JBL Go 4 - Ultra-Portable, Waterproof and Dustproof Bluetooth Speaker, Big Pro Sound with Punchy bass, 7-Hour Built-in Battery, Made in Part with Recycled Materials (Blue)Recycled Content Certification for Electrical and Electronic Equipment

I’m Floored!!!!! Such big sound for such a small price!!I needed something small, but I wanted a halfway decent sound. I got way more than I bargained for. This little gem packs a whallop. I read some reviewers complaints that there was no adjustment to sound equalization but downloading the easy to use JBL app gave me that option. Clearly, at this price point, I am not going to get perfect sound but the quality that comes out of this little baby is sweet. JBL provides preset options for vocal or energetic or chill or JBL signature settings. Don’t like the settings? Choose their custom option and play around till you get the sound that you want.I tried a little vocal simplicity with a Gino Vannelli solo and hopped over to pure rock with a Prince/Tom Petty tribute to George Harrison. The vocal solo was a little more pure, but the speaker handled energetic rock really well.My husband came in and heard this and immediately asked if I would grab one for him as well. Since I’m going to buy another one for myself, I guess I’ll get one for him, too. Maybe we will sync all three and have ourselves a little concert!

I bought this while it was on sale for $40. There's some muddiness for those picky (usually me), but it's expected for something waterproof, portable size, and price point (wouldn't want to risk a more expensive speaker anyway). Still, it's worth it to have something that's easy to use and safe to have in the bathroom while showering with output that's powerful enough to transfer well. I'll sometimes also just leave my phone upstairs while doing things downstairs and bring the speaker along. There's no drop or delay in the audio, so the range and signal strength are both good.This is too new for me to comment on how long the battery lasts long-term, but it's been good for periodic usage; it's nice that it'll turn itself off after 10 minutes of idle time and charges quickly.Getting it connected takes less than a minute, though the optional app lets you customize the equalizer and see more information about it. I love that I can just turn it on and have the audio transfer over without any fuss. The buttons on top are also easy to distinguish, and the side buttons slightly divot in and will push in, so they're easy to distinguish in the dark too. Very thoughtful functions all around and solid build quality (I've already dropped it once on a hard floor without issue), especially at this price.

I love these little speakers. They punch well above their weight. Between the volume and the bass, they sound about twice as large as they actually are. Battery life is great as well. If you just like to listen to a podcast, the app offers an option for battery saving mode, which will extend the life of your battery even further. These little things seem indestructible. The Bluetooth connection is stable and I feel like I can stay connected pretty much anywhere in the house. I liked it so much that I bought a second one. When you have more than one connected at a time, they sync up extremely well. There doesn’t appear to be any audio lag at all.. you can walk from one room into the other and not even notice a difference in timing. I think this is probably the best small speaker for your money.

Tiny, weighty but in a good way, came with a charge, and super easy to connect and play right outta the box. Downloaded the app and got more information and functionality. Left my phone in two rooms away and took this into an enclosed shower and didn’t lose connection. Great loud sound for such a small thing. I’m in a beige and navy color mood this summer so this matches all my aesthetic for the season. Seems easy to connect multiple together so I want another just so I can play. Definitely recommend

Love the sound quality and volume for such a small speaker 🔊. I bought the clip5 with it to pair the two. I ride an electric scooter as much as possible as a alternative to my car and I can hear my music no problem..even at 45mph. My only gripes are the app isn't very good and getting both to connect with each other takes some patience, should be as easy as they make it out to be. When they're both connected it's like a little surround sound home theater. These little guys pack a good punch!

It's JBL, so you already know it sounds good. Some people complained about it being too quiet, mine is very loud even with a preamp set to -2db. Decent battery, solidly built, feels good to carry around - but it's got a few problems.-The cloth covering wasn't completely glued down in one spot. I was able to sort of push it back into the shell, and it seems okay for now, but I might have to superglue it down later.- The notification sounds don't scale with volume, and they're bizarrely loud. The 'power down' sound is particularly annoying and always scares my cat.- Bass makes it vibrate pretty badly with the volume up, to the point where it physically slides across flat surfaces when standing upright. If you don't prop it against something, it could easily fall off a table.- As with all JBL products, the charging cable is very short (only 1ft) so you will need another USBC cable in most cases.All in all I'm still willing to give it 4 stars since it does sound good for the price, but I hope they make some improvements if they make a GO5.

I have been using a JBL Flip 5 and love it, it fit perfectly in a water bottle cage, but left me with one less bottle. Plus it's heavy, and weight is a concern while bicycle touring. This JBL Go-4 is perfect for my needs. Loud enough for personal listening while riding, compact, lightweight, and I was able to customize the installation using industrial strength Velcro and one Velcro strap. Very satisfied with this purchase. A win win in every category.
