Our Take

Antonio Meze has done it again. Hot off the heels of the groundbreaking Empyrean, the Rai Penta explodes onto the scene as one of the very best IEMs in its class. Priced competitively and packed with premium extras, Rai Penta is an outstanding choice for those looking for comfortable, engaging, and neutral earphones.

Read our full review.

From Meze

The Penta Hybrid technology delivers harmonized sound frequencies without the 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 basically determines the air volume in front of each driver in particular. Our design eliminates imperfections that you can find in regular plastic Tube and Dampener systems, which are commonly used in multi-driver assembly.

Anatomical Fit

Ergonomics at its best. Pure comfort. Feeling of airiness and seamless fit. The comfier the IEM, the better the listening experience, this is a fact. Serious audiophiles will spend hours on end engaged in their music. RAI In-Ear Monitors are designed 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.

Pressure Equalization System (PES)

Airflow control helps regulate internal chamber pressure trough our finely tuned PES design in front and behind the driver assembly.

Full Metal CNC Sculpted Chassis

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

Meze Rai Penta

Super High-Resolution Sound Compatible

The 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.

Top Quality Cable to Bring Out the Best

Each wire consists of 20 litz strands. MMCX plugs are top quality and plug termination is rhodium plated for best connectivity and durability.

Super Comfortable and Brilliant Sound

So happy with the fit. I have difficulty finding anything in ear that is comfortable. The Rai Pentas are! I got them on Bloom’s recommendation and couldn’t be happier. I listen mostly to jazz and they are a great match for the more intimate vocal and guitar recordings I like. Check out Tierney Sutton’s latest Paris II with them! I pair them with an A&K Kann Alpha. Also happy with the upgraded, extra balanced cable, as well. 5 stars for Meze, the Rai Pentas, and of course, Bloom.
