Penon Vortex HiFi Audiophile IEM

  • Handmade,solid and durable
  • Resin shell, lightweight and comfortable
  • Driver characteristics: DLC diamond-like carbon fiber material, the molecular structure is similar to diamond, the resolution and transmission details are precise and neat, clear and natural. Similar to beryllium metal used in aerospace research and high-end speakers, it is a light metal, and the density of DLC diamond-like carbon is comparable to that of metal beryllium. The ideal diaphragm needs to have the characteristics of light weight, proper damping, and small divided vibration. The key point is that the forward and backward delays of the vibration should be just right: vibrate immediately when a signal is received, and stop in time when the signal disappears. Diamond-like carbon achieves a perfect balance in terms of sound conduction velocity and internal impedance, that is, it has ideal performance on forward and backward delay , ultra-high sensitivity and excellent transient response, which can accurately restore sound.

    Treble: the treble is the Vortex’s bread and butter, with this being easily the best treble I have yet heard from Penon Audio. It’s very well extended, sparkly and clear but without any offensive peaks or brightness.

    Mids: to the point where I find there to be very little coloration to the sound. It’s still certainly not neutral as the mid-bass elevation does continue its organic descent for a good ways into the true mids, but in balance with the respectable level of pinna gain the overall midrange tonality is now quite firmly in the “natural” rather than the “fun” category.

    Bass: The elevation is modest and biased toward the mid-bass, with sub-bass being not at all absent but still somewhat rolled off. However speed, tightness, and texture are all impeccable, especially given the price point and driver configuration

    Fast, Precise, Incredibly Well Textured, Vibrant, Clean, Transparent, Dynamic – these are all the words that are associated with Penon Vortex in my mind. It is an incredibly solid performer in a surprisingly small package. The fine microdetails, prominent textures, transparent and dynamic sound, intimate stage coupled with pinpoint imaging – all of them envelop you from all sides, slowly drawing you nearer and nearer to the centre of the music. The more time you spend with them, the more enamoured you become. Penon Vortex is truly a maelstrom of small ingenuities that might not sound much impressive from the get go, I remember I found them a bit bright and thin sounding with a rather lacklustre low-end in the beginning, but the more time I spent, the more trapped I got in its flow, and now I can say this is one entrapment I am not looking to get out of anytime soon.

    Vibrant is what I’m going with. The VORTEX sidesteps much of the regular issues encountered by single-full-range drivers. It’s in the midrange and treble, in how there is a grand separation, but also naturalness at hand. It’s this specific balance of spacial and tonal distancing out into the stage, but also a specific evenness and correctness of the mids. What I’m basically saying is the midrange is not too forward, as found in a few less than average single full-range DD IEM responses. It’s just right! And… was always just right, no matter what cable, ear-tips or DAP I used. This occurs due to there being a character quality we can’t fully change with these adjustments. So don’t worry as the sound of correctness with the VORTEX is easy to find.

    The Vortex surprised me, I see it as Penon diversifying its offering and exploring new ground. The Vortex is a successful neutral-bright set, that’s energetic, airy and has great dynamics. It will recreate instrumental music, especially guitar work with clarity and presence, percussion is weighted naturally and has every texture and hit explored. If you’re a fancier of single DD coherency, listen to a largely instrumental library (especially rock, blues, folk etc) and want a bright and musical set, the Vortex will no doubt catch you in her spin.
