Headphones are growing more expensive because we demand more of them

One of the developing trends in mobile technology right now is the increasing sophistication of headphones, which is also driving a related move to using untraditional connectors like Apple's Lightning port and the new USB-C standard. New research published this month illustrates this shift quite well, showing a 7 percent growth in annual headphones shipments, but a 19 percent increase in retail value. In other words, we're spending more on each pair of headphones, and the researchers suggest that's down to users expecting more.
