Design and Build Quality:

This “Exclusive” cable is a nice looking audio gear with a braided design. The cable is made of OCC which is a Single Crystal Copper wire material. The cable is made of 8 cores and each core has 19 strands and each core has a thickness of 0.08mm.

The Penon Audio 8 Core OCC Cable is available in two connector options, which is the 2-Pin (0.78mm) variant and the one with MMCX (Micro Miniature Coaxial) male connectors.

The cable has a nice soft TPU coating/insulation in brown color, with an micro-phonic effect of an acceptable level.

The sample I have received is the one with the MMCX male connectors. The connectors are protected by the black metal housings which are also featuring plastic strain reliefs and each connector has left/right indicators (blue for left and red for right).

The 8 Core OCC Upgrade Cable has a Y splitter and a chin slider that are both in black color.

The 8 Core OCC cable has straight profiled headphone housing is available in the 2.5mm balanced (TRRS) and 3.5 mm unbalanced (TRS) variant and is gold plated.

The cable is 120cm long and is showing a great craftsmanship for a product at this price category.

The Sound:

I have tested the Penon Audio 8 Core OCC cable in general with the OURAT Wine and FiiO F9 Pro In-Ear Monitors and want to share now my impressions for this cable in terms of changes/improvements compared to the stock cables of those IEMs.

 

Bass / Midrange / Treble:

The FiiO F9 Pro with its stock cable has average bass speed, while the 8 Strand Upgrade Cable shows better bass speed. The Stock cable of the FiiO F9 Pro has sufficient midbass quantity average subbass intensity, while the 8 Core OCC Upgrade cable shows a noticeable increase in the midbass quantity and subbass intensity. The same changes resulting when I listen to the OURART Wine. The difference in terms of bass speed is more noticeable than the increase of the quantity.

The FiiO F9 Pro with its stock cable shows good midrange clarity, while the OURART Wine has a warm and full bodied presentation with moderate level of clarity. The Penon Audio 8 Core OCC cable is adding additional clarity, airiness and transparency to both IEM’s. Especially the slightly thin sounding female vocal presentation of the FiiO F9 Pro has been showing more intensity.

With the increased airiness of both IEMs, the instruments playing in the background became clearer and resulting in a better separation of the instruments.

The Penon Audio 8 Core OCC cable is adding to the FiiO F9 Pro and to the OURAT Wine additional extension, intensity and brilliance. The treble quantity and airiness has been improved.

The treble emphasis from the violins to the cymbals increased significantly.

 

Soundstage:

The Penon Audio 8 Core OCC cable gives the FiiO F9 Pro and OURART Wine’s soundstage additional breadth and airiness. The soundstage wideness of both IEM’s increased significantly, while the depth remained almost the same.

In addition, the 8 Core OCC cable has achieved better instrument separation and transparency with both IEM’s.

 

 

Conclusion:

The Penon Audio 8 Core OCC upgrade cable was able to improve the sound performance of the tested IEM’s during this review. The 8 Core OCC cable is adding clarity and airiness to the midrange and treble region and has increased the bass speed and intensity in a positive manner.

 

 

Pros and Cons:

  • + Improvement of Clarity and Airiness
  • + Increase of Bass Speed and Intensity
  • + Good Build Quality
  • – None for the price
