An $18 single-dynamic-driver IEM that twenty-five measurement rigs agree is a mild, vocal-forward take on Harman: a moderate sub-bass shelf, an ear-gain peak at 2–2.5 kHz, a dip from 3 to 7 kHz, and more upper treble than the target. Against the original Wan'er on the same rigs it is almost the same earphone — bass and mids within about 1 dB — with 2–5 dB more energy above 10 kHz. Sources broadly agree that the accessories carry the value: the Sancai tips and the cable are worth much of the price, imaging is good for the money, and the soundstage is about average. Bass is the mildest complaint — clean and controlled, but most find it lighter than the original and nobody calls it a basshead set. The real arguments are about the top half. Treble splits between smooth and inoffensive and bright, sharp or harsh; the vocals split between clear and forward and shouty; and the overall tuning splits between a balanced all-rounder and a brighter step back from the first Wan'er. Comfort divides on ear size — light and ergonomic for some, a large shell with a short nozzle that will not seal for others — and build divides between a real upgrade and a tail of fragile shells, quiet channels and failing Type-C cables, which measure as a brighter tuning too. A strong starter package, then, whose sound now has as many sceptics as fans.
About this product
The standard second-generation Wan'er S.G (2025): an $18 single 10 mm PET dynamic-driver IEM (19 Ω, flat 0.78 mm 2-pin socket) in white, black or blue, sold with a 3.5 mm, 4.4 mm, 3.5 mm-with-mic or Type-C-with-mic cable and bundled with Tang Sancai Balanced tips. Not the 2023 original Wan'er S.G, not the Bass Version (Lion Edition, the 'Red Lion', covered separately), and not the Headphone Zone x TANGZU edition; the Jade Dragon and Amethyst Dragon colourways share this tuning.
TANGZU's original Wan'er S.G was the hobby's standard 'first IEM' answer for two years: a warm, vocal-forward single dynamic driver for about $20. The Wan'er S.G II arrived in March 2025 as the refresh — a redesigned shell, a flush 2-pin socket in place of the old raised one, a nicer silver-plated cable and, the headline for many buyers, a full set of TANGZU's own Tang Sancai tips in the box, at the same price.
It sits in the most crowded corner of the market, against the 7Hz Zero:2, Moondrop Chu II, Truthear Gate and GK Kunten. What follows is a read of some fifty sources — twenty-five measurement rigs, the Head-Fi and YouTube reviewers, Reddit, and about a thousand verified-buyer reviews — on what the update actually changed, and whether it is still the safe recommendation its predecessor was.
