What takes a headphone to the next level? Try professional-grade resources teamed with studio tuning by a multi-platinum producer, recording engineer, singer, songwriter and collaborator. And that’s what Sol Republic brings to the table with Master Tracks XC.

Combining style, lightweight design and durability, Master Tracks XC over-ear headphones ($250) deliver professional-grade sound with a modern headphone design. Tapping into the sonic perfection of world-renowned producer/DJ Calvin Harris, Sol Republic presents headphones that will bring you joy every time you slip them over your ears.

The sound of Master Tracks XC is most simply described as purity and power, the combination of which isn’t traditionally found in the same headphone. It uniquely delivers a harmony of ideal audio transparency, that simultaneously retains power to deliver deep bass, and clean, crystal-clear nuances within a bespoke design that’s effortless and comfortable transitioning easily from professional to personal use, without compromise.

“DJs travel a lot and they produce music on their laptop, on the plane, or in the car,” says Harris. “These headphones were created to have professional sound quality so you can make music anywhere and it will sound just like it was made in the studio. And if it sounds good on the headphones, you know it’s going to sound good at the club.”
