Pre-Owned Blue Ella Planar Magnetic Headphones — Built-in 250mW Audiophile Amp

PRECISION PLANAR PERFORMANCE WITH ONBOARD POWER Experience Ella’s planar magnetic design paired with an integrated audiophile amplifier for detailed, impactful sound. Each earcup houses custom double-sided 50mm x 50mm drivers featuring a self-tensioned planar membrane under 50 microns thick for rapid transient response and exceptional accuracy. The large driver enclosures are modeled after high-end speaker cabinets to produce an expansive, natural soundstage. Ella is handmade in small quantities by expert craftsmen to ensure consistent build and sonic quality. BUILT-IN AMPLIFIER AND TUNING MODES Ella is the first headphone to combine planar magnetic drivers with a built-in 250mW audiophile amp, delivering extra headroom and clarity from phones, laptops, or tablets. The amp works with the matched drivers to preserve dynamics and detail. Three all-analog amp modes let you tailor the tonal balance, including a setting that restores the low-end character typical of vinyl-era recordings. FIT, ISOLATION AND CONSTRUCTION The closed-back design and racecar-inspired multi-jointed headband provide a secure, parallel earcup fit that improves isolation, reduces sound leakage and enhances bass response. The reinvented headband suspension creates a consistent seal around the ear for long-wear comfort and stable acoustic performance. SMART POWER MANAGEMENT Ella charges fully in 3-4 hours and provides approximately 12 hours of playtime from its 1000mAh battery. Intelligent power management includes automatic shutdown when not in use, and Ella continues to play music even when battery has no charge.
