While they're called the Solo Pro, make no mistake about it: Beats' latest release is the fourth-generation of their on-ear design. As expected, they add the new H1 chip for hands-free Siri activation, instant pairing with Apple devices, and outstanding battery life. Speaking of the latter, they offer three listening modes: Pure ANC adaptive noise cancellation, a transparency mode that lets you hear your surroundings, and extended power, offering up to 22 hours of ANC playback or 40 with the active tech turned off. The new design also exposes the metal sliders, gives all surfaces a matte finish, and employs all-new ear cushions with added surface area for a more comfortable fit. The result is a headphone that's still recognizable as Beats with a more refined, mature look.
