Penta Hybrid Driver Technology


Each Rai Penta earphone features five individual drivers that operate together in sympathetic harmony thanks to Meze’s Penta Hybrid technology. This new technology enables Meze to deliver harmonised sound frequencies without overlay or phase issues. Before sound from the drivers can reach your eardrums it has to pass from through the housing / nozzle / eartip assembly. Meze’s design eliminates imperfections often found in the regular plastic tube and dampener systems commonly used in multi-driver 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.

Ergonomic Design for Perfect Fit


As we all know, the comfier the IEM, the better the listening experience. Serious audiophiles will spend hours on end engaged in their music.

Meze Audio have designed their Rai in-ear monitors to deliver comfort for prolonged listening sessions, allowing for a truly immersive experience for you and your music.

In typical Meze fashion their attention to detail is outstanding, and has resulted in round, soft edges designed to embrace the natural curves of the ear and fit perfectly.

Ergonomics at its best! Pure comfort with a seamless fit.

Super High Resolution Sound


The Rai Penta works effortlessly with any device to to its low impedance and high sensitivity, but to experience the full potential of its painstakingly tuned driver array, we recommend a high resolution source. These earphones have a balanced sound signature with impeccable micro-detailing and offer outstanding performance across it’s wide, 4Hz to 45kHz frequency range.

Pressure Equalisation System (PES)


Airflow control helps regulate internal chamber pressure both on both sides of the driver assembly through Meze’s finely tuned PES design, preventing a build up of pressure on your eardrum, and on the driver, which can affect sound quality.

CNC Sculpted Aluminium Chassis with Precision Sound Bores

The precision CNC milled solid aluminium chassis with its individual sound bores channels the sound directly to your inner ear without distortion and enables highly accurate high-res sound reproduction.

Meze Audio RAI PENTA Reviews and Awards

After the award-winning Empyrean, Antonio Meze and his team have done it again. The 5 driver Rai Penta isn’t only comfortable, it looks beautiful and sounds like a high-end IEM should sound.

Who needs Madison Square Garden? And if you’re a sucker for precise imaging, you’ll certainly get a kick out of the Rai Penta. Even the smallest gradations in width, depth and height are abundantly apparent. And if you appreciate a truly holographic listening experience, you’ll be hard pressed to find a more colorful soundscape for the price.

It has a beautiful, harmonically complex, and natural sound with a little bit of a bass bump for extra impact. Additionally, it fits extremely easily in the ears and makes for a wonderful listening experience.

RAI Penta has a very powerful driving force. Since it’s so easy to drive, Rai Penta can perform very well with any device, rewarding the listener with a crystal-clear sound.
