JBL Xtreme 4 Blue

The JBL Xtreme 4 is a sturdy speaker that produces powerful sound. I can easily take it with me because of the carrying strap. It is quite heavy at 2.1 kilograms, so I prefer not to wear it all day. Sound The bass tones are strong, so I hear the beat and drums clearly. I think higher tones such as vocals sound a little less full. In the JBL Portable app I choose the Energetic Equalizer setting. Now I find the music in balance. I choose what I like to hear and also put together my own settings. Powerful sound comes from the speaker. If I set the volume to 1/3, it already sounds loud in my studio. Ease of use The speaker is slightly larger and heavier than the JBL Xtreme 3. I can easily take the speaker with me with the included carrying strap. I find the 2.1 kilogram speaker a bit on the heavy side. That's why I prefer not to wear it for too long on a hot summer day. For example, if I have to cycle for half an hour and still walk to the beach. The speaker is stable due to the flat piece at the bottom. I therefore place it firmly on any surface. JBL Portable app I personalize the sound in the JBL Portable app. I choose from JBL's various ready-made options or set my own preferences. This way I choose which tones I want to hear more strongly. I turn the low bass tones a little louder and the high tones softer, so that they sound more in the background. I keep the midrange at the default setting. Design The design is sturdy. The bottom of the speaker is flat and has 2 extra supporting rubbers, so that it does not roll over. I think the carrying strap is sturdy and fits the speaker well. There is a beer opener in it, which I think is a handy and nice extra. I don't like the speckles on the sides as much.

The sound is simply great. For a small room you may want a size smaller, but for having a party outside this is perfect. Also great by linking to more speakers for even better sound. Whether you hear the speaker from the front or the back did not differ much, so it is perfect to place centrally. Compared to the smaller JBL speakers and a pair of Harman Kardon speakers, this one comes out well above it. The sound is clear with a nice deep bass. The battery lasts quite a long time. You can listen to music for almost a whole day (24 hours) without having to charge it again, and with the USB C fast charger that comes with it, it will be full again in no time. Also useful if you want to quickly charge your phone.

I have now owned the JBL Extreme 4 for about two weeks and am impressed with this speaker. Sound perception is of course very subjective. I personally think this speaker sounds good, but of course someone else may find the bass way too much. The sound can be adjusted to your own needs using the JBL Signature app. This app contains some suggested sound profiles, but you can also go wild with the equalizer yourself. With these proposed sound profiles, the distinction is clearly audible, which ensures versatility. The battery lasts a very long time, you can even use it as a power bank. The build quality is superb and makes it feel like a premium product (with a premium price). The unboxing is always fun, because everything is neatly packaged and the speaker comes with a nice carrying strap.
