    • THIS THING ROCKS!!
Style: Speaker + Cargo Sleeve Color: Black
I absolutely love this speaker! I own about 30 bluetooth speakers of all sizes and prices, the sound quality does not disappoint and the bass response is very clean and deep, put it against a wall and the bass really booms. The removable battery is a huge plus because its generally the main reason speakers get tossed out after several years. If the battery takes a crap the speaker is useless but with this you just pull the battery out and pop a new one in. I have not had any battery issues with this yet either. I play this at max volume a LOT and I will truly say that there is absolutely NO distortion. I ran it at probably around 50 or 60 percent volume for about 4 or 5 hours and then had it cranked to max for probably about 2-3 hours after that and it still had about 33 percent battery left when I plugged it back it. If you like having parties and want a truly remarkable party speaker this is a no brainer, especially if you wait for it to go on sale like I did. I have a bumpboxx flare 8 and that speaker gets really loud as well but doesn't have anywhere near the bass that this has. ... show more

    • Great sound
Style: Speaker + Cargo Sleeve Color: Black
Very nice sound quality. Love the bass. Super easy to get going. Batter life is also good but tbh I haven't really pushed it, I usually run it plugged in to mains power. Is rather heavy but that is expected, it makes having the extendable handle nice.

    • Loud and clear
Style: Speaker + Cargo Sleeve Color: Black
The bass has enough thump. I’ve watched multiple videos and reviews on YouTube and was enough to convince me to buy. The clarity is very good and has plenty of volume with just one of these.

    • Quality build and excellent sound!
Style: Speaker + Cargo Sleeve Color: Black
JBL produces a quality product with true RMS rating. Remember a 1000 watt speaker may only produce 100 RMS sound, JBL produces the sound it promises. These speakers have excellent app and sound exceptional. I have JBL 710 partybox and was very disappointed I could not pair it with the 320....but still LOVE JBL! ... show more

    • Fantastic Speakers
Style: Speaker + Cargo Sleeve Color: Black
Great build, sound and light show. I got two of these and they immediately join each other in party mode (same sound and effects simultaneously out of both speakers), and when you download the app they can be easily joined in stereo mode. My phone, computer and mikes all easily join together via Bluetooth. The app let's you set the lights, special (though not that great) party/show sound effects and a 5 channel equalizer in the app but only vol, bass, treble and echo on the speaker. These are heavy so the extending handle and wheels are a blessing. These will run while plugged in or completely on a replaceable battery. These are pretty loud, but if you need a little more noise, use them plugged in as when on battery power the volume us cut back a little. ... show more

Very good build quality, crystal clear sound. I have found that the battery will last a long time unless you turn on the base boost and lights, but it charges quickly
