Billed as ‘the world’s most expensive earphone’, with a price tag of £3,699, the oBravo EAMT-1 model is the flagship in the company’s portfolio.

While the flagship model is exclusive to Audio Sanctuary, subsequent models it imports will be sold through other retailers.

The EAMT-1 features an advanced Hybrid-Planar drive unit specially developed by oBravo. It combines two driver types in one unit, which oBravo claims delivers a sound presentation akin to over-ear headphones, but with the portability of an in-ear.

The coaxial drive unit features an implementation of Air Motion Transformer tweeters with Neodymium Dynamic Drivers, which promises to deliver life-like sound quality, across a wide frequency range.
