JBLGo 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 (Squad)Recycled Content Certification for Electrical and Electronic Equipment

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.

I have had some other small JBL Bluetooth speakers before and was excited to buy this one after reading many very positive reviews.I concur with these reviews. The build quality and sound quality are excellent. It’s a small speaker that defies its size, sounding much better than its size or price would suggest.I take it with me when travelling and keep it in a small bag complete with various charging cables and power adapters. It’s UBS C charged like so many devices today which means less cable varieties to lack.Great for traveling given its size and sound quality.

So far so good! This little thing does pack a loud punch, and worked for hours right out of the box! I’m trying to run the battery down before I charge it for the first time, but even after a couple days of casual listening it’s still going. I guess that should speak for itself ☺️ Sound is great and can get pretty loud without distorting. This is easy to use and comes with a quick setup guide.

This is a great little speaker! I travel a lot and I love to listen to music in my motel room! Works perfect for that application! Biggest drawback is that you can’t EQ the sound of it! It has a pretty smooth low end but I wish I could add a little top end to hear the top end of a high hat or S’es on the vocals! For the price point it’s good enough for my application.

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.

Saw this JBL Go4 for $39 and was tired of listening to my Music on my phone through the 1/4” slot at the bottom of phone, so I read the great reviews and got this. It sounds crazy good, and my wife said, “why didn’t you get this before now”. I had no good answer, but love it and will use it working around the yard, and when cleaning the cars. Such a great value.
