Sivga SV021 Pro V2

A wood-cupped closed-back that Sivga retuned after complaints about honky mids on the original: natural, weighty vocals, full and tight bass, a smoothed non-sibilant treble and a wide stage for a closed-back under US$200.

A good-looking wood closed-back with natural, weighty vocals, full tight bass, smooth non-sibilant treble and a wide stage for the money. The cable is the weak point.

Where it sits

Sonic Compass does not score gear out of ten. Gear and listeners are plotted on the same seven axes, so a review tells you where a product sits — and you can see how far that is from where you sit. A position is a description, not a grade.

Natural, full-bodied vocals and weighty mids with a smoothed treble; he calls it balanced, not V-shaped. High = warm on this scale, so slightly warm of the middle.

DetailTexture Detail

Good treble detail resolution, though not end-game, and the driver mesh smooths the top end. Guitars and vocals clean and natural.

Weighty, tight, punchy bass that goes low without mud; not a bass cannon. Piano and drums exciting.

Very good left to right for a closed-back and easy to pinpoint sounds when gaming; not especially 3D or holographic.

Thin evidence. Dense metal passages hold together and it keeps up at the price, but it loses itself a fraction when the music gets very busy.

ComfortComfort & Fatigue

Called very comfortable in the wrap-up; no sibilance or harshness and he could listen loud without turning it down. No detailed fit or clamp remarks, and the cable is firm and microphonic on some gear.

Natural vocals and piano, 'quite exciting', 'balanced, but not boring', and he calls himself impressed for the price.

Context

Sonic Compass does not grade gear. We plot gear and listeners on the same seven axes, so a review tells you where a product sits and you can see how far that is from where you sit.

The SIVGA Robin SV021 Pro V2 is the revised version of the original SV021 Pro, which came out in early 2026. I reviewed the original a few months ago and heard a weighty mid-range, full bass and a smoothed treble. Many other listeners called its mids honky and shouty, and Sivga then replaced it with this V2. I did not hear that fault in the original, and I did not have the V1 with me to compare, so I cannot say how far the two differ side by side.

The V2 was supplied by Sivga. I did all my listening on a NiPO N2 DAP streaming TIDAL, plus some gaming on a Nintendo Switch. My own preference is a V shape with good bass, plenty of clarity up top and mids that sit back, and I am sensitive to a 1 to 2kHz peak. I roll off at about 12 to 13kHz.

The evidence

Listening journey

Vocals and mids — Natural, with full body and weight, and not shouty or honky at all to my ears. Freddie Mercury's voice is the star but is never pushed in my face, and I heard no forwardness, plasticky or metallic tone. Piano is natural and full, with an excellent timbre.

Bass — Weighty and deep without being muddy. These are not bass cannons, and not ocean-floor deep, but on Somebody to Love the bass guitar went low, stayed clear of the piano and complemented it. On Symphony of Destruction the bass was tight and punchy.

Treble — A smoother presentation that keeps a good amount of detail and is not boring or dull. I heard no sibilance and no harshness on any track, metal or Queen. Guitars on Metallica's One and Iron Maiden's The Trooper stay clean where they can turn crisp on other gear.

Stage and imaging — Very good left to right for a closed-back, and better than some open-backs I have heard. It is not especially 3D or holographic. On White Man the guitar sat off to the right, the vocal sat to the left and the whole band exploded when it came in. Playing on the Nintendo Switch, I could pinpoint sounds all around me easily.

Busy passages — On the dense section of Metallica's One, from about five or six minutes in, I could listen loud without needing to turn it down. It loses itself a fraction with all the activity, but it is not bad for the money.

Critical observations

Where the V2 sits — Balanced rather than V-shaped, smooth and relaxed rather than analytical, with the mids sitting around the bass rather than leaping out. It is not boring.

Build and comfort — Handcrafted zebrawood or beechwood cups, protein leather and matte aluminium frames. I like the look and the feel. In my wrap-up I called them very comfortable.

The cable — Braided and nice and thick, with 3.5mm terminations, but firm, with memory, and it holds its bends. It was very microphonic on the Switch and not at all on the NiPO N2. Sivga and Cendi usually make excellent cables and this is not the best of them. I plan to swap it for another cable.

The driver mesh — Sivga has added a material over the driver. It gives the smoother presentation, and it is a change I could do without, because I prefer more treble detail. Treble detail resolution was good here, though not end-game.

No carry bag — There was no carry bag with my set. I can live without it at this price, though I like Sivga's bags.

Against the original — I cannot compare directly, as I did not have the V1 with me. My memory is that the mids may have been a little more forward on the V1, but I am not sure. Sivga acting on the feedback and fixing it quickly is something I rate.

Read this against your own profile — I like a clean, detailed sound, a good-quality bass and mids that sit back. I found the V2 smooth, natural and balanced. If you want an analytical, cold, studio-monitor sound, do not look here. If you are sensitive to sibilance, you will probably like it.

Honest limits — The unit was supplied by the maker. By ear only, with no measurements, and everything was heard from one DAP (NiPO N2) with some gaming on a Switch. Honky or shouty mids are a matter of ear and gear, so other listeners may still hear them. There was no direct A/B with the V1. Timing and Space had thin evidence and the axes say so. The specs below are the maker's.

Verdict

A good-looking wood closed-back with natural, weighty vocals, full tight bass, smooth non-sibilant treble and a wide stage for the money. The cable is the weak point.

<p><strong>Buy it if</strong>… you want a smooth, reasonably detailed, comfortable, balanced sound; you dislike sibilance; you want a closed-back with good left-to-right separation for music and gaming under US$200; or you like the wood build.</p><p><strong>Skip it if</strong>… you want an analytical, cold, studio-monitor sound; you want the most treble detail and are bothered by a smoothed top end; or you want a strong 3D, holographic stage.</p>
