How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a no-nonsense wired replacement cord that brings a pair of Beats headphones back to life for movies, choose cipher Replacement Audio Cable; if you need a lightweight open-ear headset that keeps you aware of your surroundings while you watch, run or take calls, choose GZCRDZ Air Conduction Open. These two products sit in completely different corners of the audio world. One is a passive accessory — a piece of wire. The other is a finished listening device with its own drivers. That difference shapes everything below, so let's break it down honestly.
• cipher Replacement Audio Cable — biggest strength: it revives existing Beats Studio, Solo, Pro, Mixr, Executive and Pill hardware with a 1.4 m male-to-male cord, an in-line mic and remote, and a smart straight-plus-L plug layout.
• cipher Replacement Audio Cable — biggest trade-off: it makes no sound on its own. If you don't already own compatible Beats gear with a 3.5 mm jack, it does nothing for you.
• GZCRDZ Air Conduction Open — biggest strength: an 18 g open-ear design with earhooks, an IPX4 rating, a noise-reduction mic with mute, and a universal 3.5 mm plug that works with almost anything.
• GZCRDZ Air Conduction Open — biggest trade-off: open-ear audio leaks and lets the world in by design, so it will never give you the isolation of a sealed headphone.
• Pick the cipher cable if you're repairing or re-cabling headphones you already own.
• Pick the GZCRDZ if you want a complete, self-contained headset for movement, calls and casual listening.
This is a repair-and-revive product, and I mean that in the best way. The cipher cord is built for people who already own Beats headphones — Studio, Solo, Pro, Mixr, Executive — or a Beats Pill speaker, and whose original cable has frayed, gone missing or lost its remote. It's a 1.4 m linear cable with two male 3.5 mm plugs: one straight, one a right-angle L. That pairing is genuinely thoughtful. The straight end goes into your phone or laptop; the angled end tucks neatly into the earcup so it doesn't snag on a jacket or a chair arm.
Who should skip it? Anyone who doesn't own compatible Beats hardware, or anyone expecting a standalone listening device. It's a cord. It has no drivers, no battery, no Bluetooth. It also won't help if your headphones use a proprietary connector instead of a standard 3.5 mm jack. Buy it as a fix, not as a gadget.
GZCRDZ Air Conduction Open: Who It's For
The GZCRDZ is a different animal entirely: a complete wired headset that sits on the outside of your ear rather than inside it. The pitch is awareness. Because nothing blocks your ear canal, you hear traffic, doorbells and conversations while your audio plays alongside them. For running, cycling or driving, that's a real safety argument, not a marketing one. The ergonomic earhooks are there to keep the set stable through movement, and at 18 g — the sheet lists 15 g in one field and 18 g in the feature copy — it's about as light as a headset gets.
The spec sheet is interesting here. It lists a 16 Ω impedance, 116 dB sensitivity, a 20–200000 Hz frequency range, and a 16 mm driver described as bone conduction. That low impedance and high sensitivity combo means it should be easy to drive from a phone's headphone jack without an amp. You also get an in-line remote for playback, volume and calls, plus a noise-reduction microphone with a mute button — useful for online classes, live broadcasts or meetings where you need to kill the mic fast.
The honest trade-offs: it's wired, so there's no wireless technology at all, and the cable is a fixed 1.3 m rather than detachable. Noise control is listed as none, which makes sense for an open design. And with an open fit, bass will feel lighter than a sealed headphone and sound will bleed outward. If you want to disappear into a movie on a plane, this isn't the tool.
• Best for reviving Beats headphones → cipher Replacement Audio Cable. It's purpose-built for that exact job.
• Best for a complete listening device out of the box → GZCRDZ Air Conduction Open. Drivers, mic, remote and cable all included.
• Best for awareness and outdoor safety → GZCRDZ Air Conduction Open. The open design is the whole point.
• Best for movies on a wired Beats setup → cipher Replacement Audio Cable. If you already love your Beats sound, this is the cheapest way back to it.
• Best spatial audio ear clip headphones for movies → GZCRDZ Air Conduction Open. The earhook, open-ear form factor is the closest match to that category.
• Best open ear headphones for movies with situational awareness → GZCRDZ Air Conduction Open. You keep the soundtrack and the room at the same time.
• Best touch control sleep headphones for movies → neither, strictly speaking. The GZCRDZ uses push-button volume control, not touch, and neither product is marketed for sleep. If touch control is a hard requirement, keep looking.
• Best for calls and online class → GZCRDZ Air Conduction Open. The noise-reduction mic and mute button are the deciding features.
• Best for tangle-free everyday replacement cabling → cipher Replacement Audio Cable. Listed as tangle-free, with a length that suits desk and couch use.
If I had to buy one, I'd buy the GZCRDZ Air Conduction Open — but only because it's a complete product. It gives me audio, a mic, a remote and a universal 3.5 mm plug in one box, and its open-ear design is genuinely useful for running, cycling and staying aware while I watch something on a phone or laptop. For movies specifically, I'd reach for it when I want the soundtrack and the room at the same time. The cipher Replacement Audio Cable is the smarter buy if you already own Beats headphones and just need them working again. Two different jobs, two different answers.
No. It's designed for Beats Studio, Solo, Pro, Mixr, Executive, HD and Wireless on-ear models plus the Beats Pill, using standard 3.5 mm jacks. Check your model's connector before buying.
Yes, as long as your device has a 3.5 mm headphone jack. Newer phones without that jack will need an adapter, which isn't included.
If you already own compatible Beats headphones, the cipher cable restores that sound for movies. If you want a self-contained headset with awareness of your surroundings, the GZCRDZ is the better fit.
Price changes, so check the current price on Amazon before deciding. Judge them on function: the cipher is a repair part, the GZCRDZ is a full headset. Both are inexpensive ways to solve a specific problem.
