Blue Ella Planar Magnetic Over-Ear Closed-Back Headphones with Built-In Amplifier



The Blue Ella Planar Magnetic Headphones are the only headphones that combine the transparent detail of planar magnetic drivers with the impact of dynamic technology to deliver awe-inspiring sound quality and intense emotion. Ella maximizes the sound of your music using advanced planar magnetic drivers, a built-in audiophile amplifier and large, high-capacity cabinets. And the revolutionary ergonomic fit ensures optimal sound isolation and comfort for the most immersive listening experiences. Whether you’re enjoying the Zeppelin reissue box sets, Pink Floyd on 180-gram vinyl, Radiohead collector’s edition remasters or Neil Young on high-resolution digital, Ella’s radical headphone design reveals new detail in songs you’ve heard a thousand times.

Blue's planar magnetic technology provides the perfect artisanal blend of accuracy and impact. Ella’s 50mm x 50mm drivers feature a planar membrane that’s less than 50 microns thin and self-tensioned for fast response and extreme accuracy. The massive driver enclosures are fashioned after high-end speaker cabinets to deliver a rich, extended soundstage. And to ensure the highest quality standards, Ella is handmade in small quantities by expert craftsmen.

Built-in Audiophile Amp

Ella is the first headphone to offer planar magnetic sound quality with the convenience of a built-in 250mW audiophile amp. The amp pairs beautifully with Blue's custom matched drivers to deliver unprecedented headroom and clarity on your phone, laptop or tablet. Plus, Ella lets you personalize your listening experience with three all-analog amp modes—including one that restores the low-end character to vinyl-era music.
