MUSIC lovers do not typically go to the opera to buy a speaker. But at the Palais Garnier in Paris they now can: Devialet, a local maker of high-end speakers, on November 29th opened a store in the 19th-century music venue to sell its most sophisticated product, called Phantom. Looking like a dinosaur egg, this supercomputer for sound (priced at $3,000) is considered one of the best wireless speakers available. It also comes with a dedicated streaming service for live performances, including some at the Palais Garnier.
This Phantom at the opera is the latest example of how digital technology is transforming speakers, headsets and other audio devices. Once mostly tethered to hi-fi systems, they are now wireless, increasingly intelligent and capable of supporting other services. As a result, the industry’s economics are changing.
