One of the least talked about things on a smartphone is its audio output. Don’t get me wrong, people do talk about it. But compared to camera, battery life, and other considerations, audio output is one of those “nice-to-haves” rather than a necessity. Sure, we love our front-firing speakers, but at the same time, we’ll happily accept a rear or bottom firing speaker if the rest of the hardware is up to snuff. We might ding it in the review with a sentence or two, but that’s about the extent of it.
