I just got it yesterday and it can make noise for the whole car. You can hear a little bit of it if you are outside the car door is closed which is honestly impressive to me. My friends have told me that there is more bass in this model of Extreme, if you haven't owned a midsize speaker I would...

I really think this is the best bluetooth speaker for the fact you can change the battery one day when it no longer charges. The sound is awesome. The JBL app has a 5 band equalizer. A big improvement over others.

Pros: Battery life, replaceable Battery, impressive sound, pair 2 for stero. Very sturdy.

Cons: Maybe a little pricy.

Very good quality sound and an incredible battery life. Very happy with my purchase, would strongly recommend this product .

Overall: Recommended! Great product for taking your music with you with high fidelity quality and great high and low end reproduction. Seems well made with a durable casing and nice attention to detail. Impressed by the design and the versatility with all kinds of music types sounding great. Cheers

I was looking for a new speaker and was going back and forth between JBL and Bose. I have always been a Bose guy but this speaker is so clear, clear, and sharp I most likely will be a long time customer. I love having the carry strap just wish it had a smaller handle too. Still five stars.

Absolutely love this speaker! Sound quality and bass is amazing and had used it an entire weekend on one charge. definitely recommend.

I have had my extreme 4 for approximately one month and the sound just amazes me. The speaker has the deep rich signature JBL sound that JBL speakers are known for. The louder the speaker the better it sounds, my football tailgates are so much better with this speaker!

Love the portability and the sound coming from a speaker in its size class. Great bass and clear sound. would highly recommend the speaker.

The JBL speaker is really nice! It works seamlessly with a Bluetooth connection. When it’s charged, the play time is long - we have not ran out of battery yet. I’m guessing about 24 hours of playtime. It is IP68 waterproof. The speaker has subwoofers on each end and the sound comes out all around.
