If you want serious noise cancelling and marathon battery life for long, focused listening, choose QCY H3S; if you need open-ear awareness, a secure sport fit and sweat resistance for running and cycling, choose TECKNET Open Ear Headphones. That's the whole decision in one line. Everything below is the reasoning behind it.
• QCY H3S biggest strength: Hybrid active noise cancelling rated to cut ambient noise by up to 56dB, plus a claimed 102 hours of playtime and Hi-Res Audio with LDAC and a dual-driver setup.
• QCY H3S biggest trade-off: It's an over-ear, closed-back design at around 244g — you're sealed off from the world, and you have to carry a full headband around.
• TECKNET Open Ear Headphones biggest strength: An open-ear hook design at roughly 8g per earbud that keeps your ear canal open, so you still hear traffic and conversations while you train, with IPX5 sweat and light-rain resistance.
• TECKNET Open Ear Headphones biggest trade-off: No noise cancelling at all, and the open structure means bass and isolation simply can't match a sealed over-ear pair.
• Who QCY H3S is for: commuters, office workers, frequent flyers and anyone who wants to disappear into their audio for weeks at a time.
• Who TECKNET Open Ear Headphones is for: runners, cyclists, gym-goers and outdoor workers who need music without losing situational awareness.
The QCY H3S is built around one idea: block the world out and keep going for as long as possible. The hybrid ANC system is rated to reduce ambient noise by up to 56dB, which is a serious figure for a headphone in this class. On a train, in a shared office, or on a plane, that's the difference between hearing your podcast and hearing everyone else's. Add the dual-driver arrangement — a 40mm mid-bass driver plus a dedicated 13mm tweeter with a physical crossover — and you get a sound design that separates the low end from the highs instead of smearing them together. Hi-Res Audio and LDAC support matter here too: LDAC carries far more data over Bluetooth than standard codecs, so if you stream from a compatible Android phone or a good music service, the H3S has the headroom to show it.
Then there's the battery. QCY claims 102 hours of playtime on a single charge, which is genuinely absurd in the best way — that's weeks of normal commuting between charges. And when you do run low, a 10-minute Type-C top-up is rated to give you 7 hours back. For anyone who has ever packed for a trip and realised their headphones were dead, that combination is the real selling point.
Who should buy it: commuters, remote workers, students, travellers and long-session listeners who value silence, battery and sound detail above all else. Who should skip it: anyone who needs to hear their surroundings for safety, and anyone who dislikes the feel of a sealed over-ear headphone. There's no headphone jack here, so wired-only setups are out too.
TECKNET Open Ear Headphones: Who It's For
The TECKNET Open Ear Headphones solve a completely different problem. Instead of sealing you off, they sit outside your ear canal on flexible hooks, weighing around 8g per earbud. The result is that music plays while traffic, conversation and announcements still come through. If you run or cycle on public roads, that's not a nice-to-have — it's the entire reason to buy them. It's also why they're comfortable for hours at a time: nothing is jammed into your ear, nothing builds up heat, and there's no pressure point to complain about after a long workday.
The sport side is handled properly. Soft, flexible ear hooks are designed to hold the buds in place during gym sessions, jogs, hikes and outdoor work, and IPX5 waterproofing resists sweat and light rain. That's exactly the kind of everyday abuse an open-ear pair gets, and it's the spec I'd check first if you train outdoors.
On audio, TECKNET uses large 14.2mm dynamic drivers, tuned for rich bass, balanced mids and crisp highs — sensible for music, podcasts, audiobooks and calls. Bluetooth 6.0 gives fast pairing and a stable 10-metre connection to phones, tablets and laptops, with low-latency audio for video. Battery is rated at up to 10 hours per charge and up to 40 hours total using the charging case's three extra full charges, and the smart LED display on the case shows remaining power at a glance. A 10-minute charge is rated for up to 2 hours of playback, wireless charging is supported, and touch controls handle play, calls and your voice assistant. TECKNET backs it with a 36-month warranty.
Who should buy it: runners, cyclists, gym-goers, walkers, delivery and outdoor workers, and anyone who wants background audio without blocking the world out. Who should skip it: anyone chasing maximum noise cancelling or deep, sealed-in bass.
Side-by-Side: Which Should You Choose?
• Best for noise cancelling → QCY H3S. Up to 56dB hybrid ANC versus no noise cancelling at all on the TECKNET.
• Best for battery life → QCY H3S. 102 hours per charge against roughly 10 hours per charge and 40 hours with the case.
• Best for running, cycling and gym use → TECKNET Open Ear Headphones. The ear-hook fit and IPX5 rating are made for sweat and movement.
• Best for staying aware of traffic and surroundings → TECKNET Open Ear Headphones. The open-ear structure is the whole point.
• Best for sound detail and hi-res listening → QCY H3S. Dual drivers, a physical crossover, Hi-Res Audio and LDAC support.
• Best for calls in noisy places → QCY H3S. Seven microphones, six with active noise cancellation.
• Best for long wear without ear fatigue → TECKNET Open Ear Headphones. Around 8g per earbud and nothing inside your ear canal.
• Best for travel and storage → QCY H3S. It swivels and folds flat, and multi-point keeps a laptop and phone connected at once.
My Verdict
For sound isolation and battery, yes — the QCY H3S has up to 56dB hybrid ANC, dual drivers with LDAC, and 102 hours of playtime. For open-ear awareness and sport use, the TECKNET is the better fit. They're built for different jobs.
No. The data sheet lists noise control as none, and the open-ear design doesn't seal the ear canal, so outside sound comes through by design. That's what makes them safer for running and cycling.
QCY rates the H3S at up to 102 hours per charge, with 7 hours from a 10-minute top-up. TECKNET rates roughly 7 hours of average battery life, up to 10 hours per charge and up to 40 hours total with the charging case.
Both support Bluetooth 6.0 and hands-free calling. The QCY H3S adds multi-point so you can stay connected to two devices at once, and its seven-microphone array is aimed at clearer calls in noisy environments.
