With an additional WONDERBOOM 4, you can pair the two to either double the soundstage, or to use them for true stereo sound.
Outdoor Boost
While the WONDERBOOM 4 is designed to primarily be used outdoors; backyards, parks, and pools can be noisy places to enjoy music. Thankfully with the WONDERBOOM 4, you just need to tap Outdoor Boost for louder and more powerful audio playback.

Ultimate Ears Wonderboom 4 Reviews

/: No app Support but was a good replacement

I really Like this speaker. it was time to replace my UE BOOM 2 which I love.

Still no UE Boom Mobile App support for Wonderbooms

It is a great speaker and I appreciate the addition of USB-C... but Wonderboom is still seemingly not supported by the UE BOOM Mobile App, making it (seemingly) impossible to pair more than 2 together. Please do correct me if I am wrong here, but I cannot get more than 2 to connect (via physical button in the middle), and they do not show as an option to pair in the UE Boom app. Seems like every single other UE Boom speaker is supported. Strange to omit this product.

See any errors on this page?

The ANKER 33W 2-Port USB-C/USB-A Wall Charger (BH #ANA2326J211) would be a great power adapter option that is compatible with the Ultimate Ears WONDERBOOM 4 Wireless Bluetooth Speaker (BH #ULUEW4G).
