KEFINE Klean SV IEM
A single dynamic driver can keep the presentation coherent, but it usually gives you one fixed tuning. The Klean SV combines a 10mm DLC dynamic driver with three interchangeable tuning nozzles, letting you adjust the sound directly at the IEM without relying on EQ.
10mm DLC Dynamic Driver
The Klean SV uses a 10mm dynamic driver with a DLC diaphragm. The material combines low moving mass with high rigidity, helping the driver respond quickly while maintaining extension and clarity.
A dual-cavity structure gives the driver additional acoustic control. In practice, the entire frequency range is handled by one driver rather than being split across a hybrid configuration.
Three Interchangeable Tuning Nozzles
Three nozzle options let you change the tonal balance without software.
Silver provides the most balanced presentation, keeping some warmth while maintaining clarity.
Gold shifts the emphasis towards greater transparency, detail and upper-frequency presence.
Black gives the low end more weight while softening the upper frequencies.
The change happens directly at the nozzle, so you can experiment with different signatures without touching an EQ.
Silver-Plated Copper Cable
The detachable cable uses high-purity silver-plated copper. The aim is straightforward signal transmission while keeping the cable replaceable rather than permanently attached to the IEM.
The Klean SV uses a standard 0.78mm 2-pin connection, giving you the option to replace the cable later with another compatible model.
Metal Housing
The shell uses a metal injection construction. This gives the Klean SV a rigid enclosure around the driver without relying on a plastic outer shell.
The SV is sold in a silver finish, which is also the colour stocked by Gamer Unlocked.
Two Connection Options at Gamer Unlocked
Gamer Unlocked stocks two versions of the Klean SV.
3.5mm: the standard single-ended wired version for devices with a 3.5mm audio output.
USB-C with Microphone: connects directly to compatible USB-C devices and includes a microphone in the cable.
KEFINE also produces a 4.4mm version internationally, but that version is not currently part of the Gamer Unlocked stock.
Team Opinion
The Klean SV makes the most sense if you want the simplicity of a single dynamic driver but do not want to be locked into one sound profile.
The three tuning nozzles are the main reason to choose it. They give you meaningful control over the presentation without introducing software or additional hardware.
The USB-C version is particularly practical for laptops, tablets and phones without a 3.5mm output, while the standard 3.5mm version keeps compatibility simple for traditional audio sources.
⚠️ Choose the correct connection: the 3.5mm and USB-C with Microphone versions are separate variants. Check your device before ordering.
