My brother recommended JBL so I brought this speaker for when I am working in the garden, it clips into pretty much anything and the clip feels robust enough to take some banging around. What really struck me was the sound quality and volume.

First I want to start by saying I'm a fan of JBL speakers. However I am disappointed in this speaker. At full volume I get 4 hours of power. Not great for long periods when there is no power source. I have yet to get it to play anywhere close to 10 hours.

Perfect for what it was bought for. Sounds fine. Good bang for your buck.

My husband likes to listen to music on the golf course but he was sick of using his larger speaker that didn't fit in the cupholders or golf cart compartments. This speaker is perfect because he can clip it to his golf bag and he won't accidentally leave it behind.

This speaker is AWESOME!! I LOVE the colored lights and the strobe, makes the deck look really cool at night. Its loud, the Bass is good. It isnt a HUGE speaker but it is around 35-40lbs, the handles make it easier to carry. I love that I can charge my phone off it as well. Highly recommend.

Loud; Clear sound; good bass

Little heavy

When I first saw the JBL PartyBox 300 Bluetooth speaker, I was very eager to try it. From the first time I saw the pictures, I kept looking at them over and over again. I did see it in my mind as a bit smaller than it is.

How big is JBL's PartyBox 300 Bluetooth speaker? Well, it's smaller than a car, but it's larger than just about any other speaker we've ever reviewed. At $449.95, it's also quite expensive. Beyond pumping out earth-shattering bass, it's a karaoke box, so its name is apt: This speaker is for parties, not so much for Tuesday nights at home with a glass of wine and a book. Is it worth the price and the space its huge frame requires? Only someone in the market for a karaoke speaker that can shake the earth's crust, double as a guitar amp, and put on an LED light show can really answer that question. Ultimately, if you're looking for a mega speaker to power your next party, the PartyBox 300 won't disappoint. Design Measuring 27.1 by 12.2 by 12.6 inches (HWD) and weighing in at a cumbersome 35 pounds, the PartyBox 300 has built-in handles, as well as built-in rubber feet on two side panels and the bottom panel as well, so it can be oriented vertically or horizontally. It's easiest to op...

Only you know whether you need a $450 PA-system-like Bluetooth speaker with karaoke functionality. If so, the JBL PartyBox 300 won't let you down.

Insanely loud with two levels of bass boost; Mic and instrument inputs with gain knobs for karaoke and live music; Solid connectivity for wired or wireless audio
