• QCY H3S biggest strength: hybrid active noise cancellation rated up to 56dB, a dual-driver setup with Hi-Res Audio and LDAC, and a claimed 102 hours of playtime — a genuine "shut the world out" headphone.
• QCY H3S biggest trade-off: it's a 244 g over-ear design that physically covers your ears, so you're sealed off from your environment and carrying more bulk.
• Gelecek Bone Conduction Open-Ear biggest strength: an open-ear, 29 g titanium frame that leaves your ear canals free so you stay aware of what's around you, with an IP55 rating for sweat and weather.
• Gelecek Bone Conduction Open-Ear biggest trade-off: roughly 10 hours of battery and no active noise cancellation — this is a sports-first headphone, not a quiet-cabin companion.
• Who each pick is for: QCY H3S for commuters, office workers and long-haul listeners who want immersion; Gelecek for runners, cyclists, gym-goers and anyone who refuses to block out the world.
The H3S is built around one idea: remove the noise and keep the music going. Its hybrid ANC is rated to cut ambient sound by up to 56dB, which is the kind of figure that matters on a train platform, a plane cabin or a shared office where chatter and hum never stop. If your listening happens in loud places, that single feature reframes the whole experience.
The audio side is unusually deliberate for this class. QCY pairs a 40mm mid-bass driver with a separate 13mm tweeter and describes it as a true physical crossover, so bass and treble are handed to different drivers instead of one doing everything. Add Hi-Res Audio and LDAC decoding, a 20Hz–40kHz frequency range and 40-ohm impedance, and you have a headphone aimed at people who care about detail, not just volume. The 360° spatial sound mode and a 60ms latency figure also make it plausible for video and casual gaming, where lag is the usual dealbreaker.
Buy it if you want maximum quiet, maximum runtime and wired-or-wireless Hi-Res listening in one package. Skip it if you need to hear traffic, colleagues or your surroundings, or you want something you can forget you're wearing during a sweaty workout — at 244 g with sealed earcups, this is a sit-down, focus-time headphone.
Gelecek Bone Conduction Open-Ear: Who It's For
The Gelecek takes the opposite approach entirely. Instead of sealing your ears, it sits on your cheekbones and sends sound through bone conduction, leaving your ear canals completely open. That's the whole point: you hear your music and the world at the same time. For runners on roads, cyclists in traffic or gym-goers who need to catch a coach's instruction, that awareness is a safety feature, and Gelecek leans into it directly.
The build supports the use case. A titanium frame weighing just 29 g is designed to flex and bend without deforming, so it survives being stuffed in a bag or bounced around during a workout. The hook-style open-ear fit avoids the pressure and heat of earcups, and an IP55 rating covers sweat, splashes and light rain — running, hiking and cycling are explicitly the target here.
On audio, Gelecek claims a fully enclosed cavity design that cuts sound leakage by up to 50%, which addresses the usual complaint about bone conduction: everyone around you hearing your playlist. Battery life is listed at up to 10 hours with Type-C charging, enough for a long training block, a commute and a workday of calls. There's a microphone with noise cancellation for hands-free calls and video meetings, and Bluetooth connectivity for wireless playback. It's a single-purpose tool, and it's honest about that.
Buy it if your priority is staying aware, staying light and staying sweat-proof during movement. Skip it if you want deep bass, isolation from noise, or marathon battery life — with no ANC and around 10 hours of runtime, it simply isn't designed for that.
Side-by-Side: Which Should You Choose?
• Best for noise cancellation → QCY H3S. Up to 56dB hybrid ANC versus none on the Gelecek.
• Best for staying aware of your surroundings → Gelecek. Open-ear bone conduction is the entire design premise.
• Best for running, cycling and gym work → Gelecek. 29 g titanium frame and IP55 sweat/water resistance.
• Best for sound quality and detail → QCY H3S. Dual drivers, Hi-Res Audio, LDAC and a 20Hz–40kHz range.
• Best for calls and multitasking → QCY H3S. Seven mics and multipoint across two devices.
• Best for all-day wear comfort → Gelecek. 29 g open-ear hooks beat 244 g sealed earcups for long sessions.
• Best for travel and storage → QCY H3S. It folds flat and swivels for compact packing.
If I could only pick one, I'd take the QCY H3S. In my opinion, it covers far more of real life — commuting, working, flights, calls, gaming, long stretches without a charger — and the dual-driver Hi-Res setup with LDAC gives it a sound-quality ceiling the Gelecek isn't chasing. The 102-hour claim and 56dB ANC are the kind of headlining features that hold up across dozens of everyday scenarios.
That said, I'd recommend the Gelecek without hesitation to anyone whose listening happens while moving outdoors. If you run or ride near traffic, open-ear awareness isn't a nice extra — it's the reason to buy. Check the current price on Amazon for both before you commit, since pricing moves and the gap between them is what usually decides these two.
FAQ
For commuting, yes — in my opinion. The H3S's up to 56dB hybrid ANC and 102-hour battery are built for noisy, long journeys, while the Gelecek leaves your ears open and offers around 10 hours, which suits movement more than a packed train.
It depends on the setting. The Gelecek is far lighter at 29 g with an open-ear hook fit, so it disappears during workouts. The H3S uses protein-leather earcups and an adjustable headband for cushioned, all-day over-ear comfort — just with more weight at 244 g.
You can wear it for light activity, but it has no water-resistance rating listed, and sealed 244 g earcups trap heat. For running, cycling or sweaty gym sessions, the Gelecek's IP55 rating and 29 g frame make it the more sensible pick.
