Our Verdict
Bang & Olufsen Beosound A1 Gen 2
Ultimate Ears WONDERBOOM 2
The Ultimate Ears WONDERBOOM 2 is a better speaker than the Bang & Olufsen Beosound A1 Gen 2, though they have many different strengths. The Ultimate Ears has a more balanced sound profile out-of-the-box, and it can play stereo content without downmixing it into mono. It gets louder, with less compression present at max volume. Also, its battery lasts for close to thirteen hours on a single charge, while the Bang & Olufsen lasts less than five hours. However, the B&O has a companion app with a 'Beosonic' sound customization feature and five EQ presets, so you can tweak its sound to your liking.
