If you like to use your wireless headphones with a cable when the battery runs out, I've got some bad news: the Solo Pro doesn't have a 3.5mm jack. You can still use them wired, but you'll have to buy a Lightning-to-whatever cable to do it. Apple's quest to kill the headphone jack continues, and it brought Beats along for the ride.
Where the Solo Pro really shines is overall audio quality and noise cancellation. Like other recent Beats products, including the Studio3 Wireless and Powerbeats Pro, tuning is much better here. There's still plenty of bass, but it's not a constant burden that overpowers everything else. The Solo Pro packs some pleasant thump, especially in genres with more low-end tones ̵
A good example of this is Oh, Sleeper's Bloodied / Unbowed . Their metalcore style includes plenty of booming drums and intricate guitar riffs that back a mix of melodic and screaming vocals. There's a range of dynamics as well, so the elements on display are pretty diverse. The Solo Pro keeps things neat, allowing everything to stand on its own – whether that's during a softer sung part or a bombastic breakdown. The clarity is also on display for genres like folk, bluegrass or country where you get more detail in the instrumentation. Acoustic guitars ring out nicely on albums like The Highwomen's self-titled debut and the vocals to envelope you, rather than just sitting there.
