Most owners see the Tangzu Wan'er S.G as a standout budget pick, praising its fun, warm, bass-forward tuning for pop, hip-hop, and EDM, its light comfortable fit, and an eye-opening price-to-performance ratio that repeatedly earns 'no brainer' verdicts at $15-25. Many also recommend it as a first IEM, and some find the newer S.G/SG2 revisions tighter and more detailed than the original. A meaningful minority push back, though: durability complaints are common, with cables, connectors, or drivers failing anywhere from 6 to 17 months in, and a handful of owners find the bass boomy or muddy and the treble or vocals too forward for comfort. A smaller group also shrugs it off as overhyped, arguing it doesn't really stand out in the now-crowded sub-$20 IEM market.
Owners overwhelmingly praise the Truthear Zero:Red as an exceptional value pick, with dozens calling it the best IEM they've heard under $100 thanks to its balanced, natural, non-fatiguing tuning and punchy, well-extended bass that beats gaming headsets and pricier IEMs alike. Many say it works great straight out of a phone or dongle. However, a meaningful minority pushes back hard on the hype, finding it overrated and less technical than its reputation suggests, while the most common physical complaint by far is the wide nozzle causing ear discomfort or outright pain on longer sessions. A smaller group also dings the stock cable and earloop fit, and some find the tuning swings too bassy or too thin depending on taste.

Real owners lean toward the Waner S.G: 84% of 31 owners recommend it, vs 63% of 38 for the Zero Red.
Owners point the Waner S.G at budget beginners wanting a first IEM under $20 with warm, fun sound, and bass-leaning listeners into pop, EDM, and hip-hop.
Owners point the Zero Red at budget-conscious listeners wanting a natural, well-balanced tuning under $100, and gamers who want punchy bass and detail for FPS/console play off a dongle.
The most-cited downside of the Waner S.G is durability problems - connectors, cables, or drivers failing or breaking within 6-17 months. For the Zero Red, it's wide/large nozzle causes discomfort or pain, especially during longer listening sessions, and doesn't fit all ear shapes.
