How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want pure, no-fuss wired listening with a comfortable in-ear seal and a carry case in the box, choose Betron YSM1000; if you need a replacement coiled cable to bring an Audio-Technica M-series headphone back to life or to run a longer, tidier connection, choose weishan ATH-M50x.
• Betron YSM1000 — biggest strength: A complete, self-contained in-ear listening kit — aluminium housings, 9.2 mm dynamic drivers, memory-foam and silicone tips in three sizes, and a protective case.
• Betron YSM1000 — biggest trade-off: No microphone and no inline controls, so it's strictly for listening, not calls. It's also wired-only with a fixed 3.5 mm jack.
• weishan ATH-M50x — biggest strength: A 2.5 mm to 3.5 mm coiled replacement/extension cable with a 6.35 mm adapter, twist-lock connectors and gold-plated tips for a stable, low-loss signal.
• weishan ATH-M50x — biggest trade-off: It is a cable, not a headphone. It makes no sound on its own and only helps if you already own compatible gear.
• Who each pick is for: The Betron YSM1000 is for someone who wants to plug in and listen today. The weishan ATH-M50x is for someone repairing, extending or upgrading an existing headphone setup.
The Betron YSM1000 is a wired in-ear headphone built around one idea: listening, and nothing else. There's no microphone, no inline remote, no app to fiddle with — just a 3.5 mm jack, a 1.2 m tangle-free cord, and a pair of aluminium-bodied earpieces. Inside each housing sits a 9.2 mm dynamic driver tuned for what the spec sheet calls deep, micro-pressure balanced bass with natural tonality across genres. On paper the numbers back up the "easy to drive" pitch: 16 ohm impedance, 112 dB sensitivity, and a 20 Hz–20 kHz frequency range. Low impedance plus high sensitivity usually means a phone or laptop can push these to loud volumes without strain, which is exactly what you want from a commute pair.
What makes the YSM1000 genuinely useful for daily life is the fit system. You get small, medium and large silicone tips plus memory-foam tips, so you can dial in a seal that actually stays put. That seal is the whole trick here — it's passive noise isolation, not active cancellation. There's no ANC circuitry. But a good in-ear seal physically blocks a chunk of ambient sound and, as a side effect, firms up the bass response. For a bus, a train, a library or a noisy open-plan office, that's a real, tangible benefit. The aluminium housings and reinforced gold-plated jack suggest it's built to survive being shoved in a bag, and it ships with a protective case so the cable and tips aren't loose in your pocket.
weishan ATH-M50x: Who It's For
Now, a reality check that matters before you compare these two: the weishan ATH-M50x is not a pair of headphones. It's a cable. Specifically, it's a coiled aux cord with a 2.5 mm TRS male plug on one end and a 3.5 mm TRS male plug on the other, plus a 6.35 mm adapter in the box. It's aimed at owners of Audio-Technica M-series headphones — the M40x, M50x and M70x family — whose original cable has frayed, gone missing, or simply isn't the right length for the job.
The design choices make sense for that audience. The 2.5 mm end uses a twist-lock connector, which is the locking mechanism those headphones rely on, so the cable doesn't yank free mid-session. Both plugs are gold-plated, which the spec sheet ties to a better connection and "pure and transparent" signal transfer with reduced coloration. The wire itself is PVC-jacketed copper. Stretched out it's about 1.2 m, and coiled it extends to roughly 4.5 m — a 14 ft reach that lets you move around a desk, a studio floor or a couch without dragging your gear with you. The 6.35 mm adapter means you can plug into a guitar amp, a mixer or an audio interface's quarter-inch jack as well as a standard 3.5 mm port.
Compatibility is broad: the spec sheet lists PS4, PS5, Switch, Xbox One and Xbox Series X/S, MP3 players, laptops, PCs, phones, tablets, guitars and amplifiers — anything with a 3.5 mm or 6.35 mm port. The recommended uses read like a studio checklist: mixing and tracking, DJing, front-of-house, mastering, post-production, plus plain personal listening.
Who should buy it? Anyone whose M-series headphone cable has died, or who wants a longer coiled cable for studio or desk work and values the twist-lock security. Who should skip it? If you don't already own a compatible headphone or a device with a matching port, this cable does nothing for you. It's also a single cable — one unit, no spares — so heavy users may want a backup.
• Best for plug-and-play listening → Betron YSM1000. It's a finished product: drivers, tips, cable and case, ready to use.
• Best for fixing or extending existing gear → weishan ATH-M50x. It's a component, and only useful if you own the right headphone.
• Best for commuting and travel → Betron YSM1000. In-ear fit with memory-foam tips and passive isolation suits noisy journeys.
• Best for studio, DJ and desk work → weishan ATH-M50x. The coiled 4.5 m reach and 6.35 mm adapter are built for that environment.
• Best for calls → neither. The Betron has no mic, and the weishan cable has no mic either.
• Best for long-session comfort → Betron YSM1000. Multiple tip sizes let you tune the seal to your ears.
• Best value for a first purchase → Betron YSM1000. A complete kit is more useful than a cable if you own nothing yet.
• Best for a small, specific need → weishan ATH-M50x. If your cable is broken, this solves the problem cheaply and directly.
In my opinion, most people searching these two names together should buy the Betron YSM1000. It's the one that actually produces sound, it works out of the box with a phone, laptop or tablet, and the tip selection plus carry case make it a genuinely complete everyday package. The weishan ATH-M50x is the better buy only in one scenario: you already own compatible Audio-Technica M-series headphones and need a coiled replacement or extension cable. If you're starting from zero, a cable without a headphone is a dead end. Check the current price on Amazon for whichever one matches your situation.
Neither. The Betron YSM1000 has no built-in microphone or controls — it's designed purely for listening. The weishan ATH-M50x is a cable, not a headset, so it has no mic either.
No. It's a 2.5 mm to 3.5 mm coiled cable with a 6.35 mm adapter. It only works when connected between a compatible headphone and a device with a matching 3.5 mm or quarter-inch port.
No active noise cancellation. They rely on a secure in-ear seal to provide passive noise isolation, which reduces surrounding sound — memory-foam and three sizes of silicone tips help you achieve the best seal.
The Betron YSM1000, as long as your phone has a 3.5 mm jack or you use an adapter. It's a complete wired in-ear headphone with drivers, tips and a case. The weishan cable alone won't play anything.
