Hi there PAR fam. Today we’re doing the KZ ZS10 Pro review, one I know many of you have been waiting for. The ZS10 Pro has 5 drivers per side (1 dyanmic + 4 balanced armatures) and features polished chrome faceplates. That’s right, KZ did away with the previous housing and instead have chosen to adopt the ZSN style body. Has it paid dividends? Let’s find out.
This sample was provided for the purpose of an honest review. All observations and opinions here are my own based on my experience with the product.
Tried and tested housings
Great build quality
Energetic, clear signature
Same old tangly brown cable
Aggressive sound will not suit everyone
Sound and performance almost identical to the cheaper ZSN Pro
Package and Accessories
Have you unboxed any recent KZ earphone in recent times? If so, you can skip this part but if not it will just take a minute. The outer sleeve of the box has a colour image of the earphones on the front plus the model number and driver configuration below. On the back is a list of specifications and company information.
Removing the outer sleeve reveals the earpieces secured in a paper-covered foam insert, which is covered by a protective, transparent plastic sheet. Beneath the foam are the included accessories which include a detachable 2-pin cable, 3 pairs of Starline silicone eartips, one pair of generic silicone eartips and a user guide/warranty card.
Build Quality and Design
Available in 3 colours: black, blue and purple, the KZ ZS10 Pro adopts the familiar housings that we saw on the ZSN, ZSN Pro as well as the CCA C10, CCA C16 and probably some others which I’ve forgotten about.
The one physical feature that sets the ZS10 Pro apart from the other models is its faceplates. They are identical to the ZSN variants except this time they’ve been polished to a mirror finish which look quite stunning, at least in my opinion.
We can see the same zigzag pattern that was present on the ZSN, as well as the 3 torque screws and 3 vents. The weight and rigidity of the faceplates makes the earphones feel a lot more premium than their price tag would suggest.
The shells are made from a transparent resin, giving you a view of the single dynamic and quad BA drivers within. A single tiny vent is situated towards the rear of the inner shell. The aluminium nozzles are gold in colour, have a proper ridge for securing your eartips and of course, the protective metal grill which keeps that nasty ear wax from penetrating the housings.
Comfort and Noise Isolation
For my ears, the KZ ZS10 Pro are very comfortable and I could wear them all day long. The shells have a rounded smooth finish all over and fit naturally into the concha. One thing to note is that the edges on the faceplates are very straight-edged and might dig into your antitragus or antihelix (Tragus of the ear on Earth’s Lab).
Once again KZ has supplied their famous brown-coloured cable. This one comes with pre-formed ear guides which I much prefer over memory wire. The same transparent slot-design 2-pin connectors are present again, and I must say, I really like this implementation. Sadly, the stupidly placed Y-split that regularly makes the cable a tangled mess has not changed.
A right-angled and rubberized 3.5 mm plug is the final component of the cable. All things considered, it is a reasonably high-quality cable but I personally switch it out for a third-party option as soon as possible.
Gear used for testing includes the Sony NW-ZX300 and Shanling M5s as portable sources. On the desktop, I plugged the ZS10 Pro into my Arcam irDAC-II which is connected to my PC via USB. The KZ ZS10 Pro is easy to drive and does not require extra amplification. It will work just fine straight out of a smartphone or DAP.
Let me say right off the bat: if you’re treble sensitive then don’t even bother. The ZS10 Pro’s sound is very up front and in your face. It’s pretty aggressive from top to bottom from the slamming bass to the ardent treble. It is a detailed sound and has excellent clarity too, along with instrument separation above and beyond what you would expect from a budget IEM.
The ZS10 Pro doesn’t hold back when it comes to bass quantity; it’s there in spades and boosted way north of neutral. Although it is extremely vigorous it’s also a really well-controlled and high-quality bass. Sub-bass rumble gets physical and will shake things up when you need it.
The mid-bass will punch hard on demand too. It has a reasonably fast attack with a slower decay giving it weight while maintaining control. I found it sounded great on most recordings and excessive on some but even when the amount of bass seems unbridled, the quality of it is always impressive.
The lower midrange is a touch recessed due to the influence of the powerful bass but the upper midrange gets boosted and is well forward in the mix, surpassing even the exuberant treble. Like other recent KZ models, the vocals are free of any graininess and are delivered with clarity, although it might be said the lower mids are a bit on the dry side.
ZS10 Pro’s treble is spirited and lively, coming well forward in the mix and lending to the V-shaped signature. Despite being heavily emphasized the treble is reasonably smooth. But it’s going to be a test for anyone who is sensitive to brightness.
Any sibilance inherent in a recording will be present but the treble is fairly even and without unruly peaks.
The soundstage is moderate in size with a rounded shape. Width and depth are comparable in terms of perceived distance while vocals are fairly close to the listener and therefore more intimate. Instrument separation is above average for a budget IEM and positional cues are good as well.
Tonally these two earphones are near identical. In fact, it’s quite remarkable how similar they sound. The ZSN Pro has a hint more presence at 5kHz, making it more prone to sibilance but apart from that there’s hardly anything else worth mentioning in terms of tonality.
The ZS10 Pro has a bigger stage, better imaging and maintains more space between instruments. Because of its ability to keep things separated it presents a more 3D stage where instruments occupy their own space more, rather than being another part in a wall of sound.
Considering how very close these earphones are in sound presentation it would be hard to propose spending twice as much for the ZS10 Pro. The only way I would recommend it is if you really love the tonality of the ZSN Pro but want slightly better technical performance.
The KZ ZS10 Pro is a good performer in the budget earphone segment. However, it is very aggressive in nature from top to bottom without much in the way of subtlety or nuance. On its own, it is really a good value earphone but for half the price you can get almost the exact tonality and performance from the ZSN Pro, making the ZS10 Pro hard to recommend.
