Customer Ratings & Reviews

Best portable speaker on the market for the price. Included strap is great quality and is easy for carrying anywhere. Great sound stage out of a portable speaker as well.

I am very happy with the sound of this speaker...bought it in an open box at a very low price.Great!!

Best Buy is the best place to buy many of you tech devices and countless of other items. I bought many things from them and they always helped and answered all my questions and concerns. I lo their service, is excelle!

Best overall Bluetooth speaker i have ever purchased @ first i was skeptical about paying so much for a Bluetooth speaker but let me tell you i don't regert it one bit the sound the size the crisp vocals and the hard hitting bass not to mention the long lasting battery life it sure is worth every cent. I would recommend to anyone who loves music

I bought a boombox 3. The bass of that speaker was too much for me. It masked too much of the sound when I had to EQ the bass down. So I exchanged it for the Xtreme 3. I like the Xtreme 3 better. It sounds clearer to me. Just make sure you give the speaker at least 30 mins to 1 hrs of playtime to decide if its for you. The 1st time you crank it up it sounds not good till it breaks it even a bit and than its all good.

Sounds loud and clear best thing I brought for my husband.

Great product. I like it so much.. great sound and quality

Great sound and awsome durability bass is tight highs are good even a little more power when plugged in just a good all around speaker

Very excelente product i recommend it overall I recommend buying in Best Buy best price and good store quality products

I never write reviews but had to this time. This is the best bluetooth speaker available for under $300. The Bass is incredible, hard hitting and full, mids and highs are spot on. I have tried many different speakers, all brands. This is the one I am keeping. Trust me, it will blow you away like it did me.

Absolutely phenomenal sound quality, albeit the base could be basier. Easy to connect and set up (like all JBL products) for my dad for him to use our in his shop. It definitely is able to fill the space with amazing sound quite easily, even in his big shop/garage.

Amazing sound. Lots of bass!! Not the prettiest thing but very portable and incredible sound.

Good............... ......................

Totally satisfied with JBL extreme 3 ,, would like to have JBL extreme 4 in my possession for complete Audio coverage in my shuttle bus ,, my passengers love good musical entertainment !!!

This product is has very clear sound even when on full volume and very easy to carry I had it at full charge and had it at the beach for about 6 years playing before it shut off ..

It sounds amazing, went from a flip 5 to an extreme and it’s just too good. I bring it to work everyday it’s the perfect travel size. It’s basically a mini boombox

Excellent, brand new, came in a box. Do more offer like that
