Wagnus Cable – BlueMoon

Impressions: Wagnus Cable – BlueMoon (2-pin) IEM cable

Website: Wagnus (Japanese only)

Price: 25000 - 26000 (~U$D 210-220)


The design is quite simple but solid enough. It consists of a twisted cable and a plastic cover from plug to plug. The plug is all metal with a plastic cover and quite sturdy, the Y-split and slider are all plastic and a proper relief is lacking. The memory wire earguide is easy to shape and fit. Unfortunately the 2-pin connectors only fit flushed 2-pin sockets, but not recessed. The cable behavior is very average with a strong memory effect and high microphonics. Quite disappointing for the price considering that even 'stock' CIEM cables are so easier to handle.

Fit & Comfort

The memory wire is very easy to shape for a fixed fit. The L-shape 2-pin plug works very well for a more natural over-ear fit. The Bluemoon is very lightweight so very comfortable around the ear. The rest of the cable is a bit springy and kind of annoying when walking around, so the use of a clip is recommended, and also to lower the cable noise.

Sound impressions

Note: Due the non-standard 2-pin plug, the Wagnus Bluemoon was only tested on IEM/CIEMs, with flushed 2-pin sockets; Jomo4, Lear A1d, and R8 to mention some. For Single and Balanced comparisons, the PAW5000 was used as well.

The Bluemoon has a fairly balanced sound, very lively with slight and wide V-shaped presentation. It has a little extra sense of warmth on the lower frequencies and a strong but coherent extra brightness at the upper end adding a better sense of air and separation.

The low end sounds bigger in body with a stronger impact, but tight and better textured. The improvement in extension is definitely a strength on the Bluemoon, and while deeper, its sub-bass response is not the deepest to find. The wider effect gives also place for a both a better decay and a faster, less congested bass.

Midrange is less dominant and relatively recessed but not too distant. It takes a slightly cooler and leaner tonality with a thinner body in trade for better transparency in the sound. Clarity is higher and detail offered in a more effortless way. The main complain would be the vocals being less forward and missing their sweet texture with the Jomo4.

The treble carries greater detail, better resolution and much improved extension. It gives some a bit of an analytical touch to the ED (BA driver for highs) on the Jomo4, which is great for and sounds more effortless and more energetic and less smooth. It comes at price, though, as the Bluemoon might accentuate some sibilance with brighter music.

The most impressive (or more interesting) characteristic of the Bluemoon should be the presentation of the sound. Trying and comparing different aftermarket cables (and at different price brackets), the Bluemoon showed a strong improvement on the stage dimensions. It’s certainly gives a much wider and open sound, and while the height is good, it loses in real depth. Air and instruments separation is very good, guitars, cymbals and upper instruments in general have a stronger edge and notes are generally cleaner, though it has a price, losing in imaging and 3D effect having a more right and left channel separation.

Simply put, the Wagnus Bluemoon cable has some good and bad features. Like the other Wagnus cables I’ve tried it’s a strong microphonic effect, and a simple design and just above average build quality for its price. Moreover, the wider plug and short 2-pin connectors make limits the cable usage with any recessed sockets. However, in terms of sound quality and presentation it definitely improves many aspects of the sound, despite its more lively signature that it can make IEMs have. The wider stage is worth noting, and scales even better with a balanced output. There’s still the lack of availability and the high price.
