Fun and portable!
The JBL Go 4 is the perfect little portable speaker! It’s incredibly compact and lightweight—fits easily in a pocket or clipped to a bag—yet it delivers surprisingly big, clear JBL Pro Sound with punchy bass for its size. Whether I’m at the beach, hiking, or just hanging out in the backyard, it fills the space nicely without distortion at reasonable volumes.The IP67 waterproof and dustproof rating gives me confidence to use it anywhere, and the battery lasts a solid 7 hours (plus extra with Playtime Boost). Bluetooth pairing is fast and reliable, and the build quality feels durable and premium

Best Bluetooth Speaker I Have Had, Maybe EVER!
Holy cow, absolutely perfect!Love the color, great price for what it is, easy to charge, etc etc etc. Hold a charge a LONG time, use it every day and have for about 6 weeks, and still have only have to charge it fully once. Works great in the shower for my music or audiobooks, no issues getting soaking wet. Connected easily, and stays connected.Lightweight, versatile, easy to use built-in clip to snap onto my backpack to carry wherever I go.AWESOME.

Big sound... tiny speaker
Edit - this morning, this speaker fell off a shelf about 5 feet above the ground, due to the vibration... vibrated right off!! It took the lick and kept on playing!! The rubbery outer layer protects this little box with huge sound!I am so impressed with this little speaker! The JBL Go 4 may be compact, but it absolutely packs the sound. The audio is crisp, loud, and fills the room much better than I expected from something this size. It connected to my phone in seconds, and the battery life has been excellent...it holds a charge for a long time. First day... 5 hours at the pool. I plugged it i

This waterproof speaker packs a punch!
Not only is the sound quality great it gets loud enough for outdoor/indoor use! I love the portability and design options as it is available in a range of colors.I was able to connect it very easy to mine and my friends phone depending on who was controlling the music.I have noticed a lot of products are changing to USB-C charging port which is nice as I have lots of those plug in's at home and this portable speaker was no different and has a USB-C charging port. So far I have been able to use this speaker anywhere from 6 to 7 hours on one charge and haven't had any issues with charging or bei

A Sound Choice… get it? lol
I use this speaker often. While I cook, clean, shower, and when my kids and I go out in the yard for fresh air. Connected easily with my iPhone. Doesn’t shake the windows but loud enough. I think it was a good price. I like the purple color. Battery lasts pretty long. I can go a few days of frequent use without charging but probably couldn’t last all day. Came with a guide for the buttons but it’s simple. Small enough to throw in my purse for when we go to the beach.

JBL GO 4 are good small speakers
I have had a pair of the JBL Go 4 for going on 2 years.Function: I got these for times when I need lightweight, small Bluetooth speakers while traveling. Like my other quality Bluetooth speakers, the JBL Go 4 connects reliably via Bluetooth.Sound Quality: The speakers' sound quality is good but limited by their size. As one should expect, there really isn't much punch to the bass no matter the setting. There's only so much bass enhancement software can provide.Noise: No humming or buzzing.Software: Initially, the JBL Portable App reliably paired the two speakers in Stereo. HOWEVER, the latest

Big sound in a small box
Rugged and great-sounding speaker that just works. Simple to configure and control for big sound anywhere. It's also a good-looking little unit with a lot of color choices to fit most tastes. USB-C connection makes charging simple, and the battery really does last as advertised. The controls are easy to access as well, with large clearly-visible buttons. The ease of pairing for stereo is a big plus, and I'm planning to get a second unit for that purpose.
