A featherweight speaker with a heavyweight sound

Comments about JBL Go4 Ultra Portable, Waterproof & Dustproof Speaker
I've never a heard a sound so big and full-bodied coming out of a speaker so small. This pocket rocket is built to take a lot of abuse and keep on rocking. You can swim with it, drop it, kick it, leave it in the sun, rain or snow all day and it still sounds as good as new. The JBL Go4 will never let you down. For less than a full tank of gas you get buy two Go4's and double your pleasure or share one with a special friend!
Great from office to beach speaker

This is a great small portable speaker. I use this speaker to replace the lousy speaker on my work computer and take it to the beach. Highly recommended

Comments about JBL Go4 Ultra Portable, Waterproof & Dustproof Speaker
Compatible with other gen4 or better JBL speakers for connecting more than one speaker via Bluetooth. Great sound as always from JBL "Harmon Kardon".... Every type of speaker from them sounds great. This one clips onto anything. I use the gen 3 at work outside every day. I purchased this one for at home use, in the yard, garage ,etc.. #sweepstakes

I refer to it as my mini-speaker. It easily fits in my purse and the sound quality is excellent for listening to music or audiobooks. I highly recommend this product.

I love my JBL speaker. It's easy to just pick up and go, it looks great, it's rugged, and it sounds really good with a good clear sound. It's just as loud as a bigger speaker but it is more portable. The battery lasts for hours too. Well worth getting.
Sound like very good speakers in a car radio
