The Meze Audio Rai Penta hybrid technology enables delivery of harmonized sound frequencies without overlay of phase issues. For sound from the drivers to reach your eardrums it has to pass from through the housing / nozzle / eartip assembly. The seamless functioning of 5 drivers is enabled by the very specific and precise length of each sound tube which determines the air volume in front of each driver.

Meze Audio’s design eliminates imperfections that you can find in regular plastic tube and dampener systems, which are commonly used in multi driver assembly.

The more comfortable the IEM, the better the listening experience – this is a fact. Serious audiophiles will spend hours on end engaged in their music.

Meze designed the RAI Penta In Ear Monitors to deliver comfort and prolonged listening sessions allowing for a truly immersive experience for you and your music.

Attention to details to an extreme: round, soft edges designed to embrace the natural curves from one’s ear and to fit perfectly.

The high precision CNC aluminium chassis, skillfully milled from solid aluminium, creates the perfect space for the sound to be precisely channeled to your inner ear directly and without distortion.

The Meze Rai Penta work effortlessly with any device due to its low impedance and high sensitivity but to truly enjoy the potential of its painstakingly tuned driver array, we recommend a high resolution source. The response is super high resolution and is above any certificate or standard.

A balanced sound signature with impeccable micro-detailing provides unrivaled realism all across the wide frequency range, from 4Hz to 45 kHz.

Our Take

The Rai Penta is a statement IEM for Meze Audio, and it’s an incredibly well-crafted earpiece, featuring the signature Meze sound: warm, luxurious, detailed, and sophisticated. Unlike most multi-driver universal fit in-ear monitors, the Rai Penta is compact and extremely comfortable, rivaling a proper custom fit in-ear monitor.
