If you want to revive a pair of wired Beats headphones you already own, choose cipher Replacement Audio Cable; if you need a fully wireless, sweat-proof set of sport earbuds for running and workouts, choose PEFUPEW Earbuds. These two products barely compete for the same shopper — one is a 1.4-meter aux cord with an in-line mic, the other is a Bluetooth 5.4 pair of over-ear hook buds with a charging case — so the right answer comes down to what's already in your drawer.
• cipher Replacement Audio Cable — biggest strength: it's a direct, male-to-male 3.5mm cord built specifically for Beats Studio, Solo, Pro, Mixr, Executive and Pill models, with an in-line mic and remote so you keep call and volume control.
• cipher Replacement Audio Cable — biggest trade-off: it only works with devices that still have a 3.5mm jack, and it does nothing for you if your headphones are already wireless and healthy.
• PEFUPEW Earbuds — biggest strength: a genuinely self-contained wireless system — Bluetooth 5.4, up to 48 hours of total playback, IP7 waterproofing and four ENC mics in one package.
• PEFUPEW Earbuds — biggest trade-off: they're a hook-style sport bud, not a subtle everyday bud, and they won't help you fix a broken wired headphone.
• Buy the cipher cable if you already own compatible Beats cans and just need to replace a frayed or lost cord.
• Buy the PEFUPEW Earbuds if you want a standalone wireless set for the gym, running and calls, and you're starting fresh.
The cipher Replacement Audio Cable is a repair part, and it's honest about that. It's a 1.4-meter auxiliary cord with two male 3.5mm plugs — one straight, one right-angled (an "L" shape) — which is exactly the configuration Beats-style headphones use, since the angled end tucks neatly into the earcup and the straight end goes into your phone or laptop. The listed compatibility covers Beats Studio 2.0 and 3.0, Solo HD, Solo 2 and Solo 3, Pro, Mixr, Detox, Executive and Pill speakers, plus general audio devices with a 3.5mm jack like laptops, PCs, PS4/PS5 consoles, iPods and iPads.
Who should buy it: anyone with a pair of compatible Beats headphones whose original cable has died, gone missing, or started crackling, and who wants the cheapest sensible fix rather than a whole new set. It's also a reasonable spare to keep in a bag if you switch between a phone, a laptop and a console.
Who should skip it: if your headphones are Bluetooth and working fine, or if your phone has no headphone jack and you don't want a dongle, this cable solves nothing for you. It's also the wrong pick if you want wireless freedom at the gym — a cord is a cord.
PEFUPEW Earbuds: Who It's For
The PEFUPEW Earbuds are a completely different animal: a wireless sport earbud built around an over-ear hook, in a light blue colorway, made from ABS plastic with a charging case that measures roughly 5.5 by 3 by 8 centimeters and weighs 58 grams with the buds inside. There's no headphone jack at all — connectivity is Bluetooth 5.4 only, with a stated range of 15 meters and an audio transmission delay of just 40 milliseconds, which is the kind of low-latency number that matters if you're watching video or gaming and don't want lip-sync drift.
The audio hardware is a 14.2mm dynamic driver with 32-ohm impedance and a three-layer composite diaphragm, and PEFUPEW claims the design boosts bass by 43 percent while preventing distortion. On the call side, four ENC microphones are said to cut around 80 percent of background noise, which is the pitch you want if you take calls on a noisy street or in a gym. Battery life is the headline: up to 8 hours per bud at 50 percent volume, up to 48 hours total with the case topping you up four to five times, and a 1.5-hour charge time via USB-C. A dual LED display on the case shows charging status.
The fit story is the ear-hook. Flexible, soft hooks are designed to hold the bud in place during intense exercise, and the IP7 waterproof rating covers sweat and rain. Touch controls handle music and calls without reaching for your phone, and the box includes silicone ear tips in small, medium and large plus a USB-C cable and manual. A two-year warranty is listed.
Who should buy them: runners, gym-goers and anyone who wants a wireless set with long battery life, hook-based security and noise-cancelling mics for calls. Who should skip them: people who want a discreet, flush-fitting bud for office wear — hooks are visible — and anyone who prefers a wired connection for zero-latency monitoring.

• Best for wired, zero-latency listening → cipher Replacement Audio Cable. No pairing, no charging, no transmission delay — just plug in.
• Best for consoles, laptops and older iPods/iPhones → cipher Replacement Audio Cable. It works with anything that has a 3.5mm jack.

If I had to pick one for most people shopping today, I'd take the PEFUPEW Earbuds. In my opinion they're the more complete product: wireless freedom, a real 48-hour battery story, IP7 protection and ENC mics cover far more of daily life than a single replacement cord can. But I'd only say that to someone who needs earbuds. If you already own compatible Beats headphones and the cable is the only thing broken, buying the cipher cable is the smarter, more targeted move — you keep the sound you already like and fix exactly what failed. Check the current price on Amazon for whichever one matches your situation before you commit.
FAQ
If your compatible Beats headphones still work and only the cord is damaged, yes — it's a focused fix that restores the in-line mic and remote functions. If the drivers or battery are failing, a cable won't help.
Only the PEFUPEW Earbuds address noise at all, using four ENC microphones for calls plus passive noise cancellation and sound isolation. The cipher cable is a passive analog cord with no noise-cancelling function.
That's a sensible split. The cipher cable works with 3.5mm devices like PCs, PS4 and PS5, while the PEFUPEW Earbuds are designed for sport, running and workouts thanks to the ear hooks and IP7 waterproofing.
