  • 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

  • Great purchase
Style: Speaker + Cargo Sleeve Color: Black
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

  • No Battery life
Style: Speaker + Cargo Sleeve Color: Black
Battery duration is grossly exaggerated! First use on the beach after letting battery get a fully charged and it died after 6 hours, I have an older unit (300) that Ive had for 3 years and the battery last that long.

  • Replaced outdoor PA system with this one speaker.
Style: Speaker + Cargo Sleeve Color: White
Great speaker. I wish the pairing with a 2nd one would also work with the wireless mic. But just 1 is amazing, everyone loves it.

  • 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
