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)

Solid speaker, loud, clear, small.Background: I have owned a lot of computer speakers and speakers of all sizes and I work as in audio. I'm not a complete expert, but I do have a ton of experience in all things sound. For a speaker that can fit in your pocket, this thing is really good. I bought it for a vacation, so we could play music in our cabin, and it delivered well beyond my expectations. It was plenty loud, with more room to go. There is a major difference from listening to things straight from a laptop, tablet, or phone with little effort and it sounds pretty close to a real speaker setup.Battery: The battery lasted just around 8 hours of nearly continuous play. A nice feature: it shuts down after awhile if it does not detect a signal from your device. Great for saving battery and not forgetting to turn it off.Build Quality: Very durable, it seems. It has a rubber shell. I would say you could drop this off a roof and it would survive. A nice option for camping, vacations, bonfires, rugged activities where it may take some abuse, but also where a power supply doesn't come easy and you need portability. The blue color with grey and orange accents is really nice.Sound Quality: I found the sound to be clear, with plenty of volume. There are speakers that project nicely, without being "loud" - I would not put this into that category, but those speakers cost at least 4x the price. There were times where it seemed to be getting too loud for everyone. But, for the price, that is nothing to complain about. There is a lot of bass, but not a crazy amount (which a lot of brands think more bass means good). It has a pretty even EQ; you can hear everything well. Since it is portable, just move it around the room and find the best spot where it can be heard, but won't be in everyone's face, isn't bouncing off reflections like hard surfaces, and it will sound awesome.Value: Well worth the money. I will be using this a lot, i can already tell. JBL is a very experienced brand in this department. I have heard other bluetooth speakers. Although I haven't A/B compared anything else, this one sounds just as good as anything else out there I can remember, including the more expensive JBL tube.

You guys... if you are looking for a compact speaker if you are on the go, hiking, backpacking and such, this will not disappoint. I've used the JBL Go 3 for a few years already on backpacking trips, and have been more than pleased with the performance of this one. This Go 4 has upped the sound quality, battery life, and even a few grams less in weight over the Go 3!! So, if you are on the fence of just owning one, or upgrading from a previous version, this is a solid choice!! Great at home also, for chores outdoors, or in the house, or even singing in the shower, it's just worth it to have if your phone speakers are not enough! You will not be sad that you own one.

This speaker really has all the essentials and surpasses and expectations I had for it. I'm honestly pleasantly surprised. It packs enough bass and functionality for the price while not breaking the bank. I haven't seen how durable it is yet but I have yet to learn. So far it pairs well, sounds great, is very useful and is very versatile! It is very easy to set up and I enjoyed the quality of the material used
