KZ ZS4 In-ear Earphones Review:

Design & Comfort:

The KZ ZS4 In-ear Earphones is practically just like the previously-released ZS3. The shell is formed of plastic, either red or black. KZ cursed with a tried-and-true approach – the ZS3 was quite successful product, so a rehash could indeed work (as they assert in Italy: never change a winning team, though there are limits of course). Each earpiece is labelled with the channel name written in rough cursive and therefore the text “hybrid technology”. The shape is ergonomic, within the sense that the shell should be shaped following the form of the inner pinna so as to maximise comfort. during this sense, KZ followed an equivalent approach used with the KZ ZSR – except with different shaping that ought to make the shells easier for a wider audience. The cable is removable and uses 0.75 mm 2-pin connectors, which are a typical within the industry; the sockets on the earpieces are recessed and wish cables that take this into account: employing a cable like the Yinyoo 6-core copper cable isn't possible due to the recession, so a cable like the Yinyoo 8-core SPC cable or Kinboofi 8-core SPC cable with a protruding connector is important . additionally to the present , the very shape of the shells makes it almost mandatory to use cables with an L-shaped connector. Comfort is quite decent, and that i can wear the KZ ZS4 for a few hours before I feel any quite fatigue. The ergonomic shape work fine with my ears and adapts to my pinnae almost perfectly, though it could possibly be an obstacle to comfortable wearing for a few . Ears all differ from each other , therefore the heavily ergonomic shaping of the shells may instead be detrimental if one’s ears are shaped differently. Comfort is actually incredibly personal, so take my comments with a pinch of salt!

Sound & Specs:

As usual, we used several sources to undertake the KZ ZS4 out. Among them are: a Topping DX7, a Topping D30 feeding a Venture Electronics RunAbout 2.0bl, a Venture Electronics Odyssey and a Cayin N5ii. I used a Yinyoo Brown Cable with a 2.5 mm balanced connector and an iFi IEMatch2.5 (with adapters where needed). The sound signature is heavily V-shaped, with powerful lows and prominent highs that surround recessed mids. Bass is particularly notable in being emphasised, almost excessively so, and treble becomes piercing and really fatiguing. In terms of technical ability, the KZ ZS4 isn't the simplest you'll find: soundstage is comparatively small and it never takes the “in-your-head” sensation out of the equation; imaging is rough and can’t place instruments accurately on the stage, with loosely defined positions that are just left/right/centre most of the time; instrument separation is basically basic and doesn’t allow one to differentiate nuances and multiple instruments in congested tracks.

Materials and assembly:

Look KZ ZS4 strange. It’s strange for those people who are used to the traditional streamlined forms of earbuds. The case of the headphones seems too large and angular, even somewhat brutal.
