Monster Bluetooth Speaker, Superstar S310 Portable Bluetooth Speakers. 20W True Wireless Stereo Pairing Deliver Dynamic Sound,Waterproof Speaker,…

This is great portable speaker 🔊. Not too small and not too big. Perfect for my need. I use this speaker for my laptop since my laptop has crappy speakers. This are great for watching movies and listening music. This are not 360* speaker sound only comes from one side but it’s very loud. It advertises built-in 4000mAh powerful lithium ion battery guarantees up to 20 hours of continuous use!

Some of the key features are:

Pure Monster Sound: offers a natural, authentic sound and powerful bass.

Latest Bluetooth 5.0 Technology: own fast and stable transmission without tangling within 10m.

IPX5 Water Resistance(not water proof): splashproof and weather-proof protect your bluetooth speakers against rain and water.

Built-In Microphone: For clear, hands-free calls.

Support Wireless/TWS/TF Card Mode.

I bought two of the S310s for the stereo connectivity, which as it turns out is a real pain to setup. They’re light weight compared to a JBL Flip4, but the sound isnt there. Theyre quiet by comparison and have almost no bass. They crackle at high volume too, which sucks.

Worse than that;

The charge times are stupid. I mean, they take longer to charge than they do to drain. From 60% battery it took almost 11 hours to get to 90%
They have yet to reach 100% charge. I dont have patience to wait 20 hours for the damn thing to reach 100%.

Next; Their control is laggy. Theres a huge delay between the speaker and your phone, and vice versa. Approximately 2 to 5 seconds delay.

The sound On/Off chime is LOUD but the speaker isnt loud in Bluetooth mode, weird right?

It gets worse…

Tried downloading the Monster App off Google Play…

Dont… Just…

Dont. -Rage quit.

Overall? Buy the JBL Flip 4. its more expensive, but its clear why. This speaker is mediocre at best. I think I’ll be sending this pair back and just buy another Flip 4, then using Samsung Media Pairing have the same feature as the Stereo mode in the Flip 4 without the hassle of cheap components, and crappy hardware.

Flip 4 is five stars all across the board.
Monster 310, 2.5 stars at best…

I had not really thought about Monster as anything but a legendary maker of premium cables and connectivity hardware. But I picked up the S310 because I wanted something really portable for the back yard this summer. In fact, the convenient wristband caught my attention. Often I’m going downstairs with items for the grill or beverages and don’t have a free hand for a Bluetooth speaker. So the carrying strap was a really useful feature. But I am getting ahead of myself.

I’m very pleased with this little speaker. Here are the highlights:
1) It paired with my phone immediately.
2) It connects very quickly.
3) The sound quality is much better than I would expect with such a small speaker system. It fills my back yard with clear and full sound. It stays clean near to the very top of its volume range. There is indeed bass, even in such a small driver. Well, actually, there are 2 drivers and a passive radiator. Certainly it is not earth shaking bass. That is just not physically possible from such a compact unit, but the build quality is sufficient to deliver low end to the soundstage. The documentation states that Monster’s audio legend, Noel Lee, personally designed and tuned this little guy. It’s well-balanced and clean sound gives me no reason to doubt this claim.
4) Battery life is impressive so far. After giving it a complete charge, I’ve been using it for at least 12 hours (of music, not standby) without a recharge at a decent volume.
5) Speakerphone mode is actually pretty good. I have another, more expensive Bluetooth speaker with a speakerphone mode and my callers complain that I sound like I’m in a closet. I did not have that experience with the S310. People could hear me and I was not the least bit embarrassed to use it.
5) Water resistance is something I have yet to really test. I’m just too chicken to let a nice piece of electronics get wet. It does have a rubber seal to protect the power port and SD slot.
6) Oh yeah, the SD card slot. This is not a feature I would use but I could certainly see how it might come in handy. For example, you could load up a card of kids music and let them enjoy it without having to use your phone or give them a tablet. Also, if, heaven forbid, you find yourself without WiFi or a cellular signal, you can still enjoy dozens of hours of music.
7) I don’t have 2 of these, but if I did, you can pair them so that they will work as left and right channels and double your power. I may take advantage of that.
8) The only feature missing, and maybe I’m old fashioned, is a an 3.5 mm aux input. I hardly ever use one of those old things, but I find the a comfort nonetheless. Ah well.

While this is about the size of less expensive Bluetooth speakers, you really get what you pay for with the Monster S310. It is a small but loyal audio companion.

 Battery life is ridiculously good, more than I’d ever need at one time, so no running out of juice while out and about with it.
Which is what you’ll be doing if you purchase this, as it’s a larger speaker but is exceptionally loud for its size. It’s about the size of a can of Arizona tea, as the attached picture shows.
Crisp highs and boomy bass make a great speaker for blaring EDM at parties or enjoying a pop album. The mids are recessed, muddy, and unexceptional, but I do not complain about this.
It’s waterproof alright, and while I haven’t fully submerged it, running under a faucet and using it in the shower has done nothing to it. It has very thick rubber gaskets that inspire confidence in the IPX rating.
This is the speaker you’ ll carry with you to pool and dance parties.
It’s unbearably loud at even half volume, a comfortable solo experience is found at 15-20%.
It’s become very apparent this is not geared for home and office listening, it’s a loud, powerful on-the-go speaker and is a college freshman’s dream.
Audiophiles can look elsewhere, this speaker doesn’t meet the requirements for any level of critical listening.
It’s loud, boomy, shiny, and serves it’s purpose surprisingly well.
I had sound quality issues with the first unit I recieved, reaching out for support was painless, and I recieved a new working unit very promptly.
If you need a thumping can to toss in your car for the occasional party, it’s not at all a bad pick.

For what it is it sounds pretty darn good, it has a decent amount of base if you position it in just the right spot in your room but if you don’t get it in the right spot it just has no bass at all but anybody who is familiar with speaker placement knows how that goes. But overall I’m pretty satisfied and I am crazy picky about sound, I’ve been in the high-end audio since I was a kid and this is definitely not high-end audio, I love the fact that in the description that says this is just like being right in front of the live artists on the stage but it’s not even close, that statement right there almost makes me want to get it one star LOL, it’s a shame companies print descriptions like that to make a sale but

if you’re just looking for a nice sounding Bluetooth speaker that won’t break the bank, something that’s kind of a medium size so it’s still nice and portable but not teeny tiny for casual listening I would assume you’ll probably be happy with it.

I like it, it’s not perfect and it doesn’t sound as good as they claim it does butts I’ve heard things that sound way worse than this,. Now if I listen to this for a while and then I turn on my home stereo this speaker makes me appreciate what my home stereo sounds like,. But this is probably one of the better sounding little Bluetooth speakers that I’ve heard for casual music listening, It is very impressive for what it is.
