Limited Edition to 399 Units

Merqury began as an exploration of how we could further refine and complete the QUE experience. Following the release of QUE, we received feedback regarding long-term usability, including concerns about the durability of the shell finish and requests for an upgraded cable. With Merqury, we revisited the exterior finish, cable, and ear-tip pairing while retaining the core design of QUE, with the goal of creating a more complete overall package.

Exterior Upgrade

Merqury features a brighter, high-gloss finish. The metal faceplate is left uncoated, preserving the natural CNC machining texture and allowing the metallic surface to appear more vivid and reflective. This also eliminates concerns associated with long-term wear of a coated metal faceplate.

Upgraded QUE

The earpiece itself and its original acoustic configuration remain unchanged from QUE. Merqury is therefore not a retuned version of the original earphone. The audible differences primarily come from the new cable and the revised selection of ear tips.

Cable Aesthetic Design

The CNC-machined metal hardware on the cable has also been redesigned to better complement the design language of QUE / Merqury, creating a more cohesive visual identity across the entire product.

Ear-Tip Selection

We extensively tested a wide range of ear tips before selecting the combinations that we felt best complemented Merqury and further enhanced its overall sonic presentation. Different ear-tip selections are provided for the Chinese and international markets, reflecting differences in listening preferences and tonal tendencies between the two markets.

Divinus Velvet Eartips

Merqury comes with DIVINUS VELVET ear tips. The VELVET tips deliver a more impactful low end while enhancing the sense of dimensionality and layering. They also offer better separation and resolution of complex musical passages, allowing intricate arrangements to be presented with greater clarity.
