KZ just introduced two new in-ear headphones: the ZSA and the ED16. The KZ ZSA uses one dynamic driver and one balanced armature in a housing that seems to be a rounded KZ ZS6, while the KZ ED16 seems more like a pointy KZ ZSR.
The KZ ZSA uses a single balanced armature coupled with a 8 mm dynamic driver that takes care of bass and midrange. The reported frequency response is 7 – 40,000 Hz, with an 18 Ω impedance and a 108 dB sensitivity. There’s no response graph as of now, but it’s legit to think it will have KZ’s traditional V shape.
Housings are made of metal, much like the ZS6, and they come in either grey or black and red (yes, two colours at once!). The cable is the new brass-coloured one also used by the ZS10 and it features the classical 2-pin connector that is widely used in the manufacturer’s line-up. There’s no sign of why the name is ZSA.
The KZ ZSA are on sale on various online stores; Soundphile Review’s partner AK Audio sells them at $21.
The KZ ED16, on the other hand, feature two balanced armatures and one 10 mm dynamic driver; the balanced armatures take care of both the mids and highs, leaving just lows to the dynamic driver. The impedance is rated at 8 Ω, which seems crazy low, but it counterbalances the comparably low sensitivity of 98 dB. KZ promises the earpieces to be matched up to 2 dB difference between channels. There’s no sign of a response graph, however, so it’s hard to imagine how they would sound.
The cable is the same as used on the previous products: simple and covered in rubber with no braiding whatsoever. The housings are made of transparent plastic and come in either blue or black, with the same cursive text style already seen on the ZSR. A feature KZ touts is the passive isolation: the ED16 is able, according to the manufacturer, of reducing external noise up to 26 dB, which would be quite interesting if proven true.
Again, AK Audio has the KZ ED16 on stock at $24 – you can have a look here for additional details. If you use the code “SoundphileReview” while checking out you can buy the no-mic version at 16$ and the mic version at $17. Just select “other payment methods”, write the code in the “leave a message to the seller” and don’t pay until they adjust the price (it has to be done manually).
