If you want wired, driver-focused fidelity with a proper hybrid setup and a hi-res frequency ceiling of 40 kHz, choose FiiO FH3; if you need wireless freedom, adaptive noise cancellation and a massive 55-hour battery, choose QCY H3.
• FiiO FH3 — biggest strength: A three-driver hybrid (one 10mm beryllium-plated dynamic plus two Knowles balanced-armature drivers) with a physical + electronic three-way crossover, a silver-plated copper cable, and a 40 kHz top-end.
• FiiO FH3 — biggest trade-off: It's a wired in-ear with no Bluetooth at all, so every listen is tethered to a 3.5mm source.
• QCY H3 — biggest strength: Over-ear wireless with LDAC, Hi-Res Audio support, up to 50dB adaptive ANC and a 55-hour battery.
• QCY H3 — biggest trade-off: Its frequency response tops out at 20 kHz and it leans on Bluetooth rather than a dedicated DAC/amp chain.
• Who each pick is for: FiiO FH3 is for the wired listener chasing detail and bass; QCY H3 is for the commuter or traveler who wants quiet and long battery life.
The FH3 is a wired in-ear monitor built around a genuinely ambitious driver array. You get a 10mm beryllium-plated dynamic driver handling the low end, plus two Knowles balanced-armature drivers — an RAD-33518 for the treble and an ED-30262 for the mids. A physical and electronic three-way crossover splits the work, and FiiO's S.TURBO acoustic design uses longer turbine-style tubes to filter unwanted high frequencies so the bass hits deeper and harder. The stated frequency range runs to 40 kHz, impedance is 24 ohm, and sensitivity is 114 dB.
The build is worth noting too. The shell is aerospace-grade aluminum-magnesium alloy, machined on 5-axis CNC equipment to tight tolerances, and it's shaped as an around-the-ear hook for stability. FiiO includes an unusually generous kit: a 1.2m high-purity monocrystalline silver-plated copper cable (4 strands of 96 wires), 11 pairs of ear tips across 4 types, one soft and one solid carry case, and an eartip brush. The whole thing weighs just 7g, so it disappears in your ears.
In my opinion, this is the pick for someone who already owns a decent phone, tablet or PC and wants to hear the mid and high detail the FH3's Knowles drivers are designed to deliver. It suits quiet listening, at-home sessions and anyone who values a replaceable, upgradeable cable over wireless convenience. Skip it if you want to move around untethered, take calls on the go, or block out a noisy train — there's no Bluetooth here.
The QCY H3 (sold here as the H3 PRO) is the opposite philosophy: an over-ear wireless headphone designed to solve real-world problems. Its headline feature is up to 50dB of adaptive active noise cancellation, which auto-calibrates to your surroundings — useful on a busy station platform or a loud street. It supports LDAC and Hi-Res Audio over Bluetooth 5.4, driven by 40mm magnetic titanium-plated diaphragm drivers, with impedance at 32 ohm, sensitivity at 102 dB and a frequency range of 20 Hz to 20,000 Hz.
The practical stuff is strong. Battery life is rated at 55 hours, and a 10-minute quick charge gives 5 hours of playback — genuinely handy before a flight. There's a 360° spatial sound mode, a game mode with latency as low as 0.06s, and a custom EQ you can tune through the app. Controls are physical buttons plus app control, and the earcups are finished in leather and plastic. A 3.5mm audio cable is included, so you can run it wired if the battery runs out.
I'd recommend the H3 for commuters, frequent flyers, remote workers and anyone who wants one pair for the whole day without charging. Skip it if your priority is squeezing maximum mid and treble detail out of a wired source — the 20 kHz ceiling and Bluetooth transmission are the trade-offs you're accepting for convenience.
• Best for hi-res wired listening → FiiO FH3 (40 kHz frequency range, dedicated hybrid drivers, silver-plated copper cable).
• Best for wireless hi-res → QCY H3 (LDAC and Hi-Res Audio over Bluetooth 5.4).
• Best for noise cancellation → QCY H3 (up to 50dB adaptive ANC).
• Best for battery life → QCY H3 (55 hours, plus a 10-minute charge for 5 hours).
• Best for bass depth and driver count → FiiO FH3 (10mm beryllium dynamic + 2 Knowles BA, S.TURBO design).
• Best for long listening sessions away from a charger → QCY H3; best for critical, tethered listening → FiiO FH3.
• Best for low-latency gaming and movies → QCY H3 (0.06s game mode, spatial sound).
• Best for a lightweight, stable in-ear fit → FiiO FH3 (7g, around-the-ear hook, 11 pairs of tips included).
If I had to pick one for myself, I'd take the FiiO FH3. Its three-driver hybrid setup, three-way crossover and 40 kHz top-end are exactly what "hi-res" means to me when I'm sitting down to actually listen — and the included cable and tip selection make it a complete wired package. The QCY H3 is the smarter daily driver for most people, though: LDAC, 50dB ANC and 55 hours of battery cover commuting, travel and work in a way a wired in-ear simply can't. Buy the FH3 for fidelity; buy the H3 for freedom.
what is hi res headphones
Hi-res headphones are headphones designed to reproduce audio with greater detail and a wider frequency range than standard playback. In practice, that means support for high-resolution formats and, often, an extended frequency response — like the FiiO FH3's 40 kHz range or the QCY H3's Hi-Res Audio and LDAC support.
what is hi res audio headphones
Hi-res audio refers to audio that carries more detail than a standard compressed stream. Headphones marketed as hi-res audio are built to resolve that extra detail — the QCY H3, for example, supports LDAC and Hi-Res Audio, while the FH3 uses dedicated Knowles balanced-armature drivers to keep mids and treble clean.
what are hi res headphones
They're headphones built for higher-resolution sound, usually identified by extended frequency response, support for hi-res codecs, or high-quality driver designs. The FH3 qualifies through its hybrid driver array and 40 kHz ceiling; the H3 qualifies through LDAC and Hi-Res Audio certification over Bluetooth.
which headphones support hi res lossless
Hi-res lossless generally needs a wired connection to a capable source, which is where the FiiO FH3's 3.5mm wired design and silver-plated copper cable come in. The QCY H3 supports LDAC for high-quality wireless audio and also includes a 3.5mm cable, so it can run wired when you want that path.
