JBLXtreme 4 - Portable Bluetooth Speaker, Powerful Sound and Deep Bass, IP67 Waterproof, 24 Hours of Playtime, Powerbank, PartyBoost for Multi-Speaker Pairing (Blue)Recycled Content Certification for Electrical and Electronic Equipment

By far the best Bluetooth speaker you can get in this size.The sound is amazing. (One would expect nothing less from JBL). Plenty of power for a party outside without having the entire neighborhood hear you. The base transducers on the sides add a significant about of lower frequencies that are hard to believe from such a reasonably sized speaker. The highs are clear and crisp the mids have a bit of that JBL warmth ...amazing all around.Dust and water proof.There is an app to let you run some upgrades and adjust EQ settings.That battery just lasts and lasts and is also replaceable (couple of screws).I had a previous version of this speaker, it had a very annoying and difficult to open charger port cover.This one eliminates both the cover and the proprietary charger. The speaker can now be charged via USB-C which automatically detects presence of water. The cover is no longer needed.There is even a bottle opener on the shoulder strap to make this already speaker even more practical and perfect.

The JBL Charge 4 is powerful, clear, and has deep bass. I love how portable it is, and the battery lasts all day—plus it can charge my phone! It’s waterproof and super durable, perfect for both indoor and outdoor use. Definitely worth it if you want reliable sound on the go.

I love this speaker. This little speaker packs a clear, detailed punch. The battery is replaceable, and I love that it is both water and dust proof. The battery life is extrodinary. I do a lot of woodworking, so I acumulate a lot of dust in my work place, so it works great in my wood shop. Where this speaker really shines is outdoors. Outdoors it really opens up the sound quality, enough your neighbors might complain. The bass is booming, but the sound quality and vocals are exceptionally clear. It is definitely worth the price of admission!

Very durable feeling. I bought it for our pool room and it gets nice and loud. Very easy to connect to as well as easy to charge. I have brought it with me on my Ranger as well as on my boat. Holds a charge for a very long time and is great for outdoor use. Also, it looks really cool!

The JBL Xtreme 4 has blown me away. It’s much louder than my previous speaker, and the sound quality is incredible. I’ve taken it jogging, river rafting, and even on vacation. It handled mud, sand, and being fully submerged in water for 15–20 minutes — and still worked perfectly afterward. The battery life also really impressed me; even at full volume, it lasted a solid 6 hours in the sun and water. This speaker has gone through a lot, and I have zero regrets about buying it.Pros:Extremely loud with great sound qualityVery durable — survived water, mud, and sandLong battery life, even at high volumePerfect for outdoor adventuresCons:None based on my use

Another great JBL product to add to my collection! Got for our outdoor hot tub and other situations where I wanted good quality sound. This checked all the boxes. Long battery life, JBL app allows you to control things including 4 preset EQ levels and a 5 band manual EQ!Sounds amazing and is actually very easy to carry or tote around. Battery life is insane!Smaller than an old school "Boombox" but twice as loud with the highs, mids and lows all clean and solid!I would highly recommend this for.anyone who wants portable, loud, clean, weatherproof sound!

I think the Extreme 4 shows us the challenges of making a portable, waterproof speaker sound great. It must be very hard to pull off.I bought the E4 to upgrade from my old JBL flip 5, which still works fine. The sound quality from the E4 is better than the Flip 5, but not by much. Certainly not 4x better, based on price.But the E4 is cool looking, and has nice bass sound. It’s the high notes that get muffled. The equalizer in the JBL app is a nice feature, and is the saving grace here.Nice speaker considering the size, durability and battery life. If you’re expecting high fidelity, prepare to be disappointed.

Five stars for the JBL Xtreme 4 — this thing is an absolute beast! The sound is powerful with deep bass, but still has a perfect balance that makes everything from music to podcasts sound amazing.I love using it by the pool — the waterproof design gives total peace of mind, and the 24-hour battery life means I don’t have to worry about charging it all the time. PartyBoost is a cool feature too if you want to pair up with other speakers. I seriously enjoy every second of it.
