If you want a single cable that turns your Audio-Technica M-series headphone into a long-reach, studio-friendly, coiled connection with a 1/4-inch adapter in the box, choose weishan ATH-M50x; if you need a complete wired headphone with a boom mic, a mute button and a volume limiter for a student or a teacher, choose SIMOLIO Headphones. These two products barely compete in the same category — one is a replacement cable, the other is a finished headset — so the real question is which job you actually need done.
• weishan ATH-M50x — biggest strength: a 2.5mm twist-lock to 3.5mm cable that stretches from about 4 feet coiled to roughly 14 feet, plus a 6.35mm adapter, so it covers both portable and studio gear.
• weishan ATH-M50x — biggest trade-off: it produces no sound on its own. It is a cable, not a headphone, and it only fits devices with the right 2.5mm and 3.5mm jacks.
• SIMOLIO Headphones — biggest strength: a complete over-ear wired headset with a 330° swiveling noise-reducing boom mic, one-key mute and a 3-level volume limiter (75/85/94 dB).
• SIMOLIO Headphones — biggest trade-off: it is wired only, with a fixed 1.5 m cord, so there is no wireless freedom, and its design leans toward younger users and school work.
• Who each pick is for: weishan for anyone whose M40x/M50x/M70x cable died or who needs a longer coiled lead; SIMOLIO for K-12 students, teachers and e-learning or call users who need a mic and hearing protection.
The weishan ATH-M50x cable is a very specific part: a 2.5mm three-pole male plug on one end, a 3.5mm three-pole male plug on the other, and a 6.35mm adapter included so the same cable can go into a laptop or into a mixer, amplifier or audio interface. Both tips are gold-plated, and the headphone end uses a twist-lock connection — the small detail that matters most, because it is what keeps the cable from pulling loose mid-session.
Where it earns its keep is reach and tidiness. The spring-coiled design sits at roughly 1.2 metres (4 feet) when relaxed and extends to about 4.5 metres (14 feet) when you actually need to walk across a room. That is the difference between a cable that snags on your chair and one that lets you step back from the desk without yanking your headphones off. The PVC jacket and copper conductor are aimed at stable signal transfer with low noise, and weishan lists it for studio mixing and tracking, DJing, FOH, mastering, post production and plain personal listening.
SIMOLIO Headphones: Who It's For
The SIMOLIO headset is a finished product with a clear audience: students, teachers and anyone who spends their day talking into a microphone. The standout feature is the boom mic. It swivels a full 330°, so you can wear the headphones on either side and flip the mic up and out of the way when you are just listening. The mic is unidirectional and noise-reducing, which means it focuses on the mouth rather than the room, and there is a one-key mute button right on the headset for instant silencing during a class, a call or an online chat.
The second feature parents and schools tend to care about is the 3-level volume limiter at 75 dB, 85 dB and 94 dB. That is a genuine safety design decision: the lower settings cap how loud the headphones can get, which matters for younger listeners and for long e-learning sessions. Sound is handled by a dynamic driver with a 20 Hz to 20,000 Hz frequency range and 94 dB sensitivity, and the over-ear plastic enclosure is built to be worn for extended periods.
Build-wise, the headband uses memory stainless steel strips, so it flexes and adjusts without feeling flimsy, and the whole thing folds down into a supplied pouch for the trip to school or on a plane. The cord is 1.5 metres (about 59 inches), and a Y-audio adapter is included so the headset works with laptops and PCs that split audio and mic into separate 3.5mm jacks. It is wired, it uses touch controls for volume, and it is aimed at ages 6 to 20 — so it is not a wireless headphone and not really designed for a commuting adult who wants active noise cancellation while walking. If you want that kind of product, the price on Amazon is worth checking before you commit, because the value question there is about the whole package, not one part.
• Best for replacing a broken M-series cable → weishan ATH-M50x. The 2.5mm twist-lock plug and 6.35mm adapter are the exact combination Audio-Technica M40x/M50x/M70x owners need.
• Best for microphone and calls → SIMOLIO Headphones. A 330° swiveling noise-reducing boom mic with one-key mute, which the weishan cable simply does not have.
• Best for long reach and cable management → weishan ATH-M50x. Coiled from about 4 feet out to roughly 14 feet, with a spring design that keeps slack out of the way.
• Best for hearing safety with kids → SIMOLIO Headphones. The 3-level limiter at 75/85/94 dB is a deliberate protection feature for younger users.
• Best for studio and gigging gear → weishan ATH-M50x. Mixing, tracking, DJing, FOH and mastering are the listed use cases, and the 1/4-inch adapter covers amps and interfaces.
• Best for school, travel and storage → SIMOLIO Headphones. Foldable frame, memory steel headband and a carrying pouch make it easy to pack.
• Best for device flexibility → SIMOLIO Headphones. A 3.5mm jack plus the Y-audio adapter covers phones, tablets, Chromebooks, laptops and desktops with split jacks.
• Best for someone who needs a complete, ready-to-use product → SIMOLIO Headphones. The weishan item is a component; you still need headphones to plug it into.
In my opinion, most people searching these two names together should buy the SIMOLIO Headphones, because it is a complete, working product the moment it arrives — mic, mute, volume limiter, folding frame and pouch all included. I would only pick the weishan ATH-M50x cable if I already owned an Audio-Technica M-series headphone and needed to replace or extend its cable; in that case it is the smarter, more targeted buy. So: buy SIMOLIO if you need headphones, buy weishan if you need a cable. Check the current price on Amazon for whichever one matches your situation before deciding.
No. The weishan item is a coiled replacement audio cable with a 2.5mm to 3.5mm connection and a 6.35mm adapter. The SIMOLIO item is a complete wired over-ear headset with a microphone. One is a part; the other is the whole product.
Will the weishan cable work with my Audio-Technica M50x?
Yes. They use a standard 3.5mm jack and include a Y-audio adapter for laptops and PCs with separate mic and audio jacks. The 1.5 m cord gives you room to move at a desk.
For that use case I would choose the SIMOLIO Headphones. The 3-level volume limiter (75/85/94 dB) protects young ears, the boom mic flips up when not needed, and the folding design plus pouch makes it easy to carry to and from school.
