Not wowed by this one
Was honestly a bit disappointed with this speaker. The sound was “ok” but not as rich as the little speaker I bought from Anker for about £30. The outdoor mode oddly made everything sound very tinny. Given to the daughter to use and abuse - I’ll try again with something else.

Basically a wonderboom 2.
It's basically a wonderboom 2 the only difference is the podcast mode and outdoor mode. It's got the same sound quality and it says it lasts for up to 14 hours mine only lasted 4 hour's total rip off. Way Overpriced just to call it a wonderboom 4 it's definitely not.

Bought my first Wonderboom 4 a week earlier - I was shocked such a small speaker could produce such levels of volume incl deep bass - Hats off to Logitech :0 The waterproof aspect pushed me over the edge to buy one. Turns out It's a great coffee table speaker - and packs an impressive sound footprint. The size makes it easy to place locally for any sitting-reclining situation - allows keeping the sound levels lower so that you impact others less - and yet get great bass performance. Alternately you could crank it up and be amazed or take it outside and adjust one of the 3 EQ settings to "Outdoor LOUD mode". Although default mode is better for bass. After a week of owning one I "had" to order another to get the full stereo support. It was totally worth it, and would recommend these speakers to anyone looking for a super big sound in a tiny package.

It's easy to pack around and has pretty good sound for such a little guy. Primary uses are music and audiobooks and the sound quality good enough that I'm satisfied. It's not Bose, but it sure ain't bad. I use it in the shop, out by the pool and when I'm gardening. Outdoors the sound travels a bit better if there is a wall or something solid behind the speaker. The loop makes it easy to carry or hang up and the 360⁰ sound means less fussing around with location and direction. Connected to my Android, playing on Spotify, I can crank it all the way up with no distortion or crackling. But, I only did that this one time, so I could note it in the review. It's pretty freaking loud. It's solid with a rubber cap on both the top and bottom. In case of a drop, those could be lifesavers. I've never tossed it in the water, so cannot attest to it's water resistance. It connects quickly and easily to any Bluetooth device and the buttons on top provide easy access to pairing, pause and power. It will power down if left unused for a few minutes to preserve the battery. That's a nice function. I'm not wild about the HUGE volume controls on the front. I think they're ugly and detract greatly from the overall appearance of the speaker. Overall, good value for the money.

These speakers are friggin awesome. Got one for each of my parents for their birthdays this year. The audio is crystal clear and it also gets very loud for its size without compromising the audio quality. Great for both music and podcasts etc. Also love that you can attach a carabineer to the speaker so you can hook it onto your pants or backpack etc and have the speaker effortlessly follow you around. The different settings/features are also really cool and handy. Would definitely recommend this product and honestly any product from the Ultimate Ears speaker line as in my personal opinion this line of speakers is the best line of portable speakers I know of or have ever heard. They're priced well too. I mean they aren't super cheap but they aren't overly expensive either, it's kinda right in that sweet spot. If you've got the money and you're looking for a portable speaker, look no further than this line because the sound quality and loudness (without distortion) you really won't find anywhere else especially for these prices. I know I'm starting to sound like a UE shill at this point lol but honestly I just really do love and admire their speakers and don't think they get the credit they deserve. Anyway hope this helps!
