What Waner S.G owners think

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.

What Letshuoer S12 Pro owners say

“The S12 is brighter than the HeyDay (to my ears), so I would recommend a warmer amp source to really make them shine, and I would assume that they would pair great with tube amps”
— GlenAppleton on Head-Fi
“I just love my S12 PRO.”
— @fhreire on YouTube
“The bass on most planars including the S12PRO decays quickly. Gives the entire sound profile a lighter note weight and no amount of tip rolling will change that aspect (I went through 12 pairs).”
— StolenServiceAnimal on Reddit
