Design-wise, the Rai Penta IEMs denotes an exquisite vibe through its sleek and stylish body aluminum which surface has undergone a process of high-endurance anodization, the full metal CNC sculpted chassis well thought-out to ensure the perfect connection between drivers and your inner ear without distortions and loss of definition.

The sound precisely directed into your ears bear no twists, while the inner chamber remains well-aired due to a pressure equalization system (PES) which uses airflow to regulate the pressure inside of it.

Advantages & Disadvantages of Meze Audio Rai Penta

Featuring one of the most impressive driver configurations that are capable of ensuring an emotional and flawless sound reproduction is one of Rai Penta’s main competitive advantage against other high-caliber hybrid IEMs; And while the sound could be deemed as tight, balanced and neutral enough, the mass of details and clarity is the biggest treasure.

The team of Meze Audio has scrutinized over a few years the best options in regards to the ergonomics as such to make available to you one of the most comfortable earphones which ensure good noise isolation and no sound leaking. But because they’re conceived as universal in-ear monitors, the Rai Penta does provide a comfy seat, although the ambient sounds can sometimes make their way past the metal tubes.

I haven’t touched even lightly the subject of “inside the box“, and I must admit the package is truly impressive, containing a complete bundle of accessories and tools, one of the most impressive is an audiophile quality MMCX braided cable which is so refined, elegant and luxurious, it looks as if it cannot ever break.

  • Impressively large spectrum (5 Hz – 45.000 Hz)

Experiencing the full of fervor music that consists of profound details rarely heard from even some top-end IEMs should be a “must do” on any music lover’s list, even if you don’t necessarily buy the Rai Penta earphones.

The vocals of one of my favorite singer known for being able to “scream like a demon and sing like an angel“, Chester Bennington never felt so intense and with such abundant details or intelligibility as he reached high-pitched notes screaming in the “Given up” from the album Minutes To Midnight, or “Lost in the Echo” accompanied by the feeling of rumble and the depth of the sub-bass which are provided in moderate volume by the dynamic bass driver.

With a price almost as much as gold, the flagship IEM Rai Penta portrays as a real asset in one’s collection. They do have a dangerously charming musicality, and so the high-class in-ear monitors make their owners proud of both engaging and inviting music, while also having ensured a powerful, yet revealing sound.
