JBLXtreme 4 Portable Bluetooth Speaker with JBL Pro Sound and Convenient Shoulder Strap, IP67 Waterproof, Built-In Power Bank, Black, UK Plug (Type G)

I have lived with it for a few weeks now and can leave a review. Coming from a UE 2 it’s a massive upgrade, very long battery, if you play it in 50% it will last more than a week. It depends how many hours a day you are using it, from my experience I am using it 2-3 hours a day and only charged it once. When it arrived the battery was on 70%. Sound wise now, it’s very punchy, it will put a smile on your face. No matter what the genre it performs very well, nice lows, mids and highs. Don’t expect that Xtreme 4 will replace your hifi system, for an every day speaker you can carry everywhere with you is perfect! You will enjoy it for years! Not too heavy I think it’s 2.1kgs, good built quality, the strap helps carrying it and moving it around. If you can wait and grab it for 30% less as I did in Prime deals etc, it’s a steal, for less than £250 is an amazing Bluetooth speaker, it’s 5.3 so you get great cover from a big distance.

The JBL Pro Sound delivers incredible audio quality with deep bass and clear highs, making every listening experience a delight. The IP67 waterproof rating gives me peace of mind when using it outdoors, and the built-in power bank is a lifesaver for keeping my devices charged. The shoulder strap makes it super convenient to carry around. Overall, the JBL Xtreme 4 is a fantastic portable speaker that offers excellent sound quality and durability. Highly recommend

Amazing speaker just picked up a second one to connect for stereo but just one of these will fill your house with deep bass and great high sounds. Worth every penny.

Great sounding speaker. Quite big to carry around (hence the strap). But not really heavy, just bulky. Sound quality is constant even when playing really loud music, no distortion. Battery life is good. Really easy to control via a phone. Great gift, well received by recipient.

No complaints, sound good, build good. A bit expensive, probably get something just as good and cheaper, but I’m biased, I love JBL products.So happy with money spent and purchase. It’s compact/ portable, Bluetooth good, Similar also got a App to manage the speakerTook this on holiday, it done justice in my hotel room and on the beach. I didn’t get it wet but the sand over it was not a problem

Bass dissappear when put more than 50% volume

Amazing battery and sound quality

This Bluetooth portable speaker comes with a Quick Start Guide (mostly picture based), a plug in the wall charger, and an adjustable carry strap. It's not got any settings on it like bass, treble etc. It does have volume up/down and play (press once to play, twice to fast forward x 2 and three times to go back x 3). Also there is the on/off button, a bluetooth button, and an Auracast button (which joins the speaker to a group of speakers, although these have to be the same model).There is an app, which again is basic and gives you 5 equalizer options, JBL signature, Chill, Energetic, Vocal, or Custom (where you get to play with your own setting sliders). PlaytimeBoost will boost up the volume of the music but consume less battery, although the sound quality sounds more tinny with this option on. I turned the speaker and its Bluetooth on and it paired instantly with my android smartphone with no problems, although I had to remember to press the play button on the speaker! After that I just needed to turn the speaker off and later, just turn it on for it to connect and start playing music.The sound quality is good and more than acceptable to me for an outdoor (waterproof and dustproof) portable speaker, although it can't compare with the indoor-use only speakers I have. 10 minutes charge will give 2 hours of music and a full charge takes about 3.5 hours with up to 24 hours play time (dependent on volume and audio content).Dimensions are approx 28cm wide x 11.5cm front to back x 13.5cm tall. I weighed the speaker (with the strap on) and my scales said it was approx 2.308kg so it's not heavy, but I wouldn't want to carry it around for long. It's quite powerful (see photo of the Tech Spec) although I don't plan on annoying the neighbours and of course you need to be able to connect a music source to it via Bluetooth (I have a spare power bank for my smartphone for prolonged streaming to the speaker).Generally my impression is of a nice quality sound for a practical outdoor speaker that's relatively simple to set up and use.
