We are reviewing the KZ ES4 the latest release from KZ with a dual hybrid configuration, detachable cables and plastic housings.
The KZ ES4 is the newer updated version of the KZ ES3, inheriting some of their main technical specifications like: dual driver, plastic housings, detachable cables.
The KZ ES4 features 4 drivers in total, distributed in 2 per earpiece. The dual driver setup includes 1 balanced armature and one 10 mm dynamic driver, each driver will independently be responsible of reproducing different audio frequencies – the dynamic driver will take care of the lower end while the balanced armature will resolve mid and upper frequencies.
The KZ ES4 belongs to the newest generation of KZ in-ear monitors and shares some design similarities with the KZ ZS10, like the transparent housings and the characteristic divider board with the KZ logo which can be found inside the rear section of the housings.
The form factor of the earpieces share some of the curvy shapes of the KZ ZST and KZ ZS10 but have a rear housing’s design that (if seen flat) looks nearly identical to a guitar pick.
The KZ ES4 durability is inline with all KZ earphones from the last 2 years – that are built with the same materials. Expect the same rugged and well-built construction of the KZ ZS10, KZ ZST PRO and KZ ED12.
The cables are the same one that comes with the KZ ED15 and KZ ZS10 with a dual double helix braided design and very rubberized finish. The connector of the cable is the same bi-pin 0.75mm of all KZ earphones with detachable cables; specifically they use the angled connector (like the KZ ZSR, KZ ZST and KZ ZS10) and not the straight connector that came with the KZ ZS6, KZ ZS5 and KZ ZS3.
The KZ ES4 price is lower for the KZ ES4 mic-less version, but only marginally cheaper.
The KZ ES4 is compatible with Android and Apple devices.
