Have you ever wondered why music sounds so different on headphones compared to loudspeakers? It’s because, by design, headphones are not technically compatible with the stereophonic system. That isn’t to say you can’t still get great sound from headphones. Otherwise we wouldn’t be seeing the boom in headphone sales that we've been seeing the past few years (although it’s worth pointing out that some retail stores keep mirrors next to the headphone displays for customers who care more about looks than sound). In this post, I’ll be examining why music sounds different on headphones, and look into a technology that can upgrade headphone sound quality by several notches.
