Construction & Build

The KZ Bluetooth Cable might not be the thickest you can find but does not feel extremely fragile. The finish is rubberized.

The connectors, cable bifurcation and stereo plug are all made of metal with a nice industrial feel. Moreover each connector/plug has a reinforced rubberized end to extend their lifespan.

Microphonics

The KZ Bluetooth Cable microphonics are substantially low. The short 70 cm length of it also reduce the risks of friction and consequential microphonics.

Sound

Differently to normal cables, a Bluetooth cable processes the audio signal from the Bluetooth transmission to the earpieces (actually, the responsible is the chip inside the module). Therefore, some cables may apply some sound modification and some not.

The KZ Bluetooth cable (version 1) conserves the same response up to 4.5 kHz and boosts highs, in their upper range from 4.6kHz onward with an average of 3dB in areas near 4.6kHz and increasing up to almost 5dB extra near the ranges of 10kHz to 13kHz – the exact amount of dB boosting will be limited accordingly to which headphone they are connected to.

This highs empowering can make the KZ Bluetooth cable (version 1) a phenomenal companion for earphones with rolled-off highs or for listeners that would like to get a highs boost on their favorite headphones.
