Great speaker! You'll love it!
Style: Partybox Encore Essential
We bought this to use out by our pool this summer and we have LOVED it!! The quality of sound is great. It's super easy to connect to blue tooth. We have even used it with a microphone (Hello pool side bingo!). It's easy to carry out and in with a big handle on top. A charge lasts a long time, at least a day by the pool - we plug it in at night when we come in. Love this, would definitely recommend! ... show more

Outperformed the 310 party box! Amazing for the size
Style: Partybox Encore Essential

The sound quality of the speaker is absolutely amazing. The base is enough to vibrate things in the room, and you can even feel it if you’re laying on a bed. I had a party box 310. Cause I thought it would be an upgrade being a lot larger. It just did not pull its weight compared to this. I have an older party box encore that will sync up with this one and they are fantastic together Connectivity is extremely easy. Just have to push the speaker button on the back of each one and they’ll sync up. I’ve heard onn speakers that are bigger than this one and they don’t sound half as good, especially the base on it. ... show more

Excellent Sound and Bass, but Battery Falls Short
Style: Partybox Encore Essential
I bought this JBL speaker about two weeks ago, and as someone who listens to music constantly, I’ve really put it to the test. To give you an idea, I’m in Spotify’s top 0.05% of listeners with over 100,000 minutes of music every year. I listen to music everywhere: in the shower, while working, working out, doing yard work, playing sports—you name it. Here’s what I love about this speaker: 1. Portability and Design: It’s about the size of an air fryer and weighs less than 10 pounds, making it super easy to carry with its built-in handle. Perfect for moving it around the house or yard. 2. Bass Quality: I’m incredibly picky about bass—any rattle or lack of fullness drives me nuts. This speaker delivers. The bass is clean, deep, and powerful, especially in smaller rooms like a bedroom or bathroom. You can really feel it. 3. Volume and Clarity: This thing gets loud—loud enough to fill my backyard, and you can still hear it clearly from 150 feet away. The best part? It doesn’t sacrifice bass quality at higher volumes, which is rare in a speaker this size. 4. Simple Controls: Straightforward and easy to use, which is always a plus. Now for the downside: the battery life. This is my biggest complaint. I always use bass boost and play my music pretty loud, so that could be a factor, but I’m only getting about 3-4 hours of playtime—maybe less. For longer outdoor sessions, I’ve resorted to bringing the plug and running it off power. It doesn’t help that plugging it in is a hassle. You have to remove a rubber cover and wrestle the oddly shaped plug into place. That said, for $200 (I got it on sale), I don’t think you’ll find a better-sounding speaker in terms of power, clarity, and bass. I’ve owned everything from Harman Kardon and Bose to cheaper off-brand options, and this one outshines them all in sound quality. Final verdict: 4 stars. If JBL could improve the battery life, it’d be a perfect 5. But even with this drawback, the sound quality alone makes it a standout choice at this price point. ... show more

Review of JBL Partybox
Style: Partybox Encore Essential
This JBL really delivers, I bought it to be able to have Bluetooth access, I had thought about a new entertainment center but they are just too expensive so decided to look around for something to use that would have good sound quality, I am so happy with my purchase it totally delivers good quality sound. Now I can listen and have good sound quality with any music I choose. 🤗 ... show more
