Merqury began as an exploration of how Yu9 could further refine and complete the QUE experience. Following the release of QUE, Yu9 received feedback regarding long-term usability, including concerns about the durability of the shell finish and requests for an upgraded cable. With Merqury, Yu9 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.
Sound & Acoustic Configuration
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.
New Cable Design
The cable receives one of the most substantial upgrades on Merqury, moving from the original two-strand construction to a four-strand braided design. The conductors combine 7N OCC copper with graphene-coated OCC copper. This is a new approach for Yu9, selected specifically to complement the sonic characteristics of QUE. In our listening tests, the new cable provides a slightly more open presentation with a greater sense of authority and impact.
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 tips
Yu9 extensively tested a wide range of ear tips before selecting the combinations that they felt best complemented Merqury and further enhanced its overall sonic presentation.
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.
