TANGZU Wan'er S.G II Bass Version (Lion Edition)

TANGZU Wan'er S.G II Bass Version (Lion Edition)

A $20 'Bass Version' of TANGZU's warm budget favorite — best known for its accessory bundle, with real arguments over how bassy, how bright, and how comfy it actually is.

The Wan'er S.G II in its 'Bass Version (Lion Edition)' — the 'Red Lion': a ~$20–23 single 10 mm dynamic-driver IEM in a translucent ruby-red PET shell (20 Ω, 113.5 dB, 0.78 mm 2-pin) whose low end was re-tuned bassier from community feedback, and which ships with a generous accessory bundle (HE Sonic and wide-bore Tang Sancai tips plus a matte-red cable). It is a distinct SKU from the base Wan'er S.G II 'Gen 2' (19 Ω, a 'balanced V-shape'), from the original 2023 Wan'er S.G, and from the Studio Edition.

TANGZU's Wan'er is one of the most-recommended names in ultra-budget audio — the original Wan'er S.G became a cult first-IEM, and its 2025 sequel, the Wan'er S.G II, kept the warm, vocal-forward house sound (though some felt the base 'Gen 2' retune stepped back from the original). The Bass Version (Lion Edition) — universally nicknamed the Red Lion for its translucent ruby shell — is a community-feedback-driven retune that lifts the low end, wrapped in an unusually generous accessory package for the money.

It arrives into the most crowded, cut-throat corner of the hobby: sub-$25 Chi-Fi, where it's compared to the 7Hz Zero:2, Truthear Gate, Moondrop Chu II and the hyped GK Kunten. Its reputation is a friendly, warm all-rounder and a phenomenal accessory value — most reviewers recommend it and Reddit sentiment runs positive. The disagreements are specific and worth mapping: whether a 'Bass Version' that reviewers keep calling 'controlled' actually delivers enough bass, whether the treble is smooth or a touch hot, and whether the shell is comfortably light or a bit bulky.

The overview

A ~$20–23 warm, vocal-forward single-dynamic-driver IEM — the bass-retuned 'Red Lion' edition of TANGZU's budget-favorite Wan'er S.G II. Reviewers broadly agree on the shape of it: a softened, warm take on Harman with a lifted low end and forward, clear vocals, sold with an accessory bundle (two good tip sets and a nice red cable) that's the single most-praised thing about it and anchors an emphatic value verdict. The low end is genuinely elevated over the base Wan'er 2 and impactful, but nearly everyone qualifies it as controlled rather than a true bass cannon — a few feel it doesn't dig especially deep. Three things split opinion. Treble divides: most hear it as smooth, easy and tamer than rivals, while a camp — often the treble-sensitive, or those using the brighter wide-bore tips — finds the upper mids and highs a touch hot or shouty, tracking the same 2–3 kHz lift that makes the vocals pop. Comfort divides: many find it light with a safe, universal, short-nozzle fit (small ears included), while others find the shell bulky or the nozzle large. And the near-universal knocks are two: an average-to-narrow soundstage with only okay separation, and a plasticky shell with scattered reports of channel imbalance or a driver failing within weeks. Positional imaging and footstep cues punch above the price for casual gaming, and at 20 Ω / 113.5 dB it's very easy to drive off a phone. For a beginner who wants a warm, forgiving set and a genuinely generous box for pocket change, it's easy to recommend — just not as a basshead or treble-head pick.

Where they agree

  • A warm, vocal-forward single 10 mm dynamic-driver tuning — a 'softened Harman' with lifted bass and forward, clear vocals.
  • A standout accessory bundle for the money (two good tip sets — HE Sonic and wide-bore Tang Sancai — plus a nice matte-red cable), which drives an emphatic value verdict.
  • Clear, present vocals are the strongest sonic trait; 'vocal and mid-range clarity' tops the community pros.
  • Noticeably more bass than the base Wan'er 2, impactful but controlled — reviewers repeatedly note it is not a basshead set.
  • Above-its-price positional imaging and footstep cues — a practical pick for casual FPS/gaming.
  • Very easy to drive at 20 Ω / 113.5 dB — runs loud and clean off a phone.

Where they split

  • How much bass a 'Bass Version' should deliver: a genuine, satisfying low-end lift vs. pleasant-but-modest and not the sub-bass cannon the name implies (a few feel it doesn't dig deep).
  • Treble: smooth, relaxed and tamer than rivals vs. a touch hot or shouty in the upper mids/highs — tracking the 2–3 kHz lift, the wide-bore tips, and listener treble sensitivity.
  • Comfort and fit: light, safe and universal (small ears included) vs. a shell and nozzle some find bulky.

By aspect — in detail

Tonality

Moderate · 5 src

A warm, vocal-forward take on Harman — reviewers describe a 'softened Harman' with extra body through the mid-bass and lower mids and a slightly relaxed top, landing as a warm, mild-V, fun-but-safe sound. It keeps the Wan'er house character (warm, voice-first) and simply pushes the low end up a little.

The Waner SG Red Lion Edition goes for a softened Harman-style tuning, with a bit more body through the mid-bass and lower mids, and a slightly more relaxed take on the upper mids and treble.

Prime Audio

The Red Lions on the other hand has a more "fun" V shaped sound, way more warm than the GATE.

wathkat, r/iems

The tonality of the Wan'er 2 is a balanced V-shape.

Sonic Sleuth, KeepHiFi (on the base Wan'er 2)
Measured

The squig FR (soundcheck39, averaged L+R relative to 1 kHz) shows a warm, bass-tilted balance: an elevated sub-bass shelf (~+8 to +10 dB at 30–60 Hz), a mild ~500 Hz lower-mid dip, and a strong ear-gain rise peaking around +8 dB near 2.5 kHz — consistent with the 'warm, vocal-forward, softened Harman' descriptions and with the retune's brief to add low-end body.

Bass

Moderate · 5 src

The whole point of the 'Bass Version': the low end is lifted noticeably over the base Wan'er 2, and most hear it as impactful and satisfying without bleeding into the mids. The consistent qualifier is that it's controlled rather than huge — reviewers repeatedly stress it is not a basshead set, and a few feel it doesn't extend especially deep. So: more bass than the base, well-judged, but not a sub-bass cannon despite the name.

The bass is well controlled. It's not overwhelming. I wouldn't consider these "basshead" levels of bass.

Jesse Sirivanchai (Linsoul verified owner)

It's not a sub-bass monster, but it doesn't feel lacking either, just a well-judged balance that supports the rest of the tuning.

Prime Audio

Overall sound is good, bass is impactful (but doesn't extend extremely low) and everything else kind of is just fine.

Ocram_s_Razor, r/iems
Measured

The measured sub-bass sits roughly +8 to +10 dB above the midrange (30–60 Hz vs 1 kHz on the squig graph) — a real, audible low-end lift, but it rolls in as a warm shelf rather than a towering sub-bass peak, matching the 'impactful but controlled' impressions. As with any dynamic driver, felt bass leans on a good tip seal.

Mids

Moderate · 5 src

The highlight. Vocals are pushed forward and read clear and present — both male body and female clarity get called out, and 'vocal and mid-range clarity' tops the community's list of pros. The one caveat is the flip side of that forwardness: the ~2–3 kHz lift can leave the upper mids sitting on the edge of shouty on hot tracks.

Vocals are where things stand out. Despite the warmer tilt, they come across quite forward, largely thanks to that 2–3kHz lift.

Prime Audio

Excellent vocal and mid-range clarity

The upper mids sit right on the edge of being shouty, but generally stop short of becoming fatiguing.

Prime Audio

Treble

Contested · 4 src

The most genuinely split axis. To most, the top end is smooth, easy and non-fatiguing — relaxed, with no real sibilance and 'tamer' than hyped rivals like the GK Kunten, though it trades away the last bit of sparkle and air. But a real camp — often treble-sensitive listeners, or those on the brighter wide-bore Tang Sancai tips — hears the upper mids and highs push too far forward, shouty or hot on some tracks. It tracks the 2–3 kHz lift and tip choice more than a bad unit.

Measured

The squig graph shows the ear-gain peak near 2.5 kHz (~+8 dB over 1 kHz) with a relatively moderate, un-spiky upper treble (no sharp sibilance peak in the 6–10 kHz region) — which is why most hear the top as smooth/tame, while the strong presence region is what the 'a bit too much' camp is reacting to.

⚠ vs. listeners — Both camps can be right on the same earphone: the 'smooth' read describes the relaxed upper treble, while the 'too much/shouty' read is the forward 2–3 kHz presence lift — amplified by the brighter wide-bore tips or a treble-sensitive listener.

Where it splits
Smooth, relaxed and non-fatiguing — safe and tamer than brighter rivals, if short on sparkle.55%

It is crisp and a touch airy, but keeps things smooth overall. There is enough presence to avoid sounding closed-in, but it does not push for sparkle or sharpness.

Prime Audio
A touch too much — the upper mids/highs come forward enough to read hot or shouty for some.45%

The Red Lion's highs are a bit too much, I'll probably play with eq to lower them

Soundstage

Moderate · 3 src

A common knock rather than a strength. Impressions cluster around average-to-narrow: reviewers call the stage about average and slightly intimate at best, and the community aggregate lists a narrow or congested stage with only okay separation among its top cons. Fine for the money, not a spacious set.

Soundstage is about average in size, leaning slightly intimate, but imaging is handled well enough to keep things organised.

Prime Audio

Narrow or congested soundstage and poor separation

Both have relatively poor sound stage lol.

Imaging

Moderate · 3 src

Punches above the price for positioning. Despite the modest stage, listeners consistently place footsteps and cues well, and it's specifically praised for casual FPS/gaming — one of its recurring practical strengths for a $20 set.

Great for gaming, especially FPS

loved it when it comes to the hearing footsteps.

Detail

Moderate · 3 src

Adequate for the money without being a technical set. The read is 'decent for the price' at best — one first-hand reviewer summed the non-vocal performance up as 'kind of just fine,' and more analytical listeners reach for detail-first rivals instead. Buy it for tone and value, not resolution.

these are good for the money, but you might find there's better or similar IEMs at that price point, so just temper your expectations and buy them for the right reasons.

Comfort

Contested · 4 src

Genuinely split. Many find it light with a safe, universal fit and short-ish nozzles that even small ears handle for hours — comfort makes the community's pro list. But 'bulky design and large nozzle cause fit issues' also makes its con list, and a few owners find the shell awkward. It's the same shell as the base Wan'er 2, so a tip swap and ear shape decide it.

Where it splits
Light and comfortable — a safe, universal fit that suits long sessions and even small ears.60%

also a very safe universal fit, even my small-eared gf can wear them with no issues

TokkenDev, r/iems
Bulky for some — the shell and large nozzle cause fit trouble.40%

Build

Moderate · 4 src

The soft spot. The translucent shell looks the part but feels plasticky and toy-like in hand, 'poor durability and cheap plastic build quality' is a top community con, and retail reviews include a real thread of QC failures — channel imbalance and a driver going soft or dead within weeks. The upside sits elsewhere: the included cable and tips genuinely feel a cut above the price.

Poor durability and cheap plastic build quality

The IEM's build looks and feel like a plastic toy.

Altrebelle, r/iems (via RedditRecs)

Originally they worked great but I've have these for barely 3 months and the volume is already much softer in the right ear than the left one.

Value

Strong consensus · 5 src

The least contested point, and the set's real headline: at around $20 it's near-universally called a great-value starter, and the accessory bundle — two good tip sets and a well-behaved matte-red cable — is singled out as one of the best unboxings at the price. Reviewers who are lukewarm on the sound still rate the package a steal.

At around $23, this is simply a banger.

Prime Audio

for that money, you'll have one of the best unboxing experiences considering how much you are getting out of the package.

Comprehensive and high-quality included accessories (including premium ear tips and cable)

RedditRecs (aggregated from 374 Reddit reviews)

Best for

  • Beginners and first-IEM buyers who want a warm, forgiving, easy-to-drive set for around $20
  • Vocal-forward listeners — pop, hip-hop, acoustic and vocal-centric music
  • Buyers who value the box: two good tip sets and a nice cable make it a strong accessory deal
  • Casual gamers who want clear footstep cues without spending more
  • People who wanted a bit more bass than the base Wan'er 2 but not a bloated basshead sound

Skip if

  • You want a true basshead / deep sub-bass cannon — this is lifted but controlled
  • You're treble-sensitive and won't tip-roll or EQ — the forward 2–3 kHz can read hot on some tracks and tips
  • You want a wide, spacious soundstage with sharp separation — it's average-to-intimate
  • You prioritize build and durability — the shell feels plasticky and there are scattered QC / channel-imbalance reports
  • You already own a good warm budget set (base Wan'er 2, Chu II, Zero:2) — the upgrade may be mostly the accessories
