The song in Bose’s QuietComfort Earbuds II commercial is “Because I’m Me” by the Avalanches, off their second studio album, “Wildflower,” which was released in 2016. The Avalanches are recording artists, producers, and DJs, so although they produced the song, they’re not the ones rapping in it. Rather, “Because I’m Me” features vocals from Sonny Cheeba of the rap duo Camp Lo (via HipHopDX).
This is actually not the first commercial in which “Because I’m Me” by the Avalanches has been featured. The song was also in a December 2017 commercial for the clothing brand the North Face (via iSpot.tv). Clearly, brands like to capitalize on its catchiness. “Because I’m Me” is available to listen to on Spotify, Apple Music, and Pandora. The official video for “Because I’m Me” can be viewed on YouTube.
