    Nicest little speaker ever!!! All I need.
    This speaker is amazing!!! It is just as good as my large JBL. I truly don’t understand why someone would invest in the big one (I’m not the most knowledgeable when it comes to gadgets but I know this speaker works JUST as well as my JBL flip 6). The quality is so great. The battery lasts a long time, hours and hours on end. It comes charged and ready to use right out of the package. It’s easy to use and I have no issues whatsoever with connecting my phone to it. It connected super easily right away when I first opened it and I’ve never had to reconnect again. It is 100% worth every dollar. I take it on walks outside with me and I use it in my bedroom everyday. I love the camo version, it looks sooo nice in person. The bottom has some rubber strips so that it doesn’t slide around or fall off of slanted surfaces for example. It’s grippy. The speaker is also waterproof!!! Big plus. So happy with my order. Get it!!!

      5.0 out of 5 stars A Good Personal Speaker
      Reviewed in the United States on March 10, 2026
      Color: RedVerified Purchase
      It’s not going to underpin a party, but this is a good personal speaker. Bluetooth connects fast and reliably. The battery lasts for ages. It turns itself off when not in use. The sound is orders of magnitude better than an iPad Pro for near field listening. Two or three people will be able to watch a movie comfortably on an iPad. It’s as if it turns your phone into a radio - that is to say, it’s loud enough that you can put your phone and the speaker down whilst you work in your room, say cooking or doing the laundry. You don’t have to keep your phone right next to you anymore. It’s also showerproof so yay if you like to sing in the shower. At sub $40, it seems like good value to me.

      Love JBL products. This is a replacement JBL Go. We recently left one behind on a family trip clipped to a rental umbrella on the beach in Puerto Rico (don’t do that!). I would buy it again and again. This little guy packs a punch. It’s kept us jamming on many trips. Great battery life and clear sound. Won’t break the bank, waterproof and durable. Easy to connect to bluetooth. Lightweight and travels well. Love all the colors offered. I may purchase another one soon as a backup or gift so I do not need to keep sharing mine. Highly recommend this portable speaker.

      Excellent quality sound in a small highly portable package. Easy to use - Bluetooth connectivity happens quickly with one button. So far the battery life has been great - I’ve used it for as long as 5 consecutive hours without losing power. Seems well constructed and appears to be a good buy .

      The pink is so cute! This little speaker seriously impressed me. The sound quality is amazing for such a compact size, it’s clear, surprisingly full, and gets plenty loud for both indoor and outdoor use.

      I love how portable it is. It’s easy to toss in a bag or take on the go, and it being waterproof makes it perfect for pool days or being outside without worrying about it getting damaged.

      The battery life has been great so far, and it connects quickly without any hassle.

      Overall, an awesome speaker for the size and price. I would definitely recommend it if you want something small but powerful.

      5.0 out of 5 stars Good sound for a tiny speaker, easy to use
      Reviewed in the United States on March 16, 2026
      Color: PurpleVerified Purchase
      The purple color is bright; not easily overlooked when packing up from a picnic or traveling. The sound is great for casual listening. This isn't a full-scale, annoy-the-neighbors volume but certainly loud enough for a small group or a single room. Easy pairing. The hardest part was figuring out how to open the box! There is a black unlabeled pull tab to be removed unless you tear the whole box apart. Comes with its own charging cable. I haven't tested the battery life but am unlikely to be using it for more than 3 hrs at a time. The size is perfect, about the same as 2 decks of cards (stacked). The construction appears to be durable. The rounded edges make it a little unsteady on uneven surfaces. The loop handle is strong enough to use a carabiner to attach to another bag.

      I picked this up because I wanted something small and easy to throw in a bag, and it does a lot right for its size. Sound quality is actually pretty good, and the bass is better than I expected from something this small. It works well for listening around the house, in the garage, or outside when you’re close to it.
      Battery life has been solid, and I like not having to worry about it getting splashed or dusty. It feels well made and easy to use, and pairing was quick.
      The only real downside for me is the volume. It just doesn’t get loud enough for bigger spaces or when there’s a lot of background noise. For a small room or personal use it’s fine, but it struggles if you’re trying to fill an area or use it with a group.
      Still a good little speaker, just keep expectations realistic when it comes to volume. That’s why I’m giving it 4 stars instead of 5.

It works well for listening around the house, in the garage, or outside when you’re close to it.
      Battery life has been solid, and I like not having to worry about it getting splashed or dusty. It feels well made and easy to use, and pairing was quick.
      The only real downside for me is the volume. It just doesn’t get loud enough for bigger spaces or when there’s a lot of background noise. For a small room or personal use it’s fine, but it struggles if you’re trying to fill an area or use it with a group.
      Still a good little speaker, just keep expectations realistic when it comes to volume. That’s why I’m giving it 4 stars instead of 5.

      Amazing little speaker. For the price, this is about the best thing you’re going to get. Music quality is good and it is very loud for how small it is. Perfect for travel and waterproof too, recommend 🥳

      Great little speaker for travel and around the house. Sound is good for the size of the speaker. Looks very well made, battery life as advertised, associated app easy to use.

      5.0 out of 5 stars Awesome Little Speaker — Big Sound in a Small Package!

      I’m really impressed with the JBL Go 4! For such a compact speaker, the sound quality is amazing — clear, balanced, and louder than I expected. It’s perfect for taking with me everywhere: bike rides, beach days, backyard hangs, and even in the shower thanks to the water-resistant design. The Bluetooth connection is quick and stays strong, and the battery lasts long enough to get through most of my day without needing a charge. It’s super easy to use right out of the box, and the build feels sturdy and well-made. If you want a portable speaker with great sound, solid battery life, and rugged design without spending a lot, the JBL Go 4 is a winner. Highly recommend!
