Mark Levinson No. 5909

With the advantages of beryllium, one of audio's most coveted materials at hand, Mark Levinson set out to build a statement flagship with all the speed, transparency, scale and dynamics in the world.

No. 5909's driver starts with a sandwich driver core of softer material to offer effective damping at higher frequencies, this surface being coated with beryllium for the metal's stiffness, lightness and air acceleration properties.

That means Mark Levinson's driver moves as a perfect piston over all frequencies up to and above its working range – and its small 40mm size just helps further keeping distortion down by staving off cone and modal break-up.

Mark Levinson's prowess in building the ideal full-range, pistonic, driver ensures the Harman Curve is brought to life in realism, and quality. No. 5909's sound profile has been expertly tuned to an acoustic response curve that achieved the highest subjective scoring across listening tests.

Such quality is preserved even as you venture into noisy environments. The battery provides up to 30 hours of active noise-cancellation – comprising three levels that adapt based on ambient and wind noise – empowered by four mics that double as those for your calls. No. 5909 is, in this way, the perfect life companion.

A wonderful way for Mark Levinson's name to manifest in the daily consideration of music lovers, then. Experience No. 5909's full-on fidelity before you return home to one of their Hi-Fi components. Or, view the rest of our Bluetooth offerings here.
