The name Phiaton signifies high quality sound technology combined with elegant design, a philosophy that is epitomized by the MS 400 Moderna Series headphones. Their attention-getting red-hot design is matched by luxurious audio performance that stands apart from all competitors. The result is a new class of headphone that combines an adrenaline rush of bold styling, opulent red accents and world-class sonic performance – capturing every nuance and note of your music as it was intended to be heard.

One of the first things you’ll notice about the MS 400 headphones is their oversized adjustable padded headband. Not only does the smooth band look great, but it terminates in two richly padded U-shaped earcup holders that can be swiveled 180 degrees – adding flexibility and comfort.


The MS 400’s silky smooth soft leather earpads mean you can wear the headphones for long periods without any “listening fatigue.” You will be enveloped in great sound – instantly feeling the noise isolating performance as the soft pads seal around your ears. This unique closed-ear design ensures excellent audio quality. Like all Phiaton headphones, the MS 400s feature detachable earpads that can be replaced in the event they are lost or damaged.

MS 400


The MS400 headphones are built for extreme strength, and this strength is matched by an ultra lightweight, carbon graphite fiber design (the same material found in many luxury autos, watches and other products) that offers unprecedented durability, with a modern aesthetic appeal. Phiaton has taken the concept even further by encasing the carbon in a high polymer enclosure. The result is better resonance values, deep rich bass, a full-bodied midrange, and sparkling high notes.
With their "fold-and-go" design and durable hardshell carrying case, the lightweight MS 400 lets you enjoy your music wherever you are - at home, in the office, or on the go. The 6.5-oz. headphones are travel-ready, with a sturdy zippered case. There's also a quarter-inch adapter for connecting to your home audio system.
