Beats this morning announced that it will be bringing its excellent noise-cancellation technology to its Solo line of on-ear headphones. The Solo Pro are the official followup to the Solo 3, a branding shift that’s in line with its other technologies.

The noise canceling is the same introduced with the Studio over-ear line, way back in 2017. It’s adaptive technology, meaning that rather being tuned to a specific sound like, say, an airplane drone, an array of microphones listen for ambient sound and adjust accordingly.
