Monster S310 Upgraded Bluetooth Speaker, Portable Bluetooth Speaker, 30W True Wireless Stereo Pairing Deliver Dynamic Sound, IPX6 Waterproof, 24H, for Family Outdoor Pink

Love it. Sounds better than my JBL Flip and if the battery holds out for 24hr playback as advertised, (which my phone won’t hold out for!) then it’s GOLDEN! I’m already 5 hours in to an overnight charge and it’s still going strong. Had an issue connecting first time, but after forgetting the device on my iPhone and giving it a full charge, it worked perfectly this morning! Connected it to my windows laptop after turning off Bluetooth to “break” the connection from the iPhone and it worked flawlessly! Can’t wait to get to a beach to use it! Hopefully I won’t have to test the waterproof factor, always weary as to not tempt fate and only use that for emergencies!

Why did you pick this product vs others?:The Monster S310 Bluetooth speaker absolutely exceeded my expectations! From the moment I turned it on, the Pure Monster Sound, no distortion, just powerful and dynamic audio.I love the True Wireless Stereo pairing — can pair two together for true stereo sound.Connectivity range is incredible — I can walk around the house or even head outside without losing signal.Battery life is another huge win.Highly recommend this speaker for anyone who values great sound, reliability, and portability.

This speaker truly exceeded my expectations. The sound is rich, clear, and surprisingly powerful for its size. The bass is deep without being overwhelming, and the highs are crisp. Bluetooth pairing is fast and stable, and the battery lasts a full day with moderate use. It’s lightweight, making it perfect for travel, and the build quality feels premium. Whether I’m using it indoors or outdoors, the performance stays consistently great. Highly recommended for anyone looking for a reliable and affordable speaker!

After reading all of the reviews about this speakers sound quality and finding myself in need of a more portable speaker than my HK Onyx 6 and this being 75% off bringing the price from $159 to $40 I grabbed it up.As soon as it arrived I unboxed it and paired it to my phone. Pairing was very easy and hassle free. I'm impressed with the volume of this speaker, and the highs and mids are a 7/10 but I put bass at a 4/10.I might be spoiled because I've got two full sized active subwoofers at home and a 12" JBL in the car, but to me this sounded very underwhelming. If it's bass you're after, go with a JBL Charge or Extreme, because this just didn't blow my hair back the way I hoped it would. I'm actually consider returning it and going the JBL route, but for $40 I'll probably hang onto it.The lanyard is a nice touch and the button layout and design is nice but this one isn't for bassheads.

I got this speaker to play white noise for sleep. I didn’t want one that emitted bright lights but also had a long battery life. This one fit the bill. It has a faint blue indicator light that doesn’t illuminate in a dark room and it lasts the whole night. However, if I listen to music prior to using for sleep, sometimes the battery dies a little before I have to get up. Most of the time, the battery is adequate however, but wish it lasted a little longer.

I’ve tested quite a few portable Bluetooth speakers, and this one punches above its weight. The 30W output delivers deep bass and clear highs — perfect for both music and podcasts. The True Wireless Stereo feature is a game-changer; pairing two units for real stereo sound really fills a room. Battery life holds up well on medium volume, and the build feels solid and travel-ready. Highly recommend for indoor and outdoor use!

Works well and light enough to take a long for beach trips or to the pickleball courts. Sound is loud and clear enough but nothing ground breaking for it's slim size.

It says waterproof, but I took mine to the river and it got a little water on. It never worked again. I used it one time.
