How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a wireless, sweat-resistant neckband you can wear through workouts and long commutes without hunting for a charger, choose WAVEFUN Neckband; if you need wired, audiophile-leaning in-ears with a detachable cable and real passive noise isolation for critical listening or gaming, choose Linsoul TANGZU Wan'er S.G.
• WAVEFUN Neckband — biggest strength: A flexible neckband body with Bluetooth 5.3, a 12-hour battery, and a 15-minute quick charge that yields about 4 hours of playback. It's built to stay on your neck and out of your way.
• WAVEFUN Neckband — biggest trade-off: No active noise cancellation, plastic build, and touch-based volume controls, so it's a convenience-first product rather than a sound-quality-first one.
• Linsoul TANGZU Wan'er S.G — biggest strength: A 10mm PET-diaphragm dynamic driver, 19-ohm impedance, 113.5dB sensitivity, and passive noise isolation in a wired, detachable-cable IEM.
• Linsoul TANGZU Wan'er S.G — biggest trade-off: It's wired. There's no battery, no Bluetooth, and no wireless freedom — you're tethered to your source at all times.
• Who each is for: Pick the WAVEFUN if movement, battery life and hands-free calling drive your day. Pick the TANGZU if you sit down to listen, game, or monitor and want isolation and cable flexibility.
The WAVEFUN Neckband is a lifestyle audio product first and a listening product second, and that's not a knock — it's a design brief. It uses Bluetooth 5.3 with a 10-meter range, so you can leave your phone on a bench or desk and keep moving. The neckband itself is flexible, which means it drapes rather than clamps, and the two earbuds are magnetic so they snap together when you pull them out of your ears. That single detail is why this thing works for the gym: you're not stuffing loose buds into a pocket between sets.
Battery is where it earns its place. The 12-hour average playback life means a full workday plus a commute, and the quick-charge claim is genuinely useful — roughly 15 minutes on the charger gets you around 4 hours of listening, with a full charge taking about 45 minutes. If you're the kind of person who remembers to charge things only when they're already dead, that ratio matters more than any spec sheet number.
On features, you get an ATS3015 processor, SBC and AAC codec support, and a 10mm dynamic driver tuned with an emphasis on bass. There's a Gaming Mode you trigger by holding volume up and down together for two seconds, which drops latency to a rated 45ms — fine for mobile games, YouTube, TikTok and live streams. There's also a Group Sound Mode where a triple-click on the power button syncs two units into a shared TWS pairing, so two people can listen to the same source. A single tap-and-hold on the power button fires up Siri or Google Assistant, and there's a built-in mic for hands-free calls.
Who should buy it: runners, gym-goers, cyclists, people who take a lot of calls on the move, and anyone who wants one pair of headphones that survives sweat (it's rated IPX5) and doesn't need babysitting. Who should skip it: if you care about detail retrieval, soundstage, or hearing the texture of a recording, this isn't the tool — the tuning leans bass-forward and there's no noise cancellation at all. Also skip it if you dislike touch controls; volume is handled by touch rather than physical buttons, and touch controls are polarizing.
The Wan'er S.G II is the opposite philosophy. It's a wired in-ear monitor with a 3.5mm jack, a 10mm dynamic driver using a PET diaphragm, and an upgraded driver chamber that TANGZU says reduces distortion and extends the top end compared to the first generation. The numbers tell you a lot about intent: 19-ohm impedance and 113.5dB sensitivity mean it's easy to drive. You don't need a dedicated amp — a phone dongle, a laptop jack, or a budget DAC will get it loud without strain.
The sound signature is described as balanced but more detailed than the original, keeping the smooth, full-bodied tonality while improving resolution. That's a meaningful distinction for a buyer: this is not a sterile, clinical monitor. It's tuned to be pleasant first and revealing second, which is exactly what you want if you're listening for enjoyment rather than mixing.
Fit and isolation are the other half of the story. The shell shape was reworked around ear-anatomy research for a more secure, comfortable fit over long sessions, and it ships with SANCAl eartips that seal well. Combined with passive noise cancellation, that seal is what actually blocks out a bus engine or an office HVAC hum — no battery required, no ANC processing, just a good physical fit.
The cable deserves its own paragraph. You get a 1.2m 5N OFC braided cable, and critically, it's detachable via a 0.78mm flat 2-pin connector. That flat connector is a change from the first generation's raised 2-pin, and it sits more flush and feels sturdier. It also means you can swap cables later — replace a worn one, go balanced, or switch to a mic cable if you need one. There's a Type-C with mic variant in the lineup for people who want calls handled without a dongle.
Side-by-Side: Which Should You Choose?
• Best for battery life → WAVEFUN Neckband. 12 hours of playback and a 15-minute charge that returns about 4 hours.
• Best for workouts and sweat → WAVEFUN Neckband. IPX5 sweat and splash resistance plus a magnetic, neck-worn design that won't fall out mid-run.
• Best for sound detail and resolution → Linsoul TANGZU Wan'er S.G. A PET-diaphragm dynamic driver with an upgraded chamber aimed at lower distortion and better top-end extension.
• Best for noise isolation → Linsoul TANGZU Wan'er S.G. Passive isolation from a proper seal with SANCAl eartips beats an open, ANC-free neckband every time.
• Best for gaming → Linsoul TANGZU Wan'er S.G if you want isolation and clarity; WAVEFUN Neckband if you need low latency wirelessly — it's rated at 45ms in Gaming Mode.
• Best for hands-free calls on the move → WAVEFUN Neckband. Built-in mic, Bluetooth 5.3, and voice-assistant activation from the power button.
• Best for cable flexibility and repairability → Linsoul TANGZU Wan'er S.G. The 0.78mm flat 2-pin detachable design lets you swap the 5N OFC cable.
• Best for sharing audio with someone next to you → WAVEFUN Neckband. Group Sound Mode syncs two units into one shared pairing.
If I had to pick one for myself, I'd take the Linsoul TANGZU Wan'er S.G. In my opinion, the wired design, the easy-to-drive 19-ohm/113.5dB spec, the passive isolation, and the detachable 0.78mm cable make it the better long-term purchase for anyone who actually sits and listens — and the swappable cable means it can outlive a worn connection in a way a sealed neckband can't. That said, I'd recommend the WAVEFUN Neckband without hesitation to the runner, the gym regular, or the person who lives on calls and hates charging. They're not competing for the same buyer; they're competing for the same pocket. Pick based on whether you're moving or sitting.
FAQ
No. At 19 ohms and 113.5dB sensitivity, it's easy to drive from a phone, laptop, or a simple USB-C dongle. A dedicated amp is optional, not required.
The Wan'er S.G, thanks to passive noise cancellation from a proper in-ear seal with the included SANCAl eartips. The WAVEFUN Neckband has no noise cancellation at all, so you'll hear traffic and gym noise.
