I have spoken to the new KZ cable in a couple of previous reviews but for those who might not have read about it yet, the cable is a step up in microphonics and isn’t nearly as sticky as the previous KZ standard. The KZ ES4 is in fact plagued by the same upper mids spike, though it is not so apparent and dissonant as on the ZS10.

KZ ES4 In Ear Stereo Earphones 1DD 1BA Wired Earbuds, Hybrid Drivers 1 Dynamic and 1 Balanced Armature driver Headphone with 3.I tried many genres and found none which sounded wrong, but keep in mind that the signature includes a lot of colouration and that may not go hand-in-hand with genres such as classical or jazz where more fidelity is needed.

It can be an issue and I’m going to say it loud and clear: stay away from these if you think this could be an issue to you. The one item that took a step backward on the cable from the previous generation is the strain reliefs at the jack and splitter (both sides) which are no so short as to be worthless. Well, you have to get used to wearing the KZ ES4 earbuds, just like all the other models ( KZ AS10, KZ ZS6 and KZ ZS10). when a song has fast double bass (death metal), it feels like the kick drum is taking over everything and mid to highs(distorted guitar, screechy vocals) vanish. With a form factor very similar to the KZ ZST , the KZ ES4 offer the same outstanding level of comfortable and secure fit.The cable itself is as good as any I have seen that weren’t handmade at considerably higher cost and with a bit of tweaking would really be a super value. Here again this is somewhat tip dependant as I found I could influence stage dimensions with the bore of the tips. Tries to get into upper bass register and bleed towards mid, but is now in control due to tenmak tips.
