I bought the Monster Rockin Roller 4 and the Ion Explorer on the same day. I couldn't decide at the store so I decided to compare at home. The Monster is my pick for two reasons. 1- The sound is crisp clean loud and amazing. FAR superior to the Ion. 2- Monster has bass/treble adjustments for music and gain/echo adjustments for microphone and guitar. Very important in my opinion. The Ion is has a much higher quality build, bigger/better wheels, and the waterproof port covers are much better. It also looks cool and has a light show bar for a dance or party purpose. The Ion downside is the sound. Compared with the Monster, the Ion sounds muddy, almost like its in the next room or under water. The Ion is plenty loud, just not clear and crisp. There are no bass/treble adjustments or gain/echo adjustments. What you hear is what you get and adjustments must be made from the input device. If you want something handsome, durable, with party light bar, and water tight, get the ION. If sound quality is your priority, get the Monster RR4. I had a hard time finding comparison reviews for these, so I wrote one. Hope this helps.

I am writing this to inform all unhappy customers who bought this and suffer the ALERT every 10-15 minutes of use. There is a fix that silences the alert, unfortunately there is one caveat... you have to do this every time you power on the box. Here Goes.....Power up, Go to NOAH by pressing Source button... Press the volume button in to select on or off for each channel of NOAH. Select OFF and press right/ left arrow to go through each channel (There are 7 of them). . This will disable alert problem. Then you can go through the channels to figure out which channel is your area and turn that area on. The issue is the system automatically turns on all alert zones when powered up. So whenever there is Alert anywhere in NOAH's system it alerts you as well. I do this every time I use the system and never have an Alert.. Happy Listening!

I had to drive to a Sam's 30 miles away from home to find this but as soon as I saw the RR4 I picked it up. I have been very happy with it so far. I like the updated design changes Monster made for the new model. You have the ability to change the color of the built in lights,(7 or 8 to pick from vs. just 1 color on the RR3) a built-in bottle opener(cheers) and hardware to stack multiple RR4's. Both the RR3 and RR4 claim 100 watts total output but my 4 is definitely louder than my 3. They both have the same mic, battery life and TWS feature for linking them wirelessly. You will lose one of the AC pass thru ports on the RR4 as there is only 1 instead of 2, but that was not a deal breaker for me. I plan on getting a second one before summer arrives along with 3 more ez-play speakers to complete my setup.

First I bought the Ion Outback 2 from Sam's. This was a mistake as the Outback 2 audio is very muddy sounding, way too much Bass and little Treble. Sooo, I took the Outback back to Sam's and got a refund. Then I bought the Monster RR4. This one is a keeper. The RR4 audio is wonderful, clear and you can easily adjust the audio to YOUR preference with the equalizer preset buttons and Bass/Treble control. Really, there is NO comparison. The RR4 sounds much much better. For those that are worried about the NOAA radio alert going off constantly, you can email Monster Audio support and get a firmware update emailed to you. It is very easy to do, all you need is a USB thumb drive to do the update. This eliminates the annoying NOAA alert. Besides the better audio, here are somethings the Outback 2 does NOT have and the RR4 DOES have: 1. Superior FM/AM reception, also better NOAA reception. This may be because the RR4 has an exterior antenna. 2. iPhone App 3. Lithium battery 4. Preset Equalizer buttons AND Treble/Bass adjustment control. Very very happy with the RR4 and the free RR4 APP for the iphone and adds more value and easy of control.

Just picked one of these up at my local sams club. Solid speaker sounds great. However there are a couple annoying things to get used to. one is that when you turn it off and then turn it back on later the volume is way louder then I had it when I turned it off, it doesn’t remember the speaker volume. The other is the NOAA weather feature has an annoying alarm function that you have to remember to turn off manually every time you turn on the unit. The alarm alerts you that there is some kind of weather alert in your area. Three times now I forget to turn it off and this annoying bull horn sounding alarm will go off when I’m listening to music. The speaker should remember the settings you have when you turn it off instead of having to turn off the alarm and turn down the volume every time. Also the sams club listing says it’s waterproof but I can’t find anything on the box or in the manual that says it’s IPx rated waterproof. Overall it’s a great sounding speaker.

Bought Monster RR4 on March 1st, Battery only lasts 2 hours on Bluetooth, not 100 hours as advertised. Does not play nearly as loud on Bluetooth as radio does. I called customer service, and was sent a form to repair, they want me to send a check for $25 and pay for shipping, may get it back in 4 weeks. I have an Ion Explorer bluetooth speaker, it is a much better product than Monster.

This is my first time purchasing this brand and i loved it. Battery is amazing i don't have to be charging it every day.

I bought this speaker to take to swimming party and drive in movie I needed a speaker with am fm radio I love it

Love it ! Wish I would of ordered a second one while they were on sale to give 1 to my twin grand kids for there Birthday !!

I purchased this item about a month ago, it works great, the sound is very good, and the price was right.
