YU9 Merqury

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.

Really excellent audio and build quality

Really excellent audio and build quality, surpassed my expectations for a W-shaped response from an IEM! Delivery time form the UK to the Philippines was reasonable. 5/5 would buy again!

YU9 MerQury - Sublime, with Presence

OMG!!!!!!!!!!!!!!!! The MerQury!!!!!!!!!

For context, I'm not an audiophile at all. I'm just a human being who has the privilege of enjoying sound and music. I'm in this for the experience, with absolutely no knowledge of audio science. My life and the nature around me are my "science".

The separation is so well done. No spillage. Zero muddiness. Everything is in the right dose.

My ear bones can feel the bass. I can taste the bass in my mouth.

The treble is like little rocks of salt sprinkled on top of my sweet dessert. I don't know how to distinguish bass from sub-bass or mid-bass, but with the MerQ, I don't need to. The MerQ bass is complete. A full circle.

The vocals are so beautifully balanced with the music. They sound heavenly. Nothing is missing. Absolutely nothing.

And the soundstage! So spacious, so airy, so wide and light, yet so well-defined and measured. It never feels contained. It's like a free bird flying through this delightful world.

This is ear-listening good.

One word: Sublime.

Sublime with presence. Close to the line, but without stepping over it. Simply beautiful.

Thank you, YU9, for giving me the privilege of experiencing your creation, and thank you, Elise Audio, for the excellent service.

Cheers,
J. "Koi"
