The JBL Extreme 3 delivers powerful, room-filling sound in a rugged portable package. Its 100W output produces rich bass and clear highs across genres. The IPX67 waterproof and dustproof design makes it ideal for outdoor use. Key features: 15-hour battery life Built-in power bank Bluetooth 5.1 with PartyBoost for linking multiple speakers Sturdy carry strap for easy transport While pricier than some competitors, the Extreme 3's audio quality and durability justify the cost for those seeking a premium portable speaker. Its large size may not suit all users, but it's perfect for those prioritizing big sound on the go.

I didn’t get to test a demo model in store so the whole unit is a complete surprise. It’s bigger than I thought it would be. It comes with a carrying strap and it’s because it’s that big. The strap works perfect and it is very important part of the speaker. The photo shows the size next to a standard pen. The battery life is great and compared to other speakers I’ve owned even JBL models it last a very long time. The Bluetooth link up is super easy and after you turn it on the link up is instantaneously. The sound quality is what you would expect from JBL. The bass is very noticeable and the highs are crisp. I’m giving it 4 stars because it’s not very loud. Don’t get me wrong it’s loud but due to the size of it you would think it would be louder. I’ve had several JBL charges and for the size they are loud. Comparing to the Charge and the name Extreme this things should be LOUD but it’s not. If I was able to test it before I purchased it I probably would have looked into louder units.

So portability is grest because even though its big you got your strap throw it over your shoulder and you forget its there, loudness is perfect you might have to put the treble mids and bass up on the app, and switch your phones music to last night and it blasts for sure, bass is great when you have the mids and trebles all the way down (bass all the way up) battery is great, and quality is crystal clear love this speaker, i wouldnt pay 379 i would wait for a sale, mine was 229, take it to work everyday!

I bought this as a birthday gift for my husband. He wanted something portable for both the house and travel. Sound is great. Battery life has held up well so far. It's light enough to be absconded by a 4 year old who desperately wants to test its water resistance. Thankfully we haven't had to test out that feature just yet.

[Employee of bestbuy] This thing is awesome! Still very portable. The strap is awesome. My girlfriend has been taking it with her to work, and it fills her restaurant with music while preping. The battery last pretty long even at loud volume levels. 10/10 would recommend!
