Our proprietary zirconia ceramic is cool to the touch, beautifully smooth and strong, and 100% biocompatible and non-reactive.

Coupled with 18k gold, and titanium memory alloy, earKron™ luxury ear-cuffs adjust to any ear for a perfect, secure fit every time.

The Sound of Luxury

App-supported earKrön™ audio ear-cuffs offer all the wireless functionality you need, without sacrificing your individuality.

The audio was designed by world leading sound engineers from the Harman Kardon stable as an 'open-ear' audio experience. They produce a crystal-clear sound, whilst still allowing you to hold conversations and hear peripheral sound when wearing them as jewelry.

earKron™ is not designed to drown out the world, but to enhance your life within it.

Expect Exceptional

earKrön™ is made for a future-facing luxury consumer who appreciates premium quality, exceptional design, and unmatched attention to detail.

The first editions come with a certificate of authenticity, jewelry box charging case, and a maison-quality carry case with crossbody/belt chain – because accessories matter.
