Meze Audio Rai Solo In Ear Monitors in Silver

Refined electrodynamic driver with UPM balanced piston membrane motion, encased in a durable and ergonomic sintered steel shell.

Power of Pure Music

Rai Solo has been born from our vision to offer entry-level audiophiles a solidly built and great value IEM. Ergonomic design, sturdy stainless-steel shell, refined dynamic driver, all for one purpose: enchanting your senses through a pure listening experience.

In developing the Rai Solo, we looked for a fun-neutral but well refined and controlled sound signature. The strongest correlation between the Rai Solo and the Rai Penta is the similar shape of the IEM. The use of Metal Injection Moulding technology for the body of the Solo made it possible to have a very complex inner shape made in mass production with great accuracy.

Unified Pistonic Motion Technology Exclusive Driver

Wire free diaphragm performing in a symmetric pistonic motion without disturbance from wires.

Traditional Driver Membrane

In a traditional electrodynamic driver the voice coil lead wires are glued to the back side of the thin membrane. This is the major factor of the unbalanced vibration.

Wire Free UPM Design

The new UPM driver eliminates this inconvenience by using a totally different approach: the membrane itself is electrically conductive and, therefore, no wires are attached to the diaphragm. The result is a symmetric pistonic motion through its entire movement, without disturbance from the unbalance created by wires.

Main Benefits

• Low total harmonic distortion
• Clear mid-range
• Outstanding reproduction of low frequencies

Vibration Reduction System

Stainless steel is an extremely rigid material, has low resonance and therefore delivers minimum interference to the vibration created by the driver unit. In terms of audio performance, these advantages contribute to a clean and dark background with well-defined imaging.

The specially conceived shell architecture in conjunction with the steel chassis dampens vibration from the driver unit.

Hidden Power

The Rai Solo works effortlessly with any device due to its low impedance and high sensitivity but to truly enjoy the full potential and advantages of its special driver we recommend the use of a DAP or a DAC if you want to use your phone as a source.
