The speaker has great sound long lasting battery and is waterproof I would defently Recommend this speaker

Great quality of sound, good battery and portability. The best choice. I recommend it.

Great speaker for outdoor parties. Booming and clear sound. Connects via Bluetooth or AUX jack. Ability to charge up to 2 devices at once. Approximately 15 hour battery life. Ability to pair with anther JBL speaker for an even more immersive sound experience. Carrying strap included.

The best Bluetooth speaker I ever had. I had the Bose, Beats PillXL,Beats + and HK.

The JBL extreme speaker has fabulous sound, no doubt about it. It is compact, lightweight, and comes with a carrying case as if it is begging to stay with you indoors or out. The back of the speaker has several ports and plugins so that any device can play on it, which is perfect for our variety-of-music-playing-devices household.

Perfect size for pool / practice field. Nice sound, seems to hold charge well

Speaker is very portable, with a rich clear sound boasting strong bass quality not normally experienced in a speaker this size. Connectivity to my cell phone was very simple,

The JBL Xtreme is an outstanding Bluetooth speaker. You will not believe the bass sound coming off this speaker, the sound is awesome. I own just about all JBL wireless speakers (Clip2, Flip3, Charge3 and now the Xtreme). The sound quality improves in the order I listed, the JBL Xtreme being the best of all. I would recommend any of the models listed especially the Xtreme.

This is an awesome speaker. I had previously purchased a Braven Bluetooth speaker (same price range) and the JBL was superior in sound at high volume. I took this speaker to Cancun and it played for over 10 hours at the beach without any issues. It will fill a 20x30ft room with great sound. Many people ask if it's a special order speaker because of its performance. It's simple to sync to any Bluetooth device and the charging use ports are a major plus. Love the portability!! Strapped it on and off to the beach, park, back yard, etc. you will not be disappointed. I spent hours listening to different speakers. I even bought other brand to try out. Eventually I returned them and kept this one.

I have bought and returned at least 6 or 7 Bluetooth speakers over the last year trying to find the best one that I can use at work all day. I returned all of them because I was paying a lot of money for a small speaker with horrible distorted sound and odd sounding bass. Other speakers like the UE megaboom, UE boom 2, Sony SoundLink mini 2, altec Lansing life jacket, beats pill, beats pill xl I had to constantly be adjusting equalizer settings because the sounds were always comming out different depending on what your listening to. But finally after much frustration and time and money spent I found the one. The extreme sounds great, has good bass without sounding distorted, and gets loud too. Take it from someone who has tried many other speakers, and get this one. 5 stars all day

i decided to purchase this after doing lots of research, and watching many youtube reviews. this speakerr gets loud, it has crisp highs and mids with plenty of low end. distortion is a non issue at full power.

We needed a speaker that would be good in a greenhouse that has lots of moisture and background noise. This has been an excellent choice. Good sound quality and it holds up extremely well to the elements. Love that we can link it to our other jbl connects and have sound throughout the yard.

My wife got this for me to replace my old non-bluetooth speaker. I am blown away. I love bose products but this blows bose away. Best portable speaker ever. Bass is awesome.

good sound, good size, good battery life,and is a JBL!!!!

I love the crisp clear sound of the highs and the thump of the lows. It has a sub-woofer on each end which gives it plenty of bass, but it does not go overboard. It also has a strap that attaches to it which is good as it is heavier than some others I've used. Also does not have a case.

This is a great speaker. I got this for camping and fishing trips and it does the job. The speaker is very small and durable which is ideal for me. The sound quality is great and I the battery life is great.

Great sound, size, and battery life. Well put together speaker!

This is a fantastic speaker, it is a great portable speaker with excellent sound quality and lasting charge. Best Bluetooth speaker I’ve owned yet. I love this thing. Really good sound. I can’t stress that enough. If your in the market for a great sounding Bluetooth speaker, this is worth every penny! Highly recommend.

The JBL extreme is the best bang for your buck. Litterally this thing bumps! Cheaper and better than the popular beats pill. Sound quality is amazing. Super easy to connect to your phone. Waterproofing is an amazing add-on and works perfectly. I highly recommend this product to someone looking for a portable speaker.

This is a very nice bluetooth speaker! It is loud and clear, and it is a nice bonus that multiple phones can be connected at the same time. There is also a perk that it can be combined with another JBL speaker through the app so that you have a 2 channel (L and R speaker) sound system. Battery life is great as well!
