    To further showcase the differences between these two devices, I decided to play both speakers next to each other. The first track I played was Levels by Avicii. I used my laptop to play this song.
  • No mic or speakerphone functionality on the sound quality setting -“Cancel” button is too difficult to find at the back of the device. To cancel voice input or silent mode on iPhone you would have to press three buttons at once.

Q: How long does the Ultimate Ears Wonderboom 2 last?

A: Also improved on the Wonderboom 2 is the battery life – up to 13 hours compared to the previous model’s 10, according to Ultimate Ears – and we found that number to be fairly accurate. We managed to get 12 hours playing at medium to low volume but if you want to play with Outdoor Boost all the time expect to cut the 13 hours in half.

Q: What makes the UE Wonderboom 2 better than the original?

A: And although the UE Wonderboom 2 looks nearly identical to the original, Ultimate Ears packed in a slew of upgrades that make the Wonderboom 2 even better, like the increased battery life (up 30% compared to the original), better bass response, and the new Outdoor Boost feature that helps the speaker get even louder than before.

Q: Which is better Marshall Emberton or Ultimate Ears Wonder Boom 2?

A: The Ultimate Ears WONDERBOOM 2 is a better speaker than the Marshall Emberton. The Ultimate Ears is better built and has a longer continuous battery life. Its soundstage is better, and it gets louder with fewer compression artifacts present at max volume.

Q: What Bluetooth codecs does the Ultimate Ears Wonderboom 2 support?

A: The Ultimate Ears WONDERBOOM 2 supports just one Bluetooth codec: SBC, which is fine since you’ll likely be taking this outside where the benefits of high-quality codecs would be rendered null. You may connect two devices simultaneously for easy alternating.
