How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a wired, audiophile-leaning in-ear monitor built around a detachable cable and a driver tuned for music detail, choose Herdslive Yongse; if you need true wireless freedom with touch controls and a pocket charging case for commuting, workouts and calls, choose iTouch Pulse Buds True.
These two aren't really rivals in the same race. One is a wired IEM aimed at people who care about cable upgrades and driver tuning. The other is a cable-free everyday earbud built for convenience. Your lifestyle picks the winner here, not a spec sheet.
• Herdslive Yongse — biggest strength: A 10mm dynamic driver with a PET diaphragm, a detachable 0.78mm flat 2-pin connector, and an upgraded silver-plated OFC cable that's designed for low signal loss and a more dynamic soundstage.
• Herdslive Yongse — biggest trade-off: It's wired, 3.5mm only, with no charging case and no wireless convenience — you're tethered to your source.
• iTouch Pulse Buds True — biggest strength: True wireless freedom via Bluetooth 5.4, touch controls, a USB-C charging case, and up to 12 hours of total playtime in a 4g-per-bud package.
• iTouch Pulse Buds True — biggest trade-off: Fixed drivers and a built-in battery you can't swap or upgrade; it's built for convenience, not for cable or tuning swaps.
• Who Herdslive Yongse is for: Music-first listeners and gamers who want a wired IEM they can upgrade and repair.
• Who iTouch Pulse Buds True is for: Commuters, gym-goers and call-takers who want to pop in and go.
The Yongse (sold under the TANGZU Wan'er II S.G name) is a wired in-ear monitor that leans hard into the enthusiast side of the hobby. Its headline feature is a 10mm dynamic driver with a PET diaphragm, paired with an upgraded driver chamber. The design intent, per the specs, is to keep the musicality of the original while sharpening clarity and top-end detail. Frequency range runs the standard 20Hz to 20,000Hz. If you like a balanced, immersive presentation rather than a bass-heavy thump, that tuning language points in your direction.
The part that separates it from most cheap earbuds is the hardware around the driver. It uses a 0.78mm flat 2-pin connector — a change from the older raised 2-pin design — which the spec sheet frames as a sturdier, more streamlined connection. Practically, that means the cable is detachable and replaceable. The included cable is a silver-plated oxygen-free copper (OFC) upgrade, engineered for conductivity and minimal signal loss. For a buyer, the takeaway is simple: this is a set you can maintain and tweak over time instead of throwing away when a wire frays.
Comfort and fit get real attention too, with a sculpted housing based on ear-anatomy research and patented eartips for noise isolation. It's plastic-bodied, white, with a 3.5mm jack, push-button control and a one-year manufacturer warranty. Buy it if you want a wired, upgradeable IEM for focused music listening or gaming at a desk. Skip it if you need wireless, a charging case, or freedom from a cable while you move.
The iTouch Pulse Buds True are the opposite philosophy: delete the wire, add convenience. They're true wireless earbuds using Bluetooth 5.4 for a stable connection up to roughly 33 feet (10 meters), with fast pairing and no companion app required. They work with iPhone, Android, tablets and any Bluetooth-enabled device — open the case, pair once, done. For anyone who's ever fought with a tangled cable on a train platform, that's the whole pitch.
The audio side is a 10mm dynamic driver with a 20Hz–20KHz frequency range, 16-ohm impedance and 85dB sensitivity — a spec set that suggests they're easy to drive and tuned for clear, balanced everyday sound rather than critical listening. Each bud weighs about 4g, which is the kind of number that matters when you're wearing them for a full commute. Touch controls on each earbud handle play/pause, track skipping, calls and voice-assistant activation, and there's a built-in mic for calls.
Battery is the headline convenience spec: about 3–5 hours per charge and up to 12 hours total with the case, recharging via USB-C in roughly 1.5 hours. The matte case is genuinely pocket-sized (about 5.5cm long). An IPX4 rating means sweat and splashes are fine, so gym sessions and runs are in scope. Buy it if you want grab-and-go wireless audio for commuting, workouts and calls. Skip it if you care about cable upgrades, detachable hardware, or squeezing maximum detail out of your music.
• Best for sound-quality-first listening → Herdslive Yongse. The PET-diaphragm driver, silver-plated OFC cable and detail-focused tuning are aimed squarely at music.
• Best for wireless freedom and commuting → iTouch Pulse Buds True. Bluetooth 5.4 and no cable means nothing to snag on a bag strap or jacket zip.
• Best for workouts and sweaty sessions → iTouch Pulse Buds True. The IPX4 splash-resistant build is designed for exactly that; the Yongse makes no such claim.
• Best for longevity and repairability → Herdslive Yongse. The detachable 0.78mm 2-pin cable means a worn wire is a swap, not a death sentence.
• Best for calls and voice assistants → iTouch Pulse Buds True. A built-in mic plus touch-activated Siri or Google Assistant beats a no-mic wired IEM for phone use.
• Best for gaming at a desk → Herdslive Yongse. Wired 3.5mm means no Bluetooth latency to think about, and the flat 2-pin connection stays put.
• Best for all-day battery convenience → iTouch Pulse Buds True. Up to 12 hours total with the case versus a cable that needs a powered source.
• Best for tinkerers and IEM collectors → Herdslive Yongse. The flat 2-pin connector is compatible with a range of other IEM cables, so you can experiment.
If I had to pick one, I'd buy the Herdslive Yongse. In my opinion, the detachable silver-plated OFC cable, the flat 2-pin connector and the PET-diaphragm driver give it more long-term value for someone who actually listens to music rather than just needs background audio. It's the set I'd reach for at my desk for music and gaming. That said, if your life happens on the move — gym, train, calls — I'd point you to the iTouch Pulse Buds True without hesitation, because no wired IEM can match that convenience. Match the tool to the job.
FAQ
The iTouch Pulse Buds True. Its IPX4 splash-resistant design and 4g-per-bud fit are built for sweat and movement, and there's no cable to catch on equipment. The Yongse is better suited to a stationary setup.
Yes. They pair over Bluetooth 5.4 with iPhone, Android phones, tablets and other Bluetooth devices, with no companion app required. Pairing is done once, then they reconnect.
That's subjective, but the design intent differs. The Yongse targets detail and a dynamic soundstage via its PET-diaphragm driver and upgraded cable, while the Pulse Buds True are tuned for clear, balanced everyday listening. For critical music listening I'd lean Yongse; for casual on-the-go audio the Pulse Buds are plenty.
