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, ultra-light open-ear set that keeps you plugged into your surroundings while you fish, choose GZCRDZ Air Conduction Open; if you need a wireless, long-battery open-ear headset for fishing trips where charging isn't an option, choose Monster Open Ear AC322.
• GZCRDZ Air Conduction Open — biggest strength: a wired 3.5mm connection with a built-in noise-reduction mic and mute button, at just 18g, so there's no battery to manage and no pairing to fight with on the bank.
• GZCRDZ Air Conduction Open — biggest trade-off: it's wired, uses push-button inline controls instead of touch, and its IPX4 rating is the lighter of the two when it comes to rain and sweat.
• Monster Open Ear AC322 — biggest strength: Bluetooth 5.4 with 36 hours of battery life and an IPX5 waterproof rating, plus an adjustable ear hook that's built to stay put during movement.
• Monster Open Ear AC322 — biggest trade-off: it's wireless only, so it depends on a charged battery and a Bluetooth source, and its touch controls can be finicky with wet or gloved hands.
• Who each pick is for: GZCRDZ suits the angler who wants zero charging hassle and a hardwired, always-ready connection. Monster suits the angler who wants freedom from cables and all-day wireless playback.
The GZCRDZ Air Conduction Open is, at its core, a simplicity play. It's a 3.5mm wired open-ear headphone — no Bluetooth, no battery, no pairing screen. You plug it into a phone, a music player, or anything with a standard headphone jack, and it works. For a long day on the water, that's genuinely appealing: there's no "did I charge it last night" moment, and no low-battery beep halfway through the afternoon bite.
Its open-ear design is the other headline. The earpiece sits on the outer ear rather than sealing the canal, so you keep hearing what's around you — a car pulling up, a bell, a buddy calling from the next spot. For fishing specifically, that ambient awareness is the whole point of choosing an open design over a sealed one. It's also light at 18g, with ergonomic earhooks that the spec sheet describes as built for all-day comfort and stability, and an IPX4 rating that handles rain and sweat. The inline remote gives you push-button volume, playback and call control, and there's a mute button for the noise-reduction mic.
Who should buy it: the angler who already carries a device with a headphone jack, wants the lightest possible thing on their ears, and values never thinking about charging. It also fits runners, cyclists and anyone doing online classes or live work who needs to hear their own environment.
Monster Open Ear AC322: Who It's For
The Monster Open Ear AC322 goes the other direction: it's fully wireless, Bluetooth 5.4, and built around endurance. The headline number is 36 hours of battery life, which is the kind of figure that means you can head out for a multi-day trip without packing a charger and still not think about it. If your fishing involves long sessions, early starts, or camping near the water, that matters more than almost anything else on the spec sheet.
It's also the more weather-ready of the two on paper. IPX5 waterproofing is a step up from IPX4, so it shrugs off sweat and rain with more margin. The open-ear design keeps you aware of your surroundings just like the GZCRDZ, and Monster's own description emphasizes "Pure Monster Sound" with a dynamic driver and a 20Hz–20kHz frequency range — a conventional full-range spec rather than anything exotic. The adjustable ear hook is a real practical detail: it lets you dial in the fit for different ear sizes, which is exactly the kind of thing that stops a headset sliding off when you turn to cast or net a fish.
Controls are touch-based, which is cleaner than buttons when your hands are dry and free — and more annoying when they're wet, gloved, or busy holding a rod. There's no noise control here either, just like the GZCRDZ, so neither is an active noise-cancelling product; both rely on the open design to let sound in rather than filtering it out.
Who should buy it: the wireless-first angler who wants 36 hours between charges, a secure adjustable fit, and IPX5 confidence against the weather. Also a strong pick for workouts and daily wear.
Who should skip it: anyone who distrusts touch controls outdoors, and anyone who wants the guaranteed, no-battery, no-pairing reliability of a cable.
• Best for battery life → Monster Open Ear AC322. 36 hours versus a wired connection that never needs charging at all — but if you want wireless freedom, Monster is the only one of the two that offers it.
• Best for a zero-hassle, always-ready setup → GZCRDZ Air Conduction Open. No battery, no pairing, no charging case; plug in and go.
• Best for wet-weather confidence → Monster Open Ear AC322. IPX5 edges out the GZCRDZ's IPX4 when rain and sweat are a real factor.
• Best for the lightest possible feel → GZCRDZ Air Conduction Open. 18g, with earhooks designed for stability over long wear.
• Best for fit tuning → Monster Open Ear AC322. The adjustable ear angle is a concrete advantage for different ear shapes.
• Best for control style → depends on you. Push buttons on the GZCRDZ work reliably with wet or gloved hands; Monster's touch controls are slicker but fussier outdoors.
• Best for calling → GZCRDZ Air Conduction Open. A dedicated noise-reduction mic with a mute button gives you explicit call control.
• Best for device compatibility → GZCRDZ Air Conduction Open if you have a 3.5mm jack; Monster Open Ear AC322 if you'd rather stay wireless with Bluetooth 5.4.
For fishing, I'd buy the Monster Open Ear AC322. In my opinion, the combination of 36 hours of battery, Bluetooth 5.4, IPX5 waterproofing and an adjustable ear hook is simply the more practical package for a full day — or several days — on the water, and the wireless freedom is worth the trade-off of managing a charge. I'd only reach for the GZCRDZ Air Conduction Open instead if you specifically want a wired, never-charge, ultra-light setup and your device still has a headphone jack. Both keep you aware of your surroundings, which is the real reason to fish in open-ear audio at all. If you care about the current price, check it on Amazon before deciding.
FAQ
No. Neither the GZCRDZ Air Conduction Open nor the Monster Open Ear AC322 lists active noise cancellation — both spec sheets say noise control: None. Their open-ear design deliberately lets outside sound in, which is usually what anglers actually want.
In my opinion the Monster Open Ear AC322 fits most anglers better, mainly for the 36-hour battery, Bluetooth 5.4 and IPX5 rating. The GZCRDZ Air Conduction Open wins if you want a wired connection and no charging at all.
Only the Monster Open Ear AC322 uses touch controls. The GZCRDZ Air Conduction Open uses an inline push-button remote with volume and a mic mute. If you'd rather have physical buttons you can find by feel with wet hands, the GZCRDZ is the more forgiving choice.
Pick wired (GZCRDZ) if you want zero charging and your device has a 3.5mm jack. Pick wireless (Monster) if you want no cable snagging on gear or clothing and you value the 36-hour battery and IPX5 rating.
