Introduction:The KZ ZSN was what I would consider a turning point for KZ. Gone are the days of shrill piercing highs that made them painful to listen to. Many people complained about issues with the highs on the ZS6 but KZ has had a revitalization and is now making exceptional IEMs for good prices again. Wondering just how good the new IEM sounds read on to find out.
Props to KZ they listened to peoples complaints and actually fixing their issues. The ZS7 doesn't suffer from the piercing highs that many in KZ's lineup did. The rolled off the treble earlier which keeps any form of sibilance or piercing from being produced which is good. I think they could have rolled it off slightly earlier just to give it some more detail but I would rather have a little less detail than piercing.
The mids are nice but nothing is standing out to me either good or bad. They have a good amount of detail retrieval in the vocals due to a little bit of sparkle in the upper mids. There is also no bass bleed present which is nice. They do however sound slightly recessed but not a lot. They are good mids but they don't necessarily surprise me. The sound stage is nice and large with a great since of being in a large sound stage. The image separation is also really good with each instrument being able be picked out with no congestion on complex tracks it's the best I've heard in this price range for sure.
Wow these do a beautiful job rendering the bass. The ZS7 manages to bring a large quantity of bass when needed but doesn't overwhelm the rest of the tracks. Like I said before there is no mid bass bleed and these go plenty low. I wouldn't say they are a bass head IEM but they do deliver a nice punch to your music. This is very much appreciated for people like myself who like bass but don't want the rest of the music to be overwhelmed by it.
Fit and Quality:
I have heard that the ZS7 may have some quality control issues with the shells but mine are perfectly fine and look great with no misaligned parts. The fit on these is nice the rest on my ear being held in place with the cable hook which makes them light feeling. Speaking of the cable I did change the stock cable out for a TRN cable because I am not a fan of the metal wire on the cable that comes with the ZS7 but that's personal preference. I personally never got a good fit with the stock cable and the wire was too stiff for my taste.
The ZS7 has managed to come out as a well rounded IEM that can deliver a punch on the low end. There are some negitives like the slighly recessed mids and in my opinion bad cable but overall its a very nice sounding IEM in the sub $50 market.
CCA C10 Comparison:
The CCA C10 has slightly brighter and airer highs that make way for more detail retrieval. Even though they are brighter they still don't come across as piercing. The ZS7's roll off is noticable when comparing the two and you notice a slightly less detailed less airy sound to them. In this case I would say the C10 is better if you want details while the ZS7 is better for people who are prone to piercing or like the rolled off sound.
The CCA C10 excels in the mids. The C10 is more forward and places the voices right where you would want them. The ZS7 is more recessed sounding however they arn't horrible compared to the C10. The sound stage on the ZS7 is bigger and the imaging is better. This one is close on one hand you have better vocals from the C10 on the other hand you have better sound stage and imaging from the ZS7 so pick your poison.
The ZS7 is the winner with this one. The ZS7 mantains a very well controlled bass while managing to deliver a punch to songs that need it. The C10 isn't bad by any means it still manages to deliver highly balanced and well rounded bass that works well. The C10 just needs a little more thump for me personally.
Conclusion C10 vs ZS7:
I would say the C10 is still number one for two reasons. One it's even cheaper than the ZS7 and two overall it delivers a better sound that works with lots of genres of music. I however your looking for something with bass or rolled off highs than go with the ZS7 it's a great IEM if you want a fun sound signature.
