    • Good speaker for a great deal.
Note: I got it during an excellent deal & there was a massive discount. So far, so good. Great sound, superlative battery life, & just overall a quality speaker. It touts itself as an excellent waterproof outdoors speaker but I can't speak to that. I don't know if I would be able to splurge for the full price, but it is definitely a solid mid-price Bluetooth speaker. No problems with connectivity & a full sound. It's small enough to fit in the average cargo shorts pocket, as far as that goes. Arrived quickly & in excellent shape, & I would definitely purchase from them again. ... show more

    • Great sounding speaker from MONSTER
If you are familiar with my reviews you know I have a lot of bluetooth speakers and headphones 😆 I have another one.. the price on this speaker I couldn't pass up and plus I have a lot of MONSTER speakers anyway.. when I got this I was surprised how small it was because I didn't think it would be this small 😦 but the sound is incredible.. it pairs real easy and it sounds great! I believe MONSTER is phasing out this series of speakers I do recommend it if you want a small portable speaker it's really easy ... show more

    • sounds great if you don't need bass
I caught it on a deal for $30 so all my comments have to be taken with a grain of salt. Except for the lack of bass, these sound great. Crisp, clear, even turned all the way up there is very little distortion. It's small but the sound is big. Even the light show is kind of cool. Light weight and easy charging. That being said, it claimed to have deep bass but it doesn't. Very disappointed as that was the whole point of the purchase. ... show more

    • Great speaker great price
Sounds good especially at this price. The flashing lights are a little annoying you have to turn them off eash time you turn it on. Plenty of bass. I use it with streaming from my phone and it's very easy to pair.
