The MIRROR represents the current flagship of the company after the CSN and goes a sonically very interesting, in theory very appealing way. However, the potential was unfortunately wasted here and so the MIRROR even draws the short straw for me against the CS8, even if it actually has more to offer tonally.


Visually, I associate the MIRROR more with a penguin wing than with a mirror, but this IEM is probably the most discreet and at the same time the most appealing of the series in terms of design. It looks like it was cast from one piece, is compact and wears very comfortably. In addition, the robust construction makes the MIRROR a value both visually and haptically.

The accessories are not particularly lush and are limited to the most necessary, such as 3 pairs of silicone tips and a budget cable, as is also known from TRN, or BQEYZ. However, we still get a useful cloth bag for storing the IEMs.

The isolation is good and can be further reinforced with foam tips.


CVJ fortunately tries to stand out a bit from the budget chi-fi market by tuning their IEMs. The MIRROR has a fairly flat signature that is more akin to "neutrality" in parts. However, for my taste, they don't manage to eradicate the typical maladies and are not quite consistent with the (apparent) basic idea either.

The bass puts its focus on the mid-bass, which gives it a good punch. However, this is partly also a bit dry and not particularly organic. Certainly a matter of taste. In terms of quantity, I'm more than satisfied and would even welcome a few dB less to play up more neutrally here and give the mids a bit more sparkle. The bass has a pretty good texture and is not limited to a one-note bass. Bassheads certainly won't be happy here, but for me it also hangs in the air a bit, as it seems they couldn't decide where they wanted to go with the bass. The speed is certainly worth highlighting, even if it would like to be a bit crisper and could resolve better.

The mids are somewhat overshadowed by the bass, which brings more energy to the mid-bass in particular than the overall mids. But I don't find that too bad, because I generally like somewhat warmer mids and associated with it a usually somewhat more intimate voice presentation. The MIRROR often meets my taste exactly in midrange, even if I would sometimes like a bit more clarity. Still, I really appreciate that voices don't scream at me, but also don't disappear in the mix. To that end, they basically have a fairly natural timbre (even if the highs are more or less a destructive force of nature). Some might accuse them of a certain lifelessness, where I partly go along, but I don't always need a Himalayan plateau in the upper mids to be happy, on the contrary. Still, I'd like to see 2dB more around 2-3 kHz, or 2 dB less in the bass (60 - 200 Hz).

The treble is now the sword of Damocles for my ears with the MIRROR, because my listening happiness stops relatively abruptly when it goes into the higher frequencies and I only find fewer songs that I can listen to reasonably stress-free. Why the hell isn't the range around 6 - 9 kHz at least somewhat mitigated. Yes the peak is also a coupler resonance, which certainly amplifies the peak, however the energy in that range can't be dismissed either. Apart from the fact that I have seen such a pronouncement so far only with the MIRROR and maybe with the KBEAR LARK (seen in relation to the mids and the bass), the sibilant emphasis and associated sharp sibilants is not only annoying, but partly unenjoyable. This has nothing to do with treble extension, transparency or detail, as it simply sounds artificial and piercing. As is so often the case, a basically good signature is run into the ground again by an exaggerated high-frequency response (we're not talking about a special extension here, because this is rather average), or rather sent into space (Team Rocket sends its regards).Too bad, there was clearly more possible here.

The MIRROR has solid technical characteristics with an appealing imaging and a reasonable stage extension, which is still somewhat artificially extended by the exaggerated high tone. Reasonable for the price I would say.


The idea was good, the implementation less so, at least if you (like me) have a high sensitivity to sibilants and peaks, especially in the high frequencies. I welcome seeing an "experimental" signature under 50€ that deviates from the masses, but then they should have implemented it more consistently. Here was probably more the Asian market in mind, which appreciates a high-frequency emphasis significantly more or even requires it than others.

Unfortunately, even a micropore tape mod can't work wonders here and so only a drastic equalizer helps. With it the MIRROR can be bent then well to right, but that should not be the requirement.

My favorite of the CVJ series therefore remains the CSA.



Here the processing plays a role and the usability of the scope of supply. Additionally the appearance, wearing comfort and robustness.

Here I evaluate for me subjectively the price/performance ratio - does not flow into the evaluation!

Z: No Brainer

A: money well spent

B: all right, you can do

C: gives better for less money

D: overpriced

E: collector's price

Daily life:
Here, I focus on the long-term audibility and whether I can hear it well out of the box. This is of course very subjective and therefore only a minimal deduction or bonus.
