Shop by sound
Every cable now has a sound profile: what it does to your IEM, and the cables that share it.
More body in the bass and lower mids, a smoother treble. For long sessions and for bright IEMs.
Even from bass to treble, with nothing pushed forward. The safe upgrade for any IEM.
A clearer treble, sharper separation and more air around instruments. For warm or dark IEMs.
Deeper, weightier low end with more slam, without muddying the mids. For bass lovers and lean IEMs.
Voices step forward with more body and definition. For singers, acoustic sets and vocal-led music.
More space between instruments and a wider, deeper image. For live recordings and orchestral music.
