Eleven XI Audio Eleven Audio Broadway Battery-Powered Fully Balanced Class A Headphone

Designed for listeners who value natural tone, precise detail retrieval, and effortless musical expression, Broadway™ delivers a remarkably smooth and immersive headphone experience.

Broadway™ uses four replaceable Li-Ion batteries as part of its power supply architecture, dramatically reducing AC line noise and providing an exceptionally clean power foundation.

The amplifier can operate for 6-11 hours on battery power alone, or remain connected to AC power for continuous listening while maintaining the same highly refined sonic character.

Accepting balanced XLR inputs only, Broadway™ features a four-channel fully balanced amplification topology with direct signal paths to the balanced headphone output.

With 1.5 watts of pure Class A power into 32 ohms, Broadway™ provides smooth, effortless drive capability while preserving fine detail, tonal richness, and spatial realism.

Developed with ABYSS Diana series headphones as a reference, Broadway™ was created to complement high-performance headphone systems with a natural and engaging sonic character.

The single-ended Broadway S is specifically tuned for low-impedance, high-sensitivity headphones. The connectivity features a pair of RCA inputs, while outputs are updated to an XLR 4-Pin and a 6.35mm stereo jack. Gain, sonic quality, and drive capability have been completely re-engineered and optimized, allowing a wide range of low-impedance, high-sensitivity flagship headphones to perform at their absolute best.

Optimized for: Sennheiser, AKG, Sony, Grado, Fostex, Final Audio, Denon...
