How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a tiny, set-and-forget adapter that turns a big 6.35mm jack into a 3.5mm socket on guitars, amps, mixers and receivers, choose VCE 3.5mm; if you need a full coiled headphone cable with a built-in 1/4-inch adapter for an Audio-Technica ATH-M50xBT-style wireless headset, choose weishan ATH-M50xBT.
• VCE 3.5mm biggest strength: a compact 6.35mm male to 3.5mm female TRS adapter with 24K gold-plated contacts, solid brass body and knurled grip — and it comes as a two-pack.
• VCE 3.5mm biggest trade-off: it is an adapter, not a cable. There is no cord, no length, and it does nothing for a headphone that needs a detachable lead.
• weishan ATH-M50xBT biggest strength: a full coiled 3.5mm-to-3.5mm TRS cable that stretches from about 4 ft to roughly 14 ft, with a 6.35mm adapter bundled in and twist-lock, gold-plated tips.
• weishan ATH-M50xBT biggest trade-off: it is a single cable built around one job (wired listening and studio work), so it is not the pick if you just need a stubby jack converter.
• Who VCE 3.5mm is for: anyone plugging a 3.5mm headphone or aux cable into a 6.35mm output — guitar amps, keyboards, mixers, receivers.
• Who weishan ATH-M50xBT is for: ATH-M50xBT / ATH-M50xBT2 and ATH-SR50BT owners who want a coiled wired cable for studio, DJ or desktop use.
The VCE 3.5mm is a small stereo adapter with a 6.35mm male plug on one end and a 3.5mm female socket on the other. In plain terms: it lets a device with a big 1/4-inch port talk to a device with a small 1/8-inch plug. Think about the everyday version of that. You have a headphone with a 3.5mm plug, but the only output in front of you is the 1/4-inch jack on an electric guitar amp, a bass amp, a keyboard, a digital piano, a studio monitor, an AV receiver or a mixer. The VCE sits in that gap. That is the whole point of it, and it does that job without a cable getting in the way.
The build is where this thing earns its keep. The contacts are 24K gold-plated, which VCE says maximizes conductivity and resists corrosion while cutting down signal loss and unwanted noise — the practical takeaway being a cleaner, truer stereo feed from pro-audio gear into personal listening gear. The body is solid brass with a precision-engineered TRS interface, so the plug seats firmly rather than wobbling. My favourite detail is the knurled, 360-degree grip treads: that non-slip texture matters a lot when you are reaching behind an amplifier or a mixer in a tight rack and can only feel your way in. You get a secure grip instead of fumbling.
It is also genuinely pocket-sized — roughly 1.77 x 0.39 x 0.39 inches and about 0.01 kg — so it disappears into a gig bag, a travel case or a jeans pocket and you forget it is there until you need it. The two-pack is the quiet win here: keep one on the amp at home and one in the bag. VCE backs it with an 18-month warranty, which is a reasonable signal for a part this small.
Who should skip it: if your problem is a missing or broken headphone cable, this is not your product. It adapts a jack; it does not replace a cord, and it will not add length or a coiled run to anything. If you need the cable itself, look at the weishan instead.
weishan ATH-M50xBT: Who It's For
The weishan ATH-M50xBT is a completely different animal: it is a cable, not an adapter. Specifically, it is a 3.5mm (1/8-inch) 3-pole TRS male-to-male coiled aux cord, and it ships with a 6.35mm (1/4-inch) adapter in the box. The headline number is length: it sits at roughly 1.2 metres (about 4 feet) coiled and extends out to about 4.5 metres (roughly 14 feet) when you stretch it. Wire diameter is 3.5mm.
That coil is the defining feature, and it is a smart one for the audience this cable is aimed at. A spring-coiled design stays tidy when you are not using it and gives you slack on demand when you are moving around. If you have ever had a straight cable snag on a chair leg mid-take or coil into a rat's nest in your bag, the spring format is the obvious answer. The connectors are twist-lock with gold-plated tips, which weishan says makes for a better connection and supports clean, transparent sound with sound-coloration cancellation. There is a 6.35mm adapter included, so the same cable can go from a phone or laptop into a mixer or amp jack without hunting for a second part.
Construction is premium PVC and copper wire, and weishan positions it for studio mixing and tracking, DJing, front-of-house, mastering, post production and plain personal listening. That list tells you who it is really for: someone who wants one reliable cable that moves between a desk setup and a live or studio context. Compatibility is wide — PS4, PS5, Switch, Xbox One, Xbox X/S, MP3 players, laptops, PCs, phones, tablets, guitar and amplifier, anything with a 3.5mm or 6.35mm port. It is also a male-to-male 3-pole cable, so it is a straight stereo link between two jacks rather than a headset mic cable.
Who should buy it: Audio-Technica ATH-M50xBT and ATH-M50xBT2 owners, plus ATH-SR50BT users, who want a coiled wired cable for studio, DJ or desktop listening and like the idea of the bundled 1/4-inch adapter. It also suits anyone who wants one versatile coiled aux cable for consoles, laptops and controllers.
Who should skip it: if you only need to convert a 6.35mm socket to a 3.5mm plug, this is overkill — you would be paying for a cable you do not need. And if you want a straight, non-coiled run, the spring design is not what you are after. For that narrow job, the VCE is the cleaner fit.
• Best for converting a 6.35mm jack to 3.5mm → VCE 3.5mm. That is literally its single function, and it does it with gold plating and a brass body.
• Best for replacing or upgrading a headphone cable → weishan ATH-M50xBT. It is a full 3.5mm male-to-male cord with a bundled 1/4-inch adapter.
• Best for reach and slack → weishan ATH-M50xBT. Roughly 4 ft coiled, stretching to about 14 ft.
• Best for pocketability and travel → VCE 3.5mm. Under two inches long and about 0.01 kg, and you get two of them.
• Best for studio, DJ and FOH work → weishan ATH-M50xBT. The coiled format and PVC/copper build are aimed squarely at mixing, tracking and live use.
• Best for grip in tight spaces → VCE 3.5mm. The knurled 360-degree treads are designed for exactly that reach-behind-the-rack moment.
• Best for ATH-M50xBT / M50xBT2 / ATH-SR50BT owners → weishan ATH-M50xBT. It is built and named for that headphone family.
• Best if you want a spare → VCE 3.5mm. The two-pack means one lives on the amp and one lives in the bag.
In my opinion, these two are not really rivals — they solve different problems, so I would pick based on the job. If your issue is a jack mismatch, I would buy the VCE 3.5mm: it is small, brass-built, gold-plated, easy to grip and you get two. If your issue is a missing or worn cable on an ATH-M50xBT-style headphone, I would buy the weishan ATH-M50xBT — the coiled 4-to-14 ft run and bundled 6.35mm adapter make it the more useful single purchase for studio and DJ work. Forced to choose one for the widest range of buyers, the weishan does more per purchase; for the pure adapter job, the VCE wins.
FAQ
It is designed for the Audio-Technica ATH-M50xBT and M50xBT2 and also lists ATH-SR50BT compatibility. It uses a 3.5mm 3-pole TRS male plug at each end with twist-lock, gold-plated tips, plus a 6.35mm adapter.
The weishan runs about 4 feet coiled and extends to roughly 14 feet. The VCE is the one for a guitar or bass amp: its 6.35mm male plug goes into the amp's 1/4-inch output and its 3.5mm female socket accepts a standard headphone or aux plug.
I do not quote prices here — both listings can change, so check the current price on Amazon using the button on this page. On features, the VCE gives you two brass, gold-plated adapters with an 18-month warranty, while the weishan gives you a coiled 4-to-14 ft cable plus a 6.35mm adapter, so each is fair value for its own job.
