What's unique about the brand

Oriolus is a Tokyo-based hifi brand best known for the Traillii IEM, which achieved near-mythic status at ~$6,000 through its unconventional all-balanced-armature design. Using 8 balanced armatures for lows/mids and 4 electrostatics for treble, it delivers unusually natural bass speed and holographic staging. The brand regularly releases Japan-specific editions and focuses on sound-first engineering over flashy packaging.

Traillii Japan Version

  • Positioning: The entry-level unit designed for affordability and compactness.
  • Description: Features a straightforward design with reliable circuit performance that works well for small rooms and modest sonic goals. Compared to other offerings like Mellianus JP or Isabellae, it offers basic functionality without advanced processing and is best for buyers with tighter budgets and simpler use cases.

Mellianus JP

  • Positioning: A mid-range model balancing performance with cost effectiveness.
  • Description: Incorporates improved build quality and refined circuit design that delivers clearer sound details for medium-sized spaces. Compared to the entry-level Traillii while not reaching the high-end sophistication of the Monachaa-1, it provides a noticeable step up in technology and sonic refinement.

Monachaa-1

  • Positioning: A performance-focused unit aimed at enthusiasts looking for richer sound reproduction.
  • Description: Introduces novel signal processing enhancements and a more nuanced circuit layout which offer a marked improvement in dynamic range and clarity. While it outperforms both Traillii and Mellianus in technical complexity, it remains a notch below the advanced features found in the Isabellae and Szalayi series.

Isabellae

  • Positioning: A high-end product engineered for advanced audiophiles demanding greater technical performance.
  • Description: Brings a refined power management system combined with enhanced signal integrity that suits larger rooms and higher sonic expectations. In comparison with the Monachaa-1 and Mellianus, it offers elevated build quality and more complex internal design while still positioned below the flagship Szalayi in terms of complete functionality.

Szalayi

  • Positioning: The flagship offering that features the best available technology in the lineup.
  • Description: Uses state-of-the-art components and advanced circuit design to achieve superior sound fidelity, wide soundstage control, and additional functionalities suitable for the most demanding setups. Compared to all others in the range, including Isabellae's high-end performance, Szalayi stands out with the most advanced features for buyers who prioritize maximum technical sophistication and versatility.

About the brand

Meze Audio is a hifi brand known for their unique Rinaro Isodynamic Hybrid Array driver technology, which provides an immersive sound experience with a frequency range of 3 Hz to 112 kHz. Their headphones feature distinctive design elements like black walnut wood ear cups and detachable magnetic ear pads, setting them apart from typical plastic or metal designs in the premium headphone market.

Our interview with the brand

What are two key technological innovations or strong opinions that differ you from other brands?

Our strongest differentiator is adding the comfort element to the equation. Most headphone models are focused only on technological advancements, forgetting that comfort and ease of wear are also very important factors when choosing an object that you intend to wear for hours on end.

That is why our headphones are specifically designed to be lightweight and to combat any pressure points that can occur when wearing them for long periods of time. 

What's your approach to customer support?

Our clients have the possibility to contact either the dealers/distributors or our support department directly, through our support page: https://mezeaudio.com/pages/contact.

Our headphones are designed to be fully serviceable, so every part is easy to change, in case there’s an issue. There is no glue, just nuts and bolts, so anyone can change any part of the headphone with just a screwdriver.

We are quick to solve any problem as soon as it occurs and in some instances, we do go above and beyond to help our customers. One time, I remember someone was actually wondering if our 109 PRO model's ear cups are really made of wood, so we disassembled a unit, removed the ear cups, broke them into pieces and sent him pictures with the wood pulp, to show that we do use real wood, haha!

What are your favorite tracks for showcasing the strength of your products?

My favourites would be (not necessarily in this order): Sevdaliza - Bluecid, Isaac Gracie - Silhouette of you, and lately, Sleep Token - Damocles or Caramel.

What other products pair best with yours?

Thankfully, there are a lot of good products on the market that have strong synergy with our products, and we are fortunate enough to have great partners in the industry to pair our headphones with.

We also received very good feedback from our customers testing the pairings at different trade shows, and they prefer the following: Chord Dave, Feliks Envy, Ferrum Wandla + Oor + Hypsos combo, the DCS Lina stack, Auris Headonia, Linear Tube Audio Aero + Velo combo, and many many more, these is just top of the mind.
