Product Research


Overview: The Meze Audio's flagship Rai Penta in-ear monitors combine Penta-Hybrid Technology, ergonomic design, and precision craftsmanship to provide an award-winning IEM. The Rai Penta has a removable braided cable, 1/4" and airline adapters, cleaning tool, and 8 pairs of ear tips for the best fit. The IEMs, adapters, and ear tips can be stored in the included hard leather zippered case.

Penta-Hybrid Technology: The Rai Penta in-ear monitors utilize a 5-driver design to deliver a pure, detailed sound signature. The four balanced armature drivers and 10mm dynamic driver each have their own function, and work in harmony without phase issues. The dynamic driver reproduces the lower frequencies that drive the rhythm, while the balanced armatures are individually responsible for human voices, presence, brilliance, and beyond brilliance. The sound from the drivers then passes through precision-milled metal individual sound tubes, each made to a precise length to control the air volume surrounding each driver. The Rai Penta IEMs can reproduce a wide frequency range between 5Hz and 44kHz with less than 1% total harmonic distortion.

Ear Bud Housing: The Rai Penta IEMs feature a high-precision CNC aluminum chassis that precisely channels the sound to your inner ear without distortion. The outer surface is anodized in a deep blue color with the Meze Audio lyre logo and L and R (left/right) markings milled to expose the aluminum color below. The ear buds are anatomically designed with rounded edges to comfortably fit into the natural curves of your ears for long listening sessions. The ear buds have industry-standard MMCX connectors, so you can easily replace the cable at any time.

Ear Tips: The Rai Penta in-ear monitors come with a total of eight pairs of ear tips to help you find the perfect fit and best seal. There are 4 pairs of standard silicone ear tips (XS, S, M, L), 1 pair of double-flanged ear tips, 2 pairs of deep-insertion double-flanged ear tips (M, L), and 1 pair of Comply foam ear tips.

Cable: The 48" braided, Rhodium-plated copper cable has a coating that keeps it tangle-free, and standard MMCX connectors. The cable has 4 wires, each consisting of 20 litz strands. The cable wraps up and around your ear, and terminates into a straight gold-plated 3.5mm plug with a finely-crafted metal plug shell. A 1/4" (3.5mm to 6.3mm) adapter is included, along with an airline adapter so you can enjoy the in-flight entertainment. Optional MMCX balanced cables are available directly from the Meze Audio with your choice of 2.5mm TRRS and 4.4mm balanced plugs.
