CCA CA4 – Fun and energy on a budget!

Hello everyone!
After waiting for some time for the shipping process, i’ve received the CCA CA4 that Sunny have sent to me.
Let’s go ahead!

You can buy the CCA CA4 by clicking on the link at the end of the review!

Just wanna precise that my impressions are subjective and that listening experience can change depending on source, tips and so on.

Test were made on:
– Galaxy S7 Edge Smartphone
– Presonus AudioBOX iONE connected to my PC with no Enhancements actived
– AGPTEK M30B/Benjie S8 DAP
I even connect my Fiio A3 when i need it if i hear some earphones need a little more power.

Technical specs:
Drivers: 1 DD + 1 BA
Sensitivity: 107dB/mW
Impedance: 23 ohm

Frequency Response: 20 Hz – 40000 Hz
Cable lenght: 1.2m (0.75mm Connectors)
Plug Type: Straight gold plated 3.5 mm jack

PACKAGING

Packaging has nothing special: there’s the usual carton package from CCA and KZ which cointains the IEMs, cable and the Starline tips.

CABLE

Cable is one of the new KZ cables which has the same connectors that the ZSN featured at first.
Ear hooks are premade and very comfortable, and the cable seems durable even if not comparable to some more expensive cables. Mine doesn’t feature a microphone but you can find the mic version as well. Jack connection is a L-type one and ends with a 3.5mm gold plated jack.

CONSTRUCTION AND INTERNALS

The CA4 are well made with a nice and clean metal faceplate without any kind of back vent (closed design) while the rest of the shell is made with high quality plastic.
The internal side of the shell features 2 vents, one of which is located just above the dynamic driver.
Nozzle features a nozzle lip and seems assembled well.
Configuration consists in 2 drivers: 1 dynamic driver and 1 balanced armature, a very common hybrid configuration.

COMFORT AND ISOLATION

Comfort-wise, the CA4 are good but not great, at least in my case. I can wear them easily but they start annoying me a little after 30mins. I think probably because of my ear as some friends like them.
I feel other IEMs have a more comfortable shape, probably because this has a little more aggressive shape compared to the very smooth CCA C10/ZSN PRO/ZS10 shape.
Isolation is great, the closed design makes them perfect for on-the-go music sessions while walking in noisy environments.

SOUND

Let’s get into it.
Now the critical factor that decides if something has to be tried or not: how do they sound?
I mainly listen to EDM subgenres, Dupstep, Future Bass, Euphoric Hardstyle, Bass House, Midtempo and downtempo, darkwave, drum’n bass, but i even listen to many vocal tracks, moreover female ones.
I always search for IEMs that have a little bit of emphasis in the lower region, and can sacrifice mids with some recession if they still sound clear and natural. I love vivid and sparkling highs if they’re not at a headache level.
V-shape signature is usually my favourite one but in the last period i’m appreciating a more balanced presentation with less recessed mids, more of a U shape.

Lows: lows are emphasized with an accentuated mid-bass response. Sub-bass has a good amount of presence and i even feel these can be too much for many people. Bass has medium speed and high thickness being a plus for people searching for a bassy pair of earphones.

Mids: mids are strongly recessed, at least to me. Male voices miss a few dB but sound good with the right warmth, while female voices are too much recessed. I think i won’t use these when i’m listening Sia, Florence or stuff like that. Synths take a place in the backseat.

Highs: highs are not on the brighter said but i do not actually feel them dark nor recessed.
I feel they’re just right but i miss some details i find in other IEMs. I can even hear a bump in the very high region that gives some more air in the tracks.

Soundstage has average width and height while depth is a very little above average.
Imaging and instrument separation is surprisingly good, considering that the midrange is very recessed and low region is the real star of the show.

Now some comparisons:
vs KZ ZSN PRO
Considering these 2 are in the same price range, i felt forced to write something about how these 2 compare. The CA4 are more v-shaped than the ZSN PRO, with more emphasis on bass and sub bass but less emphasis in the highs region. Highs are boosted on the ZSN PRO but result in a more detailed experience even if a bit more fatiguing. Midrange is much more forward on the ZSN PRO, making them more suited for vocals and more complex tracks. Soundstage is bigger on the CA4 while is more on-the-face in the ZSN PRO, but this is normal considering the midrange is more forward on the ZSN PRO. Generally, i would say the ZSN PRO is more refined and better as an all-rounder while the CA4 is warmer and more suited for hip-hop and electronic tracks. Both are easy to drive and feature the same type of connection (0.75mm 2pin c-type). ZSN PRO are more comfortable. Isolation is on par with a very little advantage for the CA4.

vs MEMT x5
As i’ve already written in another review, the MEMT x5 were hyped some time ago and i think they deserved considering at that time the price was ridiculously good and they performed well. Now we obviously have better choices, but let’s see if they can keep the fight with the CA4.
Both are strongly recessed, but midrange is a tad less recessed in the memt x5, where female vocals sound better.
Sub-bass is more extended in the MEMT x5 while bass is faster and better textured on the CA4.
Highs are brighter on the CA4 with some more details.
Soundstage is bigger on the CA4, while i cannot say the same thing about the x5 which feature a fairly closed stage.
Considering the x5 is a bullet shape earphone, it can be more comfortable for many people compared to the CA4. The x5 doesn’t have detachable cable and it’s very microphonic. I do not own the new MEMT X5s but people speaks well about the new cable.
Isolation is better on the MEMT x5.

vs CCA C10
Last comparison features a more expensive product from the same company. The CCA C10 cost around 80% more than the CCA CA4, but i thought a comparison could be useful in order to inform people about the differences you could notice making a step up for the more expensive one.
C10 have a more forward midrange, less boosted bass and sub-bass, non fatiguing highs with more details. Soundstage is bigger on the C10, imaging and instrument separation are better as well.
C10 are better performers for vocal tracks while CA4 could be better for people searching for a very bassy and strong v-shaped earphone.
C10 are more comfortable and isolation is on par.
Between the 2, i would certainly pick the C10. If you can make a little step for the C10, they’re way more refined and well suited for more organic and natural listening sessions.

SUMMARY

CCA is coming out with some cheap and good products that i personally like.
The CA4 adds to CCA line a step towards the basshead segment which i used to be a part of.
In any case, the CA4 are not for everyone: they’re cheap and sound very energetic, but i would pick the ZSN PRO instead of ’em just because i feel they’re more refined and better suited for all genres.
The CA4 is still a great product for people searching for a great bass response and i would tip them to everyone searching for cheap stuff in order to listen some hip-on and electronic tracks on the go.
