"Surprisingly loud and bass-y."
"The WB4 is a great little speaker for the outside deck hung on the pole of the deck umbrella (i.e. podcasts, YouTube/YouTube TV, background music). I'm not left for "wanting" when listening to it."
"Even the wonderboom 4 sound such better than the willen."

Accomplished_Army660 1.0Of the small ones there is nothing that surpasses the UE wonderboom 4
Ese es tu caso en particular, nada que ver con la calidad y el sonido que brinda al ser tan compacto y su calidad de alta resistencia
archiewaldron 1.0I'm currently traveling around the world with the Flip 7 and love the damn thing. I can't believe how good this tiny speaker sounds and it's definitely one of the few things I couldn't live without on the road. I tried the UE Wonderboom 4 initially but it sounded like a bigger iphone, with no separation between highs and lows. The Flip 7 gives a more "hifi" experience, for sure, with surprising bass and clear highs. (For context, I'm super into hifi having had at various times, Monitor Audio Platinum 100/Proac Response 1sc/Apogee Stage/Audio Physic/etc., and the Flip 7 is a great compromise between SQ and portability. )
bjgis 1.0I have had the Wonderboom 2 and 4 and really like them. Balanced, nice sound.
CivicTypeRLimited 1.0For indoors or just quiet outdoor listening prob the UE Wonderboom 3 or 4 For loudness, boom 2 or boom 2 plus, or motion boom plus
Commercial_Hall_2723 1.0always wonderboom 4 rtings... best speaker in life...
DerinRodoslu 1.0Ultimate Ears Wonderboom 4. It’s stereo, sounds clear and enjoyable, and the build quality is top-notch.
They sound like a mini cinema sound system when paired together! I absolutely recommend it!
_derpiii_ 1.0> Can the wonderboom 2 connect with the wonderboom 4? Nope. I have the 3 and 4 - they can't connect.
Desperate_Stay_5899 1.0All three sound awful. Charge 6 sounds somewhat decent compared to the other two.
dr150 1.0Dude, I'm with you. I was at Costco the other day and played it. Wow, it sounded good! Total steal for $79! And I'm a guy that owns the best of the best in such Bluetooth speakers and tried dozens of the highest rated. I also picked up great speakers at Target as well, such as the Wonderboom 4 for $29, Marshall Acton 3 for $170. I also saw the Extreme 4 on supersale but I already knew that speaker blowed, LOL. I just bought a Brane X during Prime Days to try out. It's going to take a lot to scooch over my HK GP3s in stereo ($83/each during Black Friday)... 🤷♂️
To answer your questions: Harmon Kardon GoPlay 3. That's my proudest BT purchase. $83/each for a universally top-of-the-top rated speaker that goes for over $350. I use 2 in stereo when watching movies on the iPad on the deck. Much more satisfying and balanced than even a whopper JBL Boombox 3 WiFi. A total banger of a speaker when you want to rock out! Acton 3 is absolutely amazing! Grabbed 3 for the bedrooms during Target's blowout sale. I listen to it daily. Powerful yet balanced. VERY(!!) satisfying! It's Amazon's highest user rated BT speaker at 4.8/5 for good reason. 👍 The WB 4 was a Target pricing mistake. They had the WB3 priced at $29 on supersale, and they mis-ticketed the newly released WB4 at the same price. 😄 The WB4 is a great little speaker for the outside deck hung on the pole of the deck umbrella (i.e. podcasts, YouTube/YouTube TV, background music). I'm not left for "wanting" when listening to it. Perfect for car road trips/hotels. There's a reason why the WB4 is NYTimes top rated speaker-- a cheap, supremely portable "do-it-all" device with a 14 hr battery. Hard to argue against it. 🤷🏽♂️
I've pushed just shot everything good mentioned on this board at some point. The WB4 will not leave you wanting. For it's size it satisfies. That's why it's so highly rated and it's the #1 recommendation from New York Times, etc. It's a grab and go that gives enough sound to please Of course, if you're a bass head you'll want a proper sized boombox. But for most listeners, that's complete overkill.
Federal_Register_872 1.0Ultimate Ears WonderBoom 4 for $34 with tax and shipping. Sounds better than the Bose Soundlink Micro I had and was a third of the price.
