The Sonos Era 100 is good for listening to music. The speaker has some features to adjust its output based on your room's acoustics, as with most premium speakers on the market. Its balanced mid-range makes it suitable for listening to many different music genres. Since it's a stereo speaker, it has a wider sound than mono-only models like the Sonos One SL, with better instrument separation in the soundstage. Given its bass and treble adjustments, you have some ability to customize its performance, too.
