    • Amazing Sound!
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 PDT Hello 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 ... show more

    • Versatile and Powerful Portable Speaker
I recently purchased the Monster Rockin’ Roller 270 Indoor/Outdoor Portable Bluetooth Speaker, and I’m quite impressed with its performance. This speaker has a robust design that feels sturdy and durable, making it suitable for both indoor and outdoor use. The sound quality is excellent, with clear highs and deep bass, perfect for any gathering. I appreciate the portability—it's easy to transport, and the built-in handle makes it convenient for taking on the go. The Bluetooth connectivity is seamless, allowing me to pair it with my devices quickly. ... show more

    • Great sound, great battery
I bought to use in my old truck instead of redoing the whole audio system. It sounds great, works great (only used it for bluetooth speaker), long lasting battery and extremely well built. I only had to chage it maybe once a month if not two or more (only drove for about an hour or so a day). Thought it was a little expensive at first but, it's definitely worth it. ... show more

    • Great when paired together

    • Missing knob but good sound
I bought two of these. Great radios. One of the two came with a volume knob which bothers me. It was a return I could tell. Had to take a knob off of something else. Other than that it’s good.

    • Very Disappointed… Battery needs to be replaced after using it twice
We purchased this speaker for my daughter as a Christmas present for her to use during travel softball. Last summer we used the speaker two times and unfortunately she got injured and was out for almost a year. This summer she is back to playing travel softball and we went to use the speaker again we took it out of the closet plugged it in and took it with us the next morning to the softball tournament. When we went to use it the speaker would not come on. We got home we played around with it kept it plugged in for two days and it only works when plugged in. That defeats the purpose of the speaker it is basically brand new and doesn’t work. I have read that we can purchase a battery for it but am not sure I want to waste the money if we will only last us two uses of it. Really disappointed I went with this machine as I was torn between this and the JBL rolling system at the time I felt this one was more durable so that’s why I went with it. Durability doesn’t matter when it doesn’t work. ... show more

    • Awesome
We purchased this Monster to replace a different outdoor radio we had so far it has been great. It’s nice that it you can roll it around to where you want it. It has great sound with local radio stations we can use or Bluetooth. It’s the perfect size and is durable for use by the pool.
