Brilliant performers hear music differently. Thanks to Astell & Kern's collaboration with John Harvey Audio on the Rosie In-Ear Monitor Headphones, you can too.  John Harvey Audio has built in-ear monitors for some of the biggest and most respected artists in the music industry. Aerosmith, Guns N’ Roses, Van Halen, Lady Gaga, Foreigner, Linkin Park, Alicia Keys, Rob Thomas, Bon Jovi, Godsmack and, just about every other big name in the industry rely on the folks at John Harvey Audio to produce accurate, high-quality, and durable in-ear monitors. John Harvey Audio’s expertise combined with Astell & Kern's philosophy of "providing the original sound" lets you experience your music the way the artist intended you to hear it -- crystal clear and distortion free, anywhere you go. 

Cutting Edge Audio Technology

Groundbreaking artists demand groundbreaking quality. Why should you settle for anything less? Now, Astell & Kern and John Harvey Audio are giving you the opportunity to hear the same thing your favorite performers hear. The JH Audio Rosie In-Ear Monitor Headphones are equipped with soundrIVe technology. These dual Low, dual Mid and dual High drivers give you the broadest frequency range imaginable, and the variable bass control lets you control how much bottom-end you hear…from a little low-level bump to a chest pounding thud. These headphones provide the listener with truly dynamic detail, free of distortion. 

Made in the U.S.A.

These Rosie headphones are built in the U.S.A., using old school American craftsmanship and cutting edge technology. Each Body, Cap and Sound bore is built out of one ultra-durable, lightweight piece of aluminum with a Carbon Fiber Logo Plate insert. The earpiece connects securely with a 4-pin aluminum cable that protects it from sweat and the environment. Technology aside, the story on these headphones is simple – Rosie sounds so good if you close your eyes you will think you are in the studio with your favorite artist. Simply put, Astell & Kern headphones are the definition of high performance audio.
