Outstanding - A MUST HAVE.
I mostly write reviews when I am impressed with the quality of the good and yes, I am overly surprised with this small portable speaker. I got it 5 minutes ago and turned it on and the sound is unbelievable. The bass is perfect for me, the sound can be extremely loud with no distortion of any kind. The BT connection is excellent - I carried it in another room and no interference or disruption of any kind, unlike another very famous brand. I tried several brands and at my amazement, this one fulfill my expectations at 500%. It is the ONE I should have purchased in first place. The rubber handle and the shoulder strap are very convenient. The speaker is not too heavy nor too light. I really love it and right out of the box. I just discover that Monster is not only excellent for their various cables but also in speakers! I really highly recommend it and the price is unbeatable! Thank you Monster for providing such quality products.

I Really like this MONSTER Speaker I just bought! It's Not for Everyone......
I Really like this MONSTER Speaker I just bought! First off it is a Very Loud Speaker, which i have been searching for Such a Long time! So Finally found! I like it in every way, Well Built, Sizable, the sound quality is exactly on the Mark for Myself! I am Not a Big Bass Fan! if you are and you purchase this Model, you will be Very Disappointed! This is Not a model that will even get you half way close to your Bass Needs! it just isn't. That is Not to say anything Negative about this Model! I am tone deaf and this is where this Speaker fits in Perfectly for Me! We all like different aspects of sound! MONSTER has blown me away! Great Price Quality Product!

Good but not Great!
The sound quality is great; however, there was no product manual/operations manual included with the product and I have had very little success learning to set the programable radio stations. In addition, I was under the understanding that thed light would go off when fully charged. That did not happen. I am also disappointed that there was no power charger included - I thought it was supposed to be included. Since it is a "c-type" so it was easy to use another charger to charge the device.It is portable. Not too large and not too small. Easy to handle and move about with.Connection to my phone via bluetooth was simple.I cannot speak to the battery life as I have not used it long enough.All in all, the amount paid for the device was good.

Great sound!
Bought this for our church - it packs a punch and holds a charge. Chose this one based on brand reputation and the features. Great value; easy to use - highly recommend.

Portable Bluetooth speaker
I absolutely love this speaker! It's so awesome with its portable size and two handlesThe sound is crystal clear, although you might need to turn up the volume for anything connected via Bluetooth. I really appreciate the option to insert a microSD card filled with music. Plus, unlike most other speakers, this one even has FM radio. The only downside for me is that there isn't much bass - I'm a bass-head, so I need my bass. Nevertheless, it still sounds fantastic, and I enjoy listening to podcasts on it.It's quite large and perfect for backyard use, although it may not be as big or loud as speakers specifically designed for outdoor use. Overall, it's a fantastic value!

At least it's not broken.
Listen, I bought this thing on a whim because it was reduced from $160USD to just $40USD and I was curious about a Monster branded speaker for such a discount.This thing is BAD AT ANY PRICEEven for 40 bucks this speaker has the lowest build quality I've seen in a long time. This is a speaker you'd find at Ross on the impulse aisle with a "deep discount". The sound is loud. That's the extent of the praise. Do not buy this. Check out the Soundcore Motion 300 instead. It competes favorably to Bose whereas this Monster speaker is only one step removed from an actual scam given that, well, at least it's not broken.

Lacks Bass. Poor Sound Quality. Loud.
I got this at a discounted price for Black Friday. $39.99. If that was the full price, it'd be just right. Yep. $40 in sound is about all you get. It's loud, that's for sure. But that's about it. It took awhile to get it connected, but once it does, it will automatically auto-connect when turned on. The silicone handle is nice. It comes with a USB-C cable and a shoulder strap. Monster is not the Monster that once was, unfortunately. Battery life seems on-par with the description, and the unit seems durable. I guess this would be great for jobsites and for the beach. Would be a perfect companion for golf and sports, as well. If you like flat sound with little bass, this is for you. Otherwise, look elsewhere. Ive had smaller generic BT speakers with MUCH better sound. Take it for what it's worth.

Good but not great speaker
The media could not be loaded. I have been using this Monster Bluetooth speaker quite a bit everyday and it works well and keeps a bluetooth connection fine. The sound quality is ok, not a lot of bass and treble is kind of tinny sounding. Overall its a nice speaker but they could have made with better sound quality.
