If you want a coiled replacement cable that fixes a broken or too-short ATH-M50xBT connection, choose weishan ATH-M50xBT; if you need a complete pair of wired in-ear monitors for studio, stage or daily listening, choose YINYOO CCZ Melody.
• weishan ATH-M50xBT — biggest strength: a spring-coiled 3.5mm TRS cable with a 6.35mm adapter, twist-lock plugs and gold-plated tips, built for Audio-Technica wireless headphones and just about anything else with a 3.5mm or 6.35mm socket.
• weishan ATH-M50xBT — biggest trade-off: it is not a headphone. You get no drivers, no earpieces, no sound of its own — just one cable and one adapter.
• YINYOO CCZ Melody — biggest strength: a genuine 1DD + 1BA hybrid IEM with a detachable 2-pin cable, 2.3g-per-side shells and a wrap-around fit that stays put.
• YINYOO CCZ Melody — biggest trade-off: wired only, and the listing's remote buttons do not control volume — you get play/pause/skip and calls, nothing more.
• Who each is for: the weishan cable is for someone who already owns ATH-M50xBT or ATH-M50xBT2 headphones and needs a longer, tidier lead; the YINYOO Melody is for someone who needs the earphones themselves.
This is a cable, not a headphone, and that distinction decides everything. The weishan ATH-M50xBT is a coiled aux cord that runs from roughly 1.2 meters relaxed out to about 4.5 meters stretched, with a 3.5mm wire diameter and male-to-male 3-pole TRS plugs at both ends. One end carries a twist-lock collar designed to seat properly in the ATH-M50xBT and ATH-M50xBT2 sockets; the other plugs into a phone, laptop, tablet, console controller, amp or interface. A 6.35mm adapter is included, which is the part that matters if you're plugging into a mixing desk, a headphone amp or a home stereo receiver.
What it does best is solve one very specific annoyance. If your stock cable is too short, tangled, or has started cutting out on one channel, this replacement restores a stable signal path without you buying new headphones. The coiled spring design keeps the slack gathered instead of pooling on your desk, and the 14-foot reach is genuinely useful in a studio or DJ setup where you want to move between a rack and a chair. The gold plating and twist-lock fitting are the sort of details that help keep the connection seated during tracking and mixing sessions, and the PVC-and-copper construction is aimed at low-noise, low-loss transmission.
Who should buy it: anyone with ATH-M50xBT or ATH-M50xBT2 headphones who wants a longer cable, a coiled cable that doesn't drag, or a spare to keep in a bag. It also works as a general-purpose aux lead for a long list of devices with 3.5mm or 6.35mm ports. Who should skip it: anyone who doesn't already own compatible headphones, anyone who needs a microphone or inline controls — this cable has neither — and anyone who wants a straight cable rather than a coil. If you're shopping for a listening experience rather than a repair, this isn't your product.
The YINYOO CCZ Melody is an actual pair of in-ear monitors, and the spec sheet is unusually specific for the category. It's a hybrid design: one dynamic driver for the low end plus one balanced armature driver, rated at 16 ohm impedance, 110 dB sensitivity and a 20–20kHz frequency range. That low impedance and high sensitivity combination means it doesn't demand much power, so a phone, a laptop or a basic player can drive it without a separate amp.
The physical design leans hard into comfort. Each earpiece weighs 2.3 grams, the PC cavity is finished with UV varnish in a purple colorway, and there's a groove at the ear cap that the maker says opens up the stereo image and detail. The ear tips are soft TPE in three sizes, and the short sound guide tubes are there to reduce sound loss. A TPE ear fin sits behind the cavity and a memory ear hook holds its shape around your ear — that wrap-around arrangement is the reason these stay in during movement, which is the practical difference between an IEM you can wear at a drum kit or on a run and one that pops out.
The cable is detachable via a 2-pin connector, which is a real long-term advantage: if the cable wears out or you want a different one, you swap it rather than replacing the earphones. It's a 4-core 4N OFC wire, and the 3.5mm plug works with phones, MP3/MP4 players, speakers and basically any 3.5mm source. Note the version: this is the without microphone model, so the inline mic and remote controls described in the broader listing don't apply here — if you need call handling, look at the mic version instead.
Who should buy it: singers, drummers, musicians and anyone who wants a wired hybrid IEM for stage or studio use with a secure fit and a replaceable cable. Also a sensible pick for studying, commuting or gaming on a 3.5mm jack. Who should skip it: anyone who wants wireless, anyone who needs inline controls or a microphone, and anyone who dislikes the feel of a wrap-around ear hook.
• Best for replacing a broken or too-short headphone cable → weishan ATH-M50xBT. That's literally what it's made for.
• Best for actually listening to music → YINYOO CCZ Melody. It has drivers; the weishan doesn't.
• Best for studio and DJ desk work → weishan ATH-M50xBT, thanks to the 14-foot coiled reach and the included 6.35mm adapter.
• Best for a secure fit on stage or while moving → YINYOO CCZ Melody, with its ear fins, memory hooks and three tip sizes.
• Best for long-term repairability → YINYOO CCZ Melody. The 2-pin detachable connector means a worn cable is a cheap swap, not a dead product.
• Best for broad device compatibility → a tie, with different targets. The weishan spans 3.5mm and 6.35mm ports across consoles, amps and computers; the Melody covers any standard 3.5mm jack.
• Best for a picky, low-power source → YINYOO CCZ Melody, at 16 ohm and 110 dB it's easy to drive straight from a phone.
• Best if you need a microphone or inline controls → neither of these exact versions. The weishan cable has no mic, and the Melody here is the non-mic variant.
In my opinion these two products shouldn't really be competing — they solve different problems, and picking the wrong one wastes your money. If you own ATH-M50xBT or ATH-M50xBT2 headphones and your cable is the problem, I'd buy the weishan ATH-M50xBT without hesitation; it's purpose-built for that socket and gives you a longer, tidier, better-seated connection. But if you're actually shopping for earphones to listen with, I'd buy the YINYOO CCZ Melody. A hybrid 1DD + 1BA IEM with a detachable cable and a fit designed to stay put is simply a more useful object for most people, and the replaceable cable gives it a longer life. Check the current price on Amazon before you decide, and make sure you order the version that matches your needs — mic or no mic.
FAQ
The version described here — the purple "without microphone" model — does not. It's the wired, non-mic variant, so if you want call handling you need to look at the mic version of the same earphone.
It depends on the job. For tracking, mixing or DJing with existing Audio-Technica headphones, the weishan cable gives you the reach and the 6.35mm adapter. For monitoring in-ear as a singer or drummer, the Melody's hybrid drivers and wrap-around fit make it the more appropriate tool.
Yes, as long as your phone has a 3.5mm headphone jack. At 16 ohm and 110 dB it's easy to drive from a phone or laptop. If your phone has no headphone jack, you'll need an adapter, which isn't included.
