If you want wired in-ear monitors that isolate sound through fit and housing while delivering detailed music and low-latency gaming audio, choose YINYOO KZ ZSN Pro; if you need over-ear earmuffs built to knock loud machinery and gunfire down to a safe level, choose Floriogra 2.
• YINYOO KZ ZSN Pro — biggest strength: a hybrid 1BA + 1DD driver setup with a 10 mm dynamic driver, deep bass and a wide soundstage, plus a removable cable that extends the life of the set.
• YINYOO KZ ZSN Pro — biggest trade-off: it is a wired, in-ear design with no mic on this version, so it depends on a 3.5 mm jack and on getting a good ear-tip seal for its sound isolation to work.
• Floriogra 2 — biggest strength: certified passive attenuation rated at SNR 34dB (ANSI S3.19), with double-layer dampening foam and a composite housing that seals around the ear.
• Floriogra 2 — biggest trade-off: it is purely protective gear — no audio playback, no cable, no drivers — and it is bulkier to carry than a pocket-sized IEM.
• Who each pick is for: YINYOO KZ ZSN Pro is for listeners, gamers, musicians and callers who want sound quality first; Floriogra 2 is for shooters, mowers, woodworkers and anyone who needs their environment turned down.
The KZ ZSN Pro is, at heart, a music and monitoring tool. YINYOO builds it around a hybrid driver layout — one balanced armature plus a 10 mm dynamic driver — and the spec sheet backs that up with a 20 Hz to 40 kHz frequency range, 25 ohm impedance and 104 dB sensitivity. In practice that combination is easy to drive from a phone or a laptop's headphone jack, and the tuning is described as balanced top to bottom with solid low end, clear mids and bright highs. If you want bass you can feel on a commute or in a game, this is the design that delivers it.
Build-wise, the shell mixes a zinc alloy cover with an imported resin cavity and an aluminum alloy vocal cavity, which is a deliberate choice: metal for rigidity and a premium feel, resin for a lighter, more comfortable in-ear fit. The cable is removable and uses a slot-protection design around the pins, so if the cable eventually fails you replace the cable rather than the whole earphone — a genuinely useful long-term feature, and YINYOO sells compatible cables separately. The 3.5 mm wired connection also means zero wireless latency, which is exactly why it shows up in gaming, stage, church worship, studio and band contexts.
Now the honest part. This specific version ships without a microphone, so it is not the pick for hands-free calls or voice chat unless you pair it with a separate mic. It is also wired — there is no Bluetooth here — and it relies on ear-tip fit for its sound isolation, which is listed simply as "Sound Isolation" rather than as a measured attenuation figure. That means how much outside noise it blocks depends heavily on how well the tips seal in your ears. Buy it if you want an affordable-feeling, well-built IEM for music, monitoring and low-latency gaming. Skip it if you need certified hearing protection, wireless freedom or a built-in mic.
The Floriogra 2 is a different category of product entirely, and it is worth being blunt about that: these are hearing protection earmuffs, not headphones you listen to music on. The core claim is measurable — SNR 34dB attenuation, certified to ANSI S3.19 (US) and CE EN 352-1 — achieved with double-layer sound-dampening foam inside a composite housing. For shooting, that rating is the whole point: it takes an impulse loud enough to damage hearing and brings it down to something survivable. The same logic applies to lawn mowers, chainsaws, factory floors, welding stations and heavy machinery.
Comfort and fit get real attention here too. The headband uses retractable steel wires so you can slide the cups to size, and the cups rotate a full 360° on their pins to follow the shape of your head. Inside, the ear cups are deliberately roomy, which keeps air moving and stops the clammy feeling you get from tight closed cups, while the skin-friendly imitation leather and high-density sponge create the acoustic seal that makes the attenuation work. A small hole at the bottom of the cup lets the sponge rebound slowly so it settles onto your head instead of fighting it.
It is also built to travel. The whole thing folds compactly and drops into a range bag or backpack, and Floriogra includes a carrying bag to keep dust off it. You get two pairs in the pack, which matters if you keep one set at home and one in a vehicle or range kit. The trade-offs are straightforward: it is not audio equipment, it is not wireless despite the "Active Noise Cancellation" label in the control field, and at 500 g it is something you notice on your head over a long session. Buy it if loud, harmful noise is the problem. Skip it if you actually want to hear music, calls or game audio.
• Best for audio quality → YINYOO KZ ZSN Pro. Hybrid 1BA + 1DD drivers, 20 Hz–40 kHz range, deep bass and a wide soundstage.
• Best for blocking dangerous noise → Floriogra 2. SNR 34dB certified attenuation to ANSI S3.19 and CE EN 352-1.
• Best for gaming and stage work → YINYOO KZ ZSN Pro. Wired 3.5 mm means zero-latency, and it is explicitly aimed at gaming, studio and worship-team use.
• Best for shooting, mowing and construction → Floriogra 2. These are the exact environments its certification covers.
• Best for long-term repairability → YINYOO KZ ZSN Pro. The removable cable with slot-protected pins can be swapped instead of replacing the earphones.
• Best for sharing or keeping a spare set → Floriogra 2. It comes as a 2 pack with a storage bag.
• Best for commuting and casual music → YINYOO KZ ZSN Pro, but note the isolation is fit-dependent, not certified.
• Best for all-day wear in a noisy workplace → Floriogra 2, thanks to the roomy cups, 360° rotating pins and slow-rebound foam padding.
In my opinion these two barely compete — they solve opposite problems. If your goal is to hear your music, your game or your instrument clearly and you can live with a wire, I would buy the YINYOO KZ ZSN Pro; the hybrid driver setup, the metal-and-resin build and the replaceable cable give you the most genuine audio value of the two. If your goal is to protect your hearing from a genuinely loud environment, I would buy the Floriogra 2 without hesitation, because a certified SNR 34dB rating is the only thing on this page that is actually a safety specification. Whichever way you lean, check the current price on Amazon before you commit — the numbers move, and that button is the only place worth trusting for it.
Passive noise cancelling headphones reduce noise physically rather than electronically — through materials and fit. The Floriogra 2 does this with double-layer sound-dampening foam and a composite housing that seals around the ear, rated at SNR 34dB.
They block sound by absorbing it and by preventing it from reaching your ear in the first place. A tight acoustic seal plus dense foam padding, like the high-density sponge and imitation leather on the Floriogra 2, does the work — no battery or electronics involved.
It means the reduction comes from the build, not from active circuitry. The YINYOO KZ ZSN Pro is the in-ear version of this idea: it lists "Sound Isolation" as its noise control, achieved by the eartip sealing your ear canal rather than by any powered system.
Anything where loud, sustained or impulsive noise is the problem — shooting, construction, mowing, woodworking or factory work, which is exactly what the Floriogra 2's ANSI S3.19 and CE EN 352-1 certifications are designed around. For music, gaming and monitoring instead, the YINYOO KZ ZSN Pro is the better fit.
