    • 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

    • Exceptional sound quality in a compact design
I couldn’t be more impressed with this indoor speaker! The sound is crystal clear with deep bass and balanced mids and highs—it easily fills the room without any distortion, even at higher volumes. The sleek, modern design fits perfectly with my home decor, and it’s lightweight enough to move from room to room. Setup was a breeze, and the Bluetooth connection is rock solid with no drops. I’ve used it for everything from casual background music to movie nights and it performs flawlessly every time. For the price, the quality is outstanding. Highly recommend for anyone looking for a reliable and powerful indoor speaker! ... show more

    • Perfect for picnics and beach trips. Sound quality is amazing!
Lightweight. The suitcase roller style rolls smoothly. Very loud! Perfect for our outdoor adventures. I have not yet tested how long battery life lasts. The wireless charger is large, and is down in a small cubby like area to keep it from sliding around. The light son the front have 3 brightness levels. The sound clarity is impeccable. Clear and sharp. Very user friendly. We didn't need to use the instruction manual and the microphone that comes with it is also loud and clear of static. ... show more

    • Good quality speaker
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. ... show more

    • DO NO BUY
Less than great don’t waist your money on this one here. I purchased this last July with minimal use and not keeping the battery plugged in. Now I needed to use this and the battery was dead. Charged it 24 hours and all I can get the battery to charge to is 20%. I noticed on the monster app mentioned if your having battery issues to connect with them. I reached out to find Out I am out of warranty but for $70 I can get a new battery replacement. For a radio that should last 30 hours and the price of this radio it should be more dependable.
