That one split explains almost every difference between these two. The GZCRDZ X7s is built around water — IPX8, bone conduction, a 32GB MP3 player so you can leave your phone on the pool deck. The Conyat X7 is built around weight and comfort — roughly 6.7g per earpiece, an open-ear hook design, and IPX7 protection. They overlap in the "sweat and rain" zone and diverge hard everywhere else, so let's map it out.
• GZCRDZ IPX8 — biggest strength: IPX8 waterproofing plus a built-in 32GB MP3 player, so it works with no phone at all while you swim.
• GZCRDZ IPX8 — biggest trade-off: Around 30–32g of total weight, a behind-the-head band, and a magnetic charging port that needs rinsing and drying after every session.
• Conyat Open-Ear Headphones — biggest strength: Roughly 6.7g per earpiece with ear hooks that leave your ear canal open — genuinely easy to forget you're wearing them.
• Conyat Open-Ear Headphones — biggest trade-off: IPX7, not IPX8, and no built-in music storage — it's a Bluetooth-only earbud, so it needs a paired device.
• Who each is for: GZCRDZ IPX8 → swimmers and heavy-sweat athletes who want music without a phone. Conyat Open-Ear → runners, gym-goers and commuters who want the lightest possible fit and full awareness of their surroundings.
The GZCRDZ X7s is, first and last, a swimming headphone. IPX8 is the highest water-resistance rating in this comparison, and the bone conduction driver sends sound through your cheekbones instead of into your ear canal — which is exactly what you want underwater, where normal earbuds either fall out or muffle everything. There are no ear tips to lose, no seal to break.
The honest trade-offs: it's a band-style design at roughly 30–32g, so it's noticeably more "equipment" than a tiny earbud, and the magnetic charging contacts are the known weak point — the manufacturer explicitly says to rinse with fresh water and dry them after use, and not to leave them soaking in salt water. Bone conduction also means less bass thump than a sealed earbud; the spec sheet claims a 20Hz–20KHz range, but physics is physics.
Buy it if you swim, surf, row, or sweat hard and want music with no phone nearby. Skip it if you want something invisible for the office, or you can't be bothered drying a charging port after every workout. It's backed by a 1-year warranty.
Conyat Open-Ear Headphones: Who It's For
The Conyat X7 goes the opposite direction: it's designed to disappear on your head. Each earpiece weighs roughly 6.7g, and the ergonomic ear-hook shape sits around your ear while leaving the ear canal completely open. That open design is the whole point — you hear traffic, your running buddy, the gym announcement, and your podcast at the same time, and there's no pressure building up inside your ear over a long day. The manufacturer positions it for sports, running, commuting and daily use, which is a fair read of the design.
It's IPX7 rated, so rain, sweat and a splash at the sink are fine. The spec sheet lists an ENC mic for calls, so voice pickup during a run is part of the design intent. Connectivity is Bluetooth with no 3.5mm jack, and it ships with a 2-year warranty — double the coverage of the GZCRDZ.
What you give up: there's no built-in memory, so it's useless without a paired phone or watch. There's no active noise cancellation (noise control is listed as "None"), which is consistent with an open-ear design — you're buying awareness, not isolation. And IPX7 is one step below IPX8, which in practice means it handles rain and sweat but isn't intended for swimming or submersion.
Side-by-Side: Which Should You Choose?
• Best for swimming → GZCRDZ IPX8. IPX8 and bone conduction are the only combination here that makes sense in a pool.
• Best for phone-free workouts → GZCRDZ IPX8. 32GB of internal storage means no device required.
• Best for long-wear comfort → Conyat Open-Ear Headphones. ~6.7g per earpiece versus a ~30–32g band.
• Best for running and cycling awareness → Conyat Open-Ear Headphones. Open ear canal, no passive isolation.
• Best for battery spec → GZCRDZ IPX8 on paper: 10 hours of music, 10 hours talk, 300 hours standby.
• Best for calls → Conyat Open-Ear Headphones if you value an ENC mic; the GZCRDZ also has a mic but is tuned for swimming first.
• Best for warranty → Conyat Open-Ear Headphones with 2 years versus GZCRDZ's 1 year.
• Best for low-maintenance ownership → Conyat Open-Ear Headphones. No magnetic charging contacts to rinse and dry after every session.
• Best for heavy sweat and rain only → either. Both handle it; IPX7 already covers that ground.
In my opinion, most people reading a comparison with "IPX8" in it are swimmers, and for them the GZCRDZ IPX8 is the only real answer here — the 32GB MP3 mode alone removes the phone problem that ruins every pool workout. I'd pick the Conyat Open-Ear Headphones only if swimming isn't on your list and comfort is: at roughly 6.7g per earpiece with a 2-year warranty, it's the easier pair to live with every single day. Decide which of those two lives you actually have, and the choice makes itself. Either way, check the current price on Amazon before committing, since both sit in budget-friendly territory.
are headphones waterproof
Most aren't — they're water resistant to varying degrees. Of these two, the GZCRDZ IPX8 carries the higher IPX8 rating, which is the level intended for continuous submersion, while the Conyat Open-Ear Headphones are IPX7, which covers sweat, rain and brief splashes but isn't meant for swimming. Always match the rating to the activity.
are headphones water resistant
Yes, many are, and both products here qualify. IPX7 (Conyat) handles sweat, rain and accidental splashes. IPX8 (GZCRDZ) goes further and is rated for immersion, which is why the manufacturer markets it as a swimming headphone. The GZCRDZ does carry one caveat: rinse and dry the magnetic charging contacts after use, and don't leave it in salt water.
IPX7 means the device survives being submerged in water for a limited time and depth; IPX8 means it's rated for deeper or longer immersion. In practice, IPX7 is your rain-and-sweat rating and IPX8 is your swimming rating. That's the single biggest functional gap between these two products.
Only for the Conyat. It's Bluetooth-only with no built-in storage. The GZCRDZ IPX8 works either way — Bluetooth 5.3 mode with a phone, or MP3 mode using its 32GB of internal memory, which is why it suits swimming and phone-free training.
