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 shells, transparent red faceplates, metal logos 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.

The Ψ (psi) is the main axis to our designs. Being three-way, it was the starting point for others. When tuning this three-driver model we were aiming for the most pleasant musical sound resembling the classical hi-fi and pro-audio equipment from the 70’s and 80’s. Overall sound was meant to be extremely natural, a little bit laid back, balanced, full, pleasing, musical and very faithful in a monitor kind of way.


Lows that are punchy and could get pretty big if the sound engineer had meant them that way. Soft mids, in their vocal range recessed just enough to avoid nasal sound and sharp enough in higher part of the band to maintain punch in snares or grain in distorted guitars. Due to the unique acoustical tuning, highs were kept crispy but not harsh.


Naturalna przestrzeń, doskonała separacja źródeł pozornych, spójna przestrzeń.

The Switch

The switch controls the bass and lower mids (below 1000Hz). 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)
  • w zależności od poziomu i jakości niskiego pasma zawartego w nagraniu (gdy jest wysoka podbicie może zwiększyć jego masywność), gdy jednak bas staje się dudniący i niekontrolowany, w łatwy sposób dzięki przełącznikowi może zostać stłumiony i uporządkowany)
  • w przypadku odsłuchu w hałaśliwym środowisku (w samolocie, metrze, pociągu etc.) gdy zewnętrzne zakłócenia maskują niskie częstotliwości zawarte w muzyce, rozwiązaniem może być ich podbicie
