If you want an open-ear design that keeps you aware of traffic, voices and everything else around you, choose GZCRDZ Air Conduction Open; if you need deep, immersive over-ear sound with a foldable travel-friendly body, choose Botesty Sound Headphones. Both are wired, both use a 3.5mm jack, and both are aimed at very different buyers. This comparison breaks down exactly where each one wins and where it falls short.
• GZCRDZ Air Conduction Open — biggest strength: open-ear design (18g, IPX4) that leaves your ear canal completely free, so you hear music and the world around you at the same time.
• GZCRDZ Air Conduction Open — biggest trade-off: it's wired only over a fixed 1.3m cable, has no noise isolation at all, and the inline remote handles volume but nothing else.
• Botesty Sound Headphones — biggest strength: 40mm dynamic drivers in an over-ear cup, tuned for deep bass and clear sound, with a tangle-free 4.9ft nylon cord.
• Botesty Sound Headphones — biggest trade-off: it's a closed over-ear headphone, so no ambient awareness, and volume must be adjusted on your device — the headphone buttons won't do it.
• Who each is for: pick the GZCRDZ if you run, cycle, drive or need to stay alert outdoors; pick the Botesty if you want to disappear into music on a plane, in a library or at a desk.
The GZCRDZ Air Conduction Open is built around one idea: don't seal the ear. The earpiece rests flat or slightly curved on the outer ear, held in place by ergonomic earhooks, so nothing blocks your ear canal. That single design decision changes everything about how you'd use it. When you're running a road with traffic, cycling a bike lane, or even driving, you can hear the music or audiobook and still catch a car horn, a bell or a voice behind you. For outdoor activity, that awareness isn't a gimmick — it's the whole point of the product.
At 18g with an IPX4 rating, it's made to handle rain and sweat without complaint, and the lightweight body means it stays comfortable through long sessions. The spec sheet lists a 16Ω impedance and 116±3dB sensitivity, which tells me it's an easy load — the kind of headphone a phone or laptop drives without strain. The 16mm driver and 20–200000Hz frequency range handle music, calls and spoken content. There's also a built-in noise-reduction microphone with a mute button, which is genuinely useful for online classes, live broadcasts or hands-free calls, plus inline push-button volume control on the cable.
Who should buy it: runners, cyclists, drivers, delivery riders, gym-goers and anyone who takes calls while moving. It's also a sensible pick for online class, listening to lectures or live streaming, because the mic and mute switch are right there on the wire. Who should skip it: anyone who wants to block out a noisy commute, an airplane cabin or a crowded office. With an open design and no noise control, you'll hear everything — which is either the feature you want or the dealbreaker you don't.
The Botesty Sound Headphones go the opposite direction. These are over-ear, closed cups with 40mm dynamic drivers and a 20Hz–20KHz frequency response, and over-ear designs are exactly what you want when the goal is deep bass and an immersive listen. Because the cups surround the ear rather than sit beside it, sound stays in and outside noise stays out — a completely different experience from the open GZCRDZ.
The build is clearly aimed at travel and commuting. The 4.9ft nylon braided cord resists tangling, the 120° curved plug is designed for durability, and the whole thing folds up so you can drop it into a bag or suitcase. That combination — folding body, long tangle-free cable, over-ear cups — makes it a natural fit for airplanes, trains, school and laptop work. A 3.5mm jack means it plugs into most phones, tablets, laptops, Kindles and MP3/MP4 players.
Two things you need to know before buying. First, volume can only be adjusted on the connected device — the headphone controls won't change it. Second, if your device has no 3.5mm jack, you'll need a conversion adapter, and some adapters don't pass the mic through, so the microphone may not work. Botesty lists a 6-month warranty, which is shorter than the GZCRDZ's 1-year coverage.
Who should buy it: students, commuters, frequent flyers, and anyone who wants one pair of foldable wired headphones for a laptop and a plane ride. Who should skip it: runners and cyclists who need to hear their surroundings, and anyone who hates juggling adapters.
• Best for outdoor safety and traffic awareness → GZCRDZ Air Conduction Open (open ear, nothing blocks your surroundings).
• Best for immersive bass and closed-off listening → Botesty Sound Headphones (40mm dynamic over-ear drivers).
• Best for running, cycling and sweaty workouts → GZCRDZ Air Conduction Open (18g, IPX4, earhook fit).
• Best for travel, school and long commutes → Botesty Sound Headphones (foldable body, 4.9ft tangle-free nylon cord).
• Best for calls and online class → GZCRDZ Air Conduction Open (noise-reduction mic with mute button).
• Best for device volume control convenience → neither, really — GZCRDZ has inline volume buttons, Botesty requires you to adjust on the device.
• Best for warranty coverage → GZCRDZ Air Conduction Open (1-year vs 6-month).
• Best for fitting in a bag → Botesty Sound Headphones (folds up; GZCRDZ is a fixed earhook design).
In my opinion, the right pick comes down to one question: do you need to hear the world, or do you want to shut it out? If you're moving — running, riding, driving, taking calls on the go — I'd buy the GZCRDZ Air Conduction Open. The open-ear fit, 18g weight, IPX4 rating and built-in mic make it the more versatile companion for active use, and the 1-year warranty is a point in its favor. If you're stationary — a plane seat, a desk, a lecture hall — I'd take the Botesty Sound Headphones for the deeper, more immersive over-ear sound and the foldable travel body. Neither is universal. Match it to how you actually listen.
FAQ
The GZCRDZ. It's designed for exactly that: 18g, IPX4 sweat and rain resistance, earhooks for a secure fit, and an open design so you hear traffic and bells while you run. The Botesty is an over-ear headphone built for immersive listening, not movement.
No. The spec sheet lists no noise control. They're closed over-ear cups, which naturally blocks some outside sound, but there's no active noise cancellation. The GZCRDZ also lists no noise control — its open design deliberately lets sound in.
On the GZCRDZ, yes — the inline remote has push-button volume control. On the Botesty, no — Botesty states volume can only be adjusted on the connected device.
Both use a 3.5mm jack, so they work with most phones, tablets and laptops that have the port. If your device has no 3.5mm jack, you'll need a conversion adapter — and note that some adapters don't support the microphone, so the mic may not work on the Botesty.
