This speaker has been a great purchase. The sound is clear, surprisingly powerful, and more than loud enough for everyday use. I use it daily at work, and the battery life is excellent. I can go a long time without needing to recharge it. Setup was quick and painless. Bluetooth connected to my phone in under a minute, and the connection stays stable even when I move around the room. The call quality is also impressive. People on the other end say my voice comes through clearly. The audio quality really exceeded my expectations. Music sounds rich and balanced, with solid bass and crisp highs. I tried several different music genres, and everything sounded great. Even at lower volume levels, the detail is still noticeable. The speaker itself feels durable and well built. I’ve used it outdoors a few times with no issues, and the handle makes it easy to carry around. I also like the flexible design since it works well standing upright or laid flat. For the price, the quality is hard to beat. I’ve already had several people ask what speaker I’m using. Overall, I’m extremely happy with it and would absolutely buy it again.

I've been lugging this Monster Bluetooth Speaker around for my weekend hikes and beach days, and it's quickly become my go-to for portable audio. At first glance, it's a sleek, rugged cube in eye-catching blue—compact enough to toss in a backpack (about the size of a large water bottle) but built like it could survive a drop from a cliff. The IPX8 waterproof rating is no joke; I accidentally submerged it in a stream during a rainstorm, and it powered through without skipping a beat. Submerging up to 1.5 meters? Check. It's like the speaker equivalent of a tank. Sound-wise, the 60W output delivers punchy, room-filling bass that rattles your chest—perfect for thumping hip-hop or electronic tracks outdoors. Mids and highs are crisp enough for podcasts or acoustic tunes, though it's not an audiophile's dream; the emphasis is on fun, party vibes rather than studio precision. Pairing two units for True Wireless Stereo mode is seamless via Bluetooth 5.4—zero lag, and the connection holds strong up to 100 feet away, even through trees or crowds. The built-in mic shines for hands-free calls; voice comes through clear, and the noise cancellation keeps wind and chatter at bay. Battery life? It claims 20 hours, and I got a solid 18 on high volume during a full day of tailgating—recharges via USB-C in about 3 hours. Controls are intuitive with physical buttons for volume, play/pause, and pairing, plus an LED indicator that's not obnoxiously bright. A couple of nitpicks: It's on the heavier side at around 3 pounds, so not ideal for ultra-light ultralight camping. And while the bass is monstrous (pun intended), it can distort slightly at max volume on complex tracks—dial it back to 80% for perfection. Overall, if you're after a durable, waterproof warrior that turns any outdoor spot into a concert, this Monster speaker roars. Worth every penny for the price—grab it if you hate flimsy portables that die on you mid-jam. Highly recommended for adventurers and party starters alike!

What a speaker!! The sound is very clear and loud enough for my needs. I use it every day at work and the battery lasts a really long time without needing to charge. Connecting my phone was super easy and took less than a minute. The Bluetooth stays connected even when I walk around the room. I can take calls on it too and people say they can hear me perfectly. What surprised me most was how good the music sounds. The bass is strong and the high notes are crisp. I tested it with different types of music and everything sounded great. Even at low volume you can hear all the details clearly. The speaker feels solid and well made. I bring it outside sometimes and it has held up perfectly. The handle makes it simple to carry around. I also like that I can place it standing up or laying down. The price was very fair for the quality you get. My friends always ask me what brand it is when they hear it playing. I am really happy with this purchase and would definitely buy it again.

I spent more time than most searching for a speaker that would go nicely at work to connect and play music while I work. I build robotic automated systems so there is a decent level of background noise— mid-to-low level. These speakers satisfied my needs and mostly met my expectations. I say speakers because I bought two as the pricing was on par with other single speakers of similar quality and wattage from one unit and these were touted as being connected as a pair, doubling my output to 120 watts. Pros: • The sound is rich. I had read a review that said the sound gets brittle at the maximum volume but I did not experience this. The quality stayed consistent and quite pure throughout the full volume range. • Quite convenient for travel — these speakers as a bit bigger than a 99¢ Arnold Palmer can in diameter and about the same height. They carry easily and feel robust and well made. • They were incredibly easy to connect to in regard to my phone and to each—other. A simple button press preformed both functions. • The battery life appears to be quite satisfactory for my expectations; at Maximum volume for 6-8hrs without pre-charging them directly out of the box. I did connect them to a c-port charger before I left for the day and likely will run them off that primarily but the battery life was plenty adequate for my expectations. Cons: On a personal level— the maximum volume never reached a point of “to loud.” I want my music to be loud enough to where I need to turn it down to have a practical conversation. These speakers never really reached that level of volume. The do output sound omnidirectional— but very clearly have a “front” where volume projection is best. This criticism is nit-picky considering that at max volume the speakers never sacrificed sound quality and that actually disguises how my sound they are putting out because of the LACK of distortion. I’ll edit and add to my review after I’ve spent more time with them if pertinent. Bonus: I personally would have been disappointed with just the one speaker but with the two, I have a stereo system that produces quality music at a plenty adequate volume for my entire crew. For the price ~$50/ I’d recommend springing for the two speakers. The options are exponential with where you decide to place the units and I had zero connectivity issues or instances where the sound was out of sync. When I found the perfect spot between the speakers it stopped being a listening experience and felt like a conscious experience which is unique to a stereo set-up and honestly the only way I’d ever like to listen to music. Earbuds can’t recreate the same experience and the closest I have come to a similar experience is a quality set of headphones. I haven’t looked into whether I can add more than just a pair of speakers but I would certainly by another pair just to increase the volume and immersion.

I wanted to buy something for my work to connect to my tab and laptop to use on teams call and also to use for music during free time as i work from home home . To my surprise, it exceeded my expectations with how easy to setup and connect with tab with just single tap on bluetooth button . Also it is waterproof and enough loud sound , infact i have to now lower volume during my calls. Battery left is whole 2-3 days as i used it for my work mostly . Simple to carry around and no way it cheap built . Will be ok to use outdoor also . Really value for money as compare to big brands . Donot need to spend hundreds just for name sake . Really in love with this speaker . Thanks

This speaker is instantly available for Bluetooth connection. I recently purchased it, and it has been working exceptionally well. It is surprisingly loud, and the music sounds clear and crisp. The speaker feels sturdy and durable, suggesting that it will last for a long time. I charged the battery to full capacity and listened to music at about half volume, and it lasted the entire duration of my workday, leaving me with enough battery life to continue listening.

I bought two of the Monster S620 Bluetooth speakers. I put them on my golf cart. They are perfect in every way! I link them together so I can listen to my music in stereo. The base is very surprising for their size! The volume is excellent! I can cruise in my golf cart and don't have any issues at all being able to hear the music! And if I am driving, and don't want to hear the wifey... I just turn them up! 😉 At their price point, they can't be beat!
