Accessories & Packaging

The CCA CA4 unboxing results in 3 pair of dark colored eartips and the detachable cable.

Everything is packed inside a small rectangular box with a sliding cover – this is nearly the same packaging of the CCA C16, KZ ZS10 PRO, KZ ZSN PRO.

Bass & Sub Bass

The CCA CA4 offers a bass tuning style well-adapted to cover energetic sessions. Still, this is not an outrageously deep nor extremely punchy earphone.

The CCA CA4 can be ranked as a model with a less overboosted sub-bass depth and mid-bass punch when comparing it to other basshead earphones but with a way more intense and boomier response when compared to models with a tighter and cleaner bass.

We find important to highlight that the CCA CA4 has a massive bass variation that will strongly empower according to the amount of blockage that the 2 vents get. As soon as their vents get blocked, a way more congested sound and overcooked bass will be perceived, which can transform it into an overly bassy and congested earphone- to many users this will , probably, be the normal experience with the CCA CA4.

Applying an EQ, an important deepening of it’s sub-bass will be revealed but users should also expect a very bass-centered sound.

Through out our extreme basshead tests, the CCA CA4 handled up to 45% of a FiiO A5 max power with a prominent increment of both rumble and impact but without entering basshead territory.

Mids & Vocals

The CCA CA4 have noticeable mid-bass bleed that can add congestion to it’s lower midrange and deep vocals – mostly when tracks have strong/frequent mid-bass and upper-bass. Nonetheless, their male vocals do not tend to sound distant.

In addition to this, upper mids are clear but can get a bit too crisp with some harshy peaks on some tracks.

Overall, their midrange does not sound overly congested but can get busy, depending on the music being listened. At the same time, it is fair to highlight that their hot peaks might disturb sensitive listeners.

With an EQ, a marginal amount of it’s congestion can sedated but far from showing groundbreaking results. A slight excess of dB boosting can easily make the CCA CA4 too boxy and harsh.

Highs & Treble

The CCA CA4 highs are not too dark nor too bright, sitting in a territory that it could be defined as slightly brightish with a darkening layer on top.

Moreover, the CCA CA4 is not a model that excels at detail retrieval, which could result in lack definition for more demanding listeners.

On songs that are sibilant-prone, peaks can make its sibilance frequently noticeable. Overall, we would say that the CCA CA4 does not particularly shine in these frequencies range.

An EQ can help to remove some of the darkening layer but the personality of it’s highs will be conserved. On the other hand, a much more detailed sound than before Eqing can be obtained.

Sound Leak

The sound leaking out of the CCA is slightly less noticeable than on many average headphone, allowing a bit of an extra margin to crank up the volume before they become too loudly hearable by nearby people.

Sound Isolation

The sound isolation provided by the CCA CA4 is clearly stronger than most normal earphones giving them a good starting to point to reach a near-absolute isolation by dialing up the volume above moderate levels.

Comfort

The curvy form factor of the housings and the light-weighted construction grant a comfortable experience while wearing the CCA CA4 for extended periods.

Response to Equalization

The CA4 could benefit from a proper custom EQ but did not showed any revolutionary response on any given frequency range.
