Committed to changing the world one listener at a time, SOL REPUBLIC announced today its first professional-caliber headphone: SOL REPUBLIC Master Tracks XC, studio tuned by Calvin Harris. With sound that's acoustically accurate for music artists to use in the studio, and style, lightweight design and durability for use everywhere else, Master Tracks XC over-ear headphones deliver professional-grade sound with a modern headphone design. Tapping into the sonic perfection of multi-platinum producer, recording engineer, singer, songwriter and collaborator Calvin Harris, SOL REPUBLIC presents the pinnacle headphone for both music creators and music lovers. "DJ's travel a lot and they produce music on their laptop, on the plane, or in the car," said Calvin 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." Master Tracks XC produce an extremely dynamic, sonically accurate and shockingly powerful sound signature with incredible vocal presence that retains critical details in the high, mid and low ranges. It offers an unprecedented combination of audiophile acoustics, high-end, club-level dynamic power, and rich, sophisticated styling in a headphone. "Calvin Harris is an award-winning producer. He has an impeccable ear and understands sound well beyond most music professionals," said Kevin Lee, CEO and Co-Founder, SOL REPUBLIC. "Together we identified everything we'd want in a studio headphone for modern music producers. The design, custom tuning and myriad of details required took more than a year to develop, but were paramount for the quintessential studio headphone. The result is a headphone unlike any we have ever created. The style is sexy and the sound is so powerfully pure, you won't just hear everything the artist wanted you to hear - you'll feel it." SOL REPUBLIC engineered a new Sound Engine design for these Master Tracks that delivers both the transparency and acoustic accuracy that music creators require as well as the dynamic music punch and emotion music listeners love. The result is the new XC Sound Engine that has the full range of music, which reproduces super-deep, low-end bass as well as the extended high frequencies. Beyond bass, perhaps the most impressive feature is the XC's mid range. Mid range is a critical part of the music experience and sounds amazing when done well. Master Tracks XC's Sound Engine delivers an unbelievable strong and accurate mid range, without the distortion and resonances that muddy up the sound. It delivers a level of music realism that music producers will appreciate and music lovers have probably never heard before in a headphone. SOL REPUBLIC's XC Sound Engine is engineered with a full throttle of dynamic power that moves super-fast. This allows for all the "attack" the artist and engineers intended, delivering a bass punch without the bass boom that is often criticized in bass-heavy headphones. 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. As important to the headphone as the sound, the style of the Master Tracks XC design pays homage to the professional recording studio. With a smooth, slim-line finish, Master Tracks XC samples the warm tones of the wood, walls and furniture found in legendary studios around the world. For the music artist or fan who celebrates the smallest details, the Master Tracks XC has an on-trend 'singularity red' satin finish and micro-suede headpad with studio upholstery-inspired accent stitching, which completes the headband's progressive design. A lightweight construction and super-soft ear cushions with perfect tension set them a world apart from traditional, bulky and heavy studio headphones that become painful to wear after days in the studio. Whether you're cutting a track or just kicking back, Master Tracks XC's can be worn comfortably for hours on end. Constructed with SOL REPUBLIC's legendary advanced polymer compound, the FlexTech SoundTrack headband on Master Tracks XC headphones can be tossed, twisted, bent without breakage and is backed by our exclusive 1,000 day no-breakage guarantee. And just like all other SOL REPUBLIC Tracks headphones, Master Tracks XC is compatible with other SOL REPUBLIC Tracks Sound Track headbands, cables and Sound Engines enabling you to create a completely unique look anytime. Rounding out the incredible attention to every detail from in-studio to anytime, Master Tracks XC come with a six-foot rugged cable, with a five-inch coil and quarter-inch adapter. Ideal for professional use, the quarter-inch adapter can be secured on a metal arm, so it's never lost when you go from the studio equipment to your phone. Also in a matching 'singularity red' finish, the MFI cable has a three-button mic and music control to complement any accessory device. Additionally, the indicators, including LEFT and RIGHT jacks, glow in the dark so that they are easy to read in a low-light studio environment.
