I just recieved the Motion Boom Plus, and I thought i’d share my early opinion here.
Physically, the speaker is lightweight, sturdy, and big. The carrying strap is convenient, as is the handle. You can remove the strap. The Motion Boom Plus resembles what it’s name might suggest- a plus sized version of the Motion Boom. Though it does have silk dome tweeters, which the Motion Boom did not have.
Sound:
The speaker is loud- 50% volume fills medium to large rooms. It is a nicely balanced sound with a deep yet controlled bass and clean mids and highs.
App:
The Soundcore App allows for Custom EQ settings, and works quite well. I was able to put a lot more life into the sound with it, and the speaker handled additional bass quite well, with only some distortion with the bass maxed out on the EQ and playing songs above 50% volume.
