Love the sound quality it and the base and the fact that you can connect it to another one

Best portable speaker I have used so far. Great battery life and sound

This speaker packs a bigger punch than expected! Extremely clear with no distortion at any volume level. It gets loud, with exceptional balance between bass, miss, and highs. Definitely get the JBL app and use the equalizer- it helps find the correct sound balance for your preferences. Auracast is a cool function to connect to multiple JBL speakers, too! One thing to note - the equalizer defaults to a pre-setting (not custom) when using Auracast, so the sound is slightly different when using that feature with multiple JBL speakers.

It had fantastic volume and sound quality. I use it every day while I am working. It last all day too.

Great JBL speaker. Nice sound and battery life is great. The xtreme models are great to buy especially when I caught this on sale for $299.99

I love it, gets very loud and the battery lasts a long time! Very lightweight to.

perfect for a SMOK sesh , high quality product with a snug and clean packaging, so loud you'll get some ears turning. only thing is price unless its on sale also the sound is directly straight forward so u gotta be Infront of it to hear the best sound quality that it provides , at that point get the portable partyboxes, overall the Xteam 4 is good for traveling if u need something smaller, waterproof and loud.

I loved it, excellent audio and battery life and very good design.

I got this JBL speaker for my fiance as a Christmas gift. He had a cruddy, cheapy brand & it didn't last 45 minutes at work. This Bluetooth speaker rocks! Its lasts days after a full charge. Plus, it is loud which is great for my fiance's factory job. We are big believers in JBL products. We will continue to buy. I highly recommend.

The battery life on this speaker is amazing! super durable and waterproof with great bass.

Very happy with this purchase. I use it for outdoor events and it has good quality and battery last forever. Also the strap makes it super easy to carry.

Great Sound!! Durable!! Looks great!! Easy to use!!

Not only is it super loud but the bass is very clean! No distortion or anything even at max volume. It’s also super durable, it fell off my truck bed (about 5 feet) and there wasn’t a single scratch on it.

Good sound , easy to carry, the battery is good just i really recommended to u guys

Ive always trusted JBL products and this speaker didn’t disappoint! Great sound, easy to connect and great battery life. Will definitely buy another one!

I bought this JBL extreme 4 Bluetooth speaker as an excellent open box item. I received all original accessories with the original box. I once had a JBL extreme 3, Bluetooth speaker and it sounded amazing, but the extreme 4 is a little louder and clearer, and the battery can be replaced with ease. It can be controlled with the JBL app. When you hear the extreme 4 from the distance, you'll think that a floor model speaker is playing, until you get closer and find out that it is the JBL extreme 4, which is a big little speaker.

The xtreme4 has a great powerful sound. Not too heavy so you can carry it around with you inside a backpack which was what I needed to do but I didn’t want a smaller speaker because those do not sound too great. It is the size of a radio too so it does fit inside a backpack.

Very good sound! And insane battery life. Its a lot of fun to bring to parties. But really, its portable enough to bring anywhere

Great sound quality with a nice strap for carrying. Not too heavy. Durable.i have only charged it once in three weeks.

Best amd loudest speaker i have owned. Extremely tough and durable build. Very sleek amd portable design, with included shoulder strap. Would recommend highly!
