How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a replacement cable built specifically for Bose QuietComfort and NC700 headphones with a 2.5 mm headphone-side plug, choose Cypher.V Replacement Aux Cable; if you need a 3.5 mm-to-3.5 mm cord for Beats by Dre headphones and game controllers, choose Fadmew Beat AUX Cord.
• Cypher.V's biggest strength: It solves a very specific problem — the odd 2.5 mm jack on Bose NC700, QC45, QC35II, QC35, QC25, OE2, OE2i, SoundTrue and SoundLink headphones — with gold-plated connectors and oxygen-free copper.
• Cypher.V's biggest trade-off: It's a single-purpose cable. The 3.5 mm-to-2.5 mm male-to-male layout won't work as a general-purpose aux cord for controllers, speakers or most phones.
• Fadmew's biggest strength: Broad device coverage — Beats Studio 3/2, Solo 3/2/Solo HD, Mixr, Pro, Detox, EP, Executive and Wireless — plus phones, laptops, tablets, PC, PS4 and Xbox One controllers, with a reusable cable tie included.
• Fadmew's biggest trade-off: It's a 3.5 mm-to-3.5 mm design, so it does nothing for Bose headphones that need the smaller 2.5 mm plug.
• Who Cypher.V is for: Bose owners replacing a lost or worn stock cable who want a plug-and-play fit without adapters.
• Who Fadmew is for: Beats owners and multi-device users who want one cord that moves between headphones, a laptop and a controller.
The Cypher.V cable exists for one reason: Bose headphones use a 2.5 mm jack on the headphone side, and almost nothing else in your house does. That single design decision shapes everything about it. One end is 3.5 mm for your phone, laptop, tablet, MP3 player or PC; the other is 2.5 mm for the headphone. Both are straight, gold-plated male plugs, wired with oxygen-free copper.
If you own NC700, QC45, QC35II, QC35, QC25, OE2, OE2i, SoundTrue or SoundLink headphones and your original cable has gone missing, frayed or started cutting out in one ear, this is the drop-in fix. No adapter, no guessing which end goes where — just plug and play. The listing also names Amazon Fire tablets among compatible devices, which matters if you watch or listen on a Fire HD 8 or Fire HD 10.
Build-wise, the Cypher.V uses a flexible TPE jacket that the maker describes as resistant to pulling and not easy to knot. At roughly 140 cm (4.6 ft) and just 11 grams, it's light enough to leave attached and forget about. Six pins, male-to-male, auxiliary connectivity — standard stuff, executed for a specific jack.
Fadmew Beat AUX Cord: Who It's For
Fadmew's cord is the generalist. It's a 3.5 mm-to-3.5 mm audio cable aimed at the Beats ecosystem first — Solo HD, Solo 3, Solo 2, Studio 3, Studio 2, Pro, Mixr, Detox, EP, Wireless and Executive — and then at basically everything else with a headphone jack. That includes Android and iOS phones (with a 3.5 mm port or adapter), laptops, tablets, PCs, PS4 controllers and Xbox One controllers.
The construction mirrors the OEM approach: oxygen-free copper conductors and gold-plated jacks. Fadmew's own framing is that this combination keeps audio clear, without hiss or muffling. I can't verify that by ear, but the materials are the same category you'd expect from a stock Beats cable, which is the point of a replacement.
Length is 4.6 ft (1.4 m) — the same figure as the Cypher.V, and Fadmew actually makes a case for it: short cords force you to hunch toward a desktop tower, long cords end up under your chair waiting to be yanked when you stand. That's a reasonable middle ground, and it's the length most people land on for desk and commute use.
The included reusable cable tie is a small thing that matters more than it sounds. Beats cables are notoriously stiff and prone to tangling in a bag; a tie you can loosen and re-tighten keeps the coil tidy whether it lives in a backpack, handbag or suitcase. Fadmew also states a 3-month window for quality-related issues handled by replacement or refund. That's a stated policy, not a durability guarantee — treat it as a floor, not a promise.
Skip this one if you own Bose headphones with a 2.5 mm jack, or if you specifically need an inline mic, which the listing doesn't claim.
Side-by-Side: Which Should You Choose?
• Best for Bose NC700 / QC35 / QC45 owners → Cypher.V Replacement Aux Cable. The 2.5 mm headphone-side plug is the whole reason it exists.
• Best for multi-device switching → Fadmew Beat AUX Cord. Headphones, phone, laptop, tablet, PC and console controllers all take the same 3.5 mm plug.
• Best for gaming controllers → Fadmew Beat AUX Cord. PS4 and Xbox One controllers are explicitly listed; the Cypher.V's 2.5 mm end isn't a controller plug.
• Best for a no-adapter replacement → Cypher.V Replacement Aux Cable. If you're replacing a Bose stock cable, this is plug-and-play on both ends.
• Best for bag-friendly storage → Fadmew Beat AUX Cord. The reusable cable tie is included; the Cypher.V relies on its TPE jacket staying tangle-free on its own.
• Best for cable length → a tie. Both are around 4.6 ft / 140 cm, so length isn't the deciding factor here.
• Best for calling → neither, based on the listings. The Cypher.V is explicitly a no-mic cable, and Fadmew doesn't claim an inline mic either.
In my opinion, the right buy comes down to which headphone brand you actually own — not to which cable is "better," because they're solving different mechanical problems. If you have Bose NC700, QC35, QC45, QC25 or any of the SoundTrue/SoundLink models, I'd buy the Cypher.V Replacement Aux Cable. The 2.5 mm plug is non-negotiable, the gold-plated oxygen-free copper build is what you want in a replacement, and the TPE jacket should hold up to daily coiling.
If you're on Beats — or you want one cord that also serves a laptop, a tablet and a PS4 or Xbox controller — I'd buy the Fadmew Beat AUX Cord. The reusable tie and the wider compatibility list make it the more flexible tool. Check the current price on Amazon before you commit, since that's the one thing a spec sheet can't tell you.
FAQ
It should, as long as your headphones use a standard 3.5 mm jack. Fadmew lists phones, laptops, tablets, PCs and PS4/Xbox One controllers as compatible. The Beats models are just the headline use case.
The Cypher.V is explicitly labeled "No Mic," and Fadmew's listing doesn't claim an inline mic. If you need to take calls through the cable, neither is the right pick based on the specs given.
Yes — the 3.5 mm end fits phones, MP3 and MP4 players, tablets, laptops and PCs with a 3.5 mm jack. Just remember the other end is 2.5 mm, so it only fits headphones that accept that smaller plug.
