The sub-$20 In-Ear Monitor (IEM) space is an absolute madhouse, yet CVJ has rolled out a contender that stands out. Today, I’m checking out the CVJ Vivian. Priced aggressively at $18, it’s aiming squarely at the budget-conscious listener. Underneath its distinctive look, you get a single 10mm dynamic driver. CVJ is pitching this as a genuine all-rounder—suited for enjoying your music library and getting an edge in competitive gaming. So, are these budget earphones all flash, or does the Vivian deliver quality sound? Let’s find out.

Design

The CVJ Vivian comes in 2 distinct designs: one showcases an ACG-inspired waifu illustration, while the other has the model name (Vivian) in a stylistic, gothic font. The faceplates have an anodised metal base with a 3-D digital-embossed textured artwork.

Comfort-wise, the Vivian shells feel great in my ears. Despite their relatively compact size, they sit snugly in the outer ear and provide solid passive noise isolation. Furthermore, the smooth, rounded housings rest naturally against the ears, making them comfortable to wear for long listening sessions without any noticeable pressure points.

The Vivian comes with a fabric-sheathed silver-plated copper cable featuring QDC connectors. It feels of reasonably good quality for a budget IEM accessory. However, the preformed ear hooks are quite aggressively curved, which, at least for me, compromises the stability of the fit and makes the cable more prone to tangling. I quickly swapped it out for a third-party alternative. It should be noted that this is actually a modular cable, but there’s only a 3.5mm plug included in the box. You can purchase a 4.4mm balanced plug separately or use any with a compatible 4-pin socket.

Sound

Gear used for testing includes the FiiO Snowsky Melody and HiBy R3 II. Vivian is easy to drive, so there’s no need to worry about which audio source you plug it into.

The CVJ Vivian has a warm, slightly thick V-shaped sound signature with an emphasis on the low frequencies. It aims for engagement and musicality over precision, which is great for immersion but less ideal if you’re after analytical detail or reference-style accuracy.

Bass

The Vivian has an elevated bass response, particularly in the sub-bass region. It can deliver satisfying, visceral rumble—even reaching basshead levels. The mid-bass is boosted too, though to a lesser extent than the sub-bass. Overall, the bass is physical, engaging, and reasonably well-controlled, though it does bleed slightly into the midrange.

Midrange

The midrange presentation is influenced by the powerful low-end. Rather than being merely recessed, the lower midrange has some added thickness. Female Vocals, which rely more on the upper midrange for clarity and presence, are somewhat subdued and sometimes sit slightly behind the bass region. While they retain articulation, they lack the forward projection needed to cut through busier tracks. Male Vocals benefit from this warmth, often coming across as slightly thick, giving them weight but occasionally clouding fine detail.

Treble

The treble is energetic and contoured to inject detail into the lively signature, counterbalancing the boosted bass. It features a noticeable lift at 4kHz, which enhances the attack of instruments, followed by a slight dip around 6kHz that helps temper the overall intensity. The profile concludes with a prominent peak at 8kHz, designed to enhance perceived resolution. It’s a decent treble response that adds some lightness to the sound without sounding sharp.

Soundstage & Technicalities

While the soundstage isn’t particularly large, it’s decent for a budget IEM. What it lacks in dimensions, it makes up for with good positional cues and imaging. The instrument separation is pretty solid and only starts to deteriorate when the track becomes overly complex or features a lot of low-end activity, which can introduce a slight congestion, but this is a minor caveat at this price point.

Comparisons

7HZ Salnotes Zero

The Salnotes Zero has a near-neutral tuning, so it has a very different kind of sound signature. Most notably, the Zero’s bass is much leaner and faster. It’s more controlled and defined but it doesn’t have anywhere near the same kind of physical response as the Vivian.

The Zero’s extra lift in the presence region, coupled with the attenuated bass level make it more detailed than the Vivian. The Zero boasts better resolution and instrument separation, but this technical focus comes at the cost of lower engagement, as it can sound a little sterile or lacking in dynamics.

Moondrop Chu 2

The Moondrop Chu 2 has a brighter tonality, a result of less bass presence and a boosted lower treble. Its bass is leaner and tighter but it doesn’t have as much physicality or impact as Vivian’s lows, which helps to emphasise the sense of air in the treble.

Chu 2’s mids have more clarity but might sound bright or shouty to people who are sensitive to a boosted upper midrange. When it comes to technical performance, the Chu 2 has better detail retrieval and a wider soundstage. However, Vivian’s extra stage depth gives it slightly better positional cues and imaging.

Verdict

The CVJ Vivian is an interesting new budget IEM. It has a bass-forward but surprisingly refined sound that aims for engagement and musicality more than technicalities. It might not have the most detailed sound, but it does well in terms of imaging and positional cues. Then, of course, there is Vivian’s distinct visual design, which will be especially appealing to fans of comics and anime (or just waifus). Overall, it’s a decent entry in the crowded budget space that does just enough to stand out amongst the competition.
