Ex Demo/Refurbished legacy version (pre-2022)


We’re clearing up our stock of legacy version IEMs.

After introducing new shell design in 2022 we decided to give new life to several units with in pre-2022 version – black smoke shells, carbon faceplates and aluminum nozzles.

These are too good not to find their new homes. And it’s your chance to get legendary sound in classic shell shape in wonderful price.



These IEMs have served well in our lab as test units. They do have around 30-50 hours of playing time and have been stored in perfect conditions. Last month they have been carefully refurbished in our lab to make sure they are in perfect sonic condition,  restore their shells and make them look and feel as they have been made yesterday!

They come with brand new cables (the old ones have been replaced) and full new packaging (for your enjoyment!).


Our IEMs are build to last. And these Refurbished In-Ear Monitors come with full warranty.



  • Dark Smoke shells
  • 2017A Aluminum nozzles
  • Genuine Carbon faceplates

 Set includes:

  • Packaging Box
  • PELI case
  • SpinFit tips set
  • Cotton pouch
  • Cleaning tool
  • Warranty card


  • Our second in line flagship utilizing not one but two most popular signatures, which can be easily changed with a flip of switch: choose either the “perfect neutral” or the “warm and musical” depending on how you feel today!
  • Introducing PAR (Passive Acoustic Resonator)
  • Four balanced armature drivers
  • Switchable low-end characteristics
  • Utilizing VariBore technology


Our goal was to achieve a powerful sound while maintaining great clarity and precision.


Vented double low-end driver delivers a juicy and powerful bass accompanied by extremely crispy highs produced by HF driver, with lush, distinctive mids placed perfectly in-between. With the switch positioned up, the sound becomes slightly warm and v-shaped. When you flip the switch down, your Model X turns into mid-to-high focused earphones which, thanks to vented construction, maintain the punch and clarity in the lowest end of the band.


Wide, deep, natural.

The Switch

Switch changes level of low frequencies (approx. 8dB<800Hz). You can also use it to make changes depending on:
  • the listening level – to make use of the Fletcher-Munson law (for lower listening levels, bass can be boosted to make it better audible)
  • the level and quality of bass in the recording (if the bass is well recorded, it can increase its strength. On the other hand, if the material is not properly mixed and lows are becoming boomy and get out of control, they can be trimmed down)
  • the external noise levels (if you are using your monitors in a noisy environment: airplane, subway, etc., where the low-end noise masks the lows, you might want to switch them up).
