up to 100 Hours of Playtime

love this thing! I purchased this to use for my dance team for practice at competitions and when we have practice outside. The battery life is awesome, and the sound quality is stacked! if you were on the fence about buying this, I would suggest you buy it! the wheels on it roll so smoothly that it is easy to maneuver across different types of terrain! the microphone is also really loud and clear! The bluetooth connectivity is also easy as well and the charging function works really well also.

I've only had this for about 2 hours so far, so I can't speak to it's longevity/durability. I've noticed several reviews complaining about failing batteries and failure to charge so I'll definitely update my review with fewer stars if I experience the same problems. The sound quality is excellent. Deep, booming bass and high trebles without distortion. Some people might complain about the weight. Yes, it's heavy but that's a plus. That means it has large speaker magnets for optimal sound and a large lithium cell. That's why it ships with wheels and two handles. It's about the same size as a wheeled overnight travel bag. I haven't used the included microphone so I can't speak for its quality but it's heavy and the build quality is good. It doesn't appear that they chose this microphone as an afterthought just to fill out the box.Pros:The published bluetooth range of ~9 meters is accurate. I was able to actually go about 12 meters before the connection started breaking up.Includes an FM radio which is great if you don't have a device loaded with music. Favorite channels can be stored.Has several equalizer pre-sets.The wireless quick charger works well and the speaker chimes when you place a device on the charging pad to let you know that charging has commenced. This was a great idea because most phone batteries will run flat before the battery inside the speaker which would cause a premature end to anyone's party.Audio quality is excellent. It's so good in fact that I'm considering buying another unit for stereo output if Monster's TWS system supports stereo.It's wireless, so no need to run speaker/power wires that are needed with conventional wired speakers.It's portable so I can easily move it around my pool and take it on the go as well. It's a much better option than installing indoor/outdoor speakers mounted permanently outside in the weather. Perfect for picnics, the beach, outdoor movie nights, or backyard/tailgate parties.The bass output is already very good so most people won't need to use the Bass Boost function unless they just want to shake the walls.Cons:This unit is NOT a stereo speaker. It combines both left and right channels into one audio output. I'm assuming that if you want true stereo, you need to purchase another identical unit and pair them together using Monster's TWS (True Wireless System) but I'm waiting for monster's tech support to confirm this or not.USB port is for charging only. An option to play music from a USB stick or hard drive would be nice.The audio quality of the FM radio is very flat, so be prepared to boost the bass and treble to the max to get the audio even close to sounding normal, and even then it still sounds a bit off.EDIT: Monster got back to me the next day after my enquiry about stereo capability when using their TWS feature. According their tech support, adding a second unit and connecting them via TWS does in fact create a stereo speaker system. Their response is below:James Smith (Audio Support)Sep 24, 2024, 07:22 PDTHello Stephen,Thank you for contacting Monster Audio support.Yes if you purchase another same model speaker you can use the the TWS option where the output would be in true 2-channel stereo.For future interactions, please refer to this case #xxxxxx.Thank you for choosing Monster Audio and have a great day.Regards,James Smith

Awesome radio. Very durable. Charge your phone on it. Super loud. Great handle easy to maneuver.

Keep in mind I just hooked this up... but the sound is pretty bad as*. I'll adjust my review of I find any flaws, but so far I'm happy.

We purchased a Rockin Roller 270, it was great for month until it started having battery life issues...at first it would last the whole weekend then wouldn't last 1hr on a full charge. So we bought another one, it was ok for a few months. Then it started having battery issues, then the on-off toggle switch stopped working so you couldn't turn it OFF. Then other issues with connectivity, charging and battery life followed. We chalked the 1st one up to a fluke, but then the 2nd one was crap too. We loved the speaker when it worked, even gave them a 2nd chance, but unfortunately these things are riddled with issues so it's not worth it.Also, Monster will not help in any way if the speaker is more than 1yr old.

I really enjoy the speaker for in home/garage and outside in the garden. The music carries just far enough away that it will not bug my neighbors.The radio function doesn’t work very well. The stations I usually listen to are heavy with static. I don’t know why.It comes with a plug in microphone and it is crisp and easy to use for sure. The cord is long enough that your not hovering over the speaker while your talking into it.What I actually purchased it for was to use as a PA system for my 35th high reunion that I was hosting. I was going to use the microphone to gather people for pictures and make announcements during the event. What I came to realize was the speaker in a crowd did not carry very far. I think it definitely has something to do with the watts of the speaker. I think an 800-1200 watt PA system would have had the sound carry better in this crowded and noisy area. The only real downside of this speaker is this piece.The Bluetooth connects fast, and the pull handle makes it easy for transporting.

I am extremely happy with this purchase! It is easy to set up and use and it sounds great. I like how it confirms your connections with either a light and/or audible tone or voice comment, I like it's considerable volume (wattage/loudness), the bass and the treble quality, I also like the wireless charging of your phone, and that it even comes with a microphone for karaoke! It has an extendable handle and wheels like a piece of luggage and seems very well made. The only improvement I would ask for is that its Bluetooth range would work over a longer distance. It works about 30 feet away, but we have a very large backyard and 30 feet doesn't go very far. Thankfully it is quite loud and can be heard for a long distance. In any case, I love it and am considering buying a second one which would automatically pair with the first one and then give me another 30 feet of range for a total of approximately 60 feet.

The best speaker I've bought to date! We take this camping and we use to blare walk up songs at softball games. It's sturdy, but heavy. Has charging capabilities that I haven't used too much unless in times of necessity. If just using to play music, holds a charge for quite some time!
