Meze Audio Rai Penta

Meze Audio
Introducing the Rai Penta: a remarkable in-ear monitor-style headphone engineered to be comfortably worn with the cable draped over the ear.

Impeccable attention to detail has defined the design of this exceptional earphone, which underwent over 3 years of meticulous development to deliver the ultimate product. Its interior boasts an impressive array of 5 drivers working harmoniously in a hybrid configuration. Two dual balanced armature drivers handle the highs and mids with precision, while a large diameter dynamic driver takes charge of the low frequencies, ensuring a truly immersive audio experience.

In the realm of audio enthusiasts, it is widely recognized that a mere assemblage of drivers doesn't guarantee exceptional sound. The acoustics of the chamber, dampening, shape, boreholes, and numerous other factors significantly impact the final outcome. Meze has gone above and beyond to meticulously tune the Rai, ensuring its sound signature is perfectly balanced.

Let's start by examining the boreholes. In the realm of high-end earphones (let's consider the acrylic variety for the purpose of this discussion), manufacturers typically employ small rubber tubes connecting the driver nozzle to the borehole. However, Meze has taken a different approach, engineering the borehole to be directly attached to the driver. This grants them precise control over the volume and diameter of their delivery system, resulting in unparalleled sound reproduction.

Additionally, the Rai Penta showcases a remarkable pressure venting system. Given the substantial volume of air moved by the large diameter diaphragm, efficient venting becomes paramount. To address this, Meze has ingeniously incorporated a machined cut-out on the inner side of the housing, ensuring balanced pressure within the outlet tube.
Every aspect of these headphones has been thoughtfully considered, leaving no room for compromise. Prepare to be captivated by the exceptional results achieved through meticulous engineering and uncompromising dedication.


“Rai Penta is the culmination of 3 years of researching the most ergonomic shape and most vivid sound for a Universal IEM. We could have released it earlier, but again, like with any of our other products, we wanted to make sure it is truly the best we can achieve.”
Antonio Meze, Lead designer and Founder Meze Audio
