Sony says that today’s music is mostly characterized by “heavy-hitting bass lines and dropping beats.” That means you’ll need speakers that can handle those adequately, not exactly the domain of headphones, especially in-ear pieces. Not so, says Sony. At least not for its EXTRA BASS headphones. It is introducing four new such headsets at CES 2017, two wireless, one wired, and one in-ear. All with deep bass notes, convenient smartphone integration and, in the case of one, even noise cancellation.
