If you want a complete wired headphone you can unbox and use for commuting right away, choose Coby Over-Ear Headphones; if you need a replacement aux cable to bring a pair of Sony wireless headphones back into wired duty, choose Asobilor 4.9FT. That single sentence is the whole comparison in miniature — one product is a finished headset, the other is a single component that only makes sense if you already own the right headphones. Everything below explains why I land there, and who should ignore my advice.
• Coby Over-Ear Headphones — biggest strength: A complete, plug-and-play wired headset with a built-in mic, a one-touch call button, passive noise isolation and a 3.5mm jack that works with laptops, tablets, Chromebooks and MP3 players.
• Coby Over-Ear Headphones — biggest trade-off: It's a wired-only, plastic-bodied design with a 90-day manufacturer warranty, so it's built for simple everyday listening and calls rather than premium materials or wireless freedom.
• Asobilor 4.9FT — biggest strength: A 4.9ft (1.5m) male-to-male aux cable with gold-plated connectors, high-purity copper wire and a PVC jacket with strain relief, made to fit a specific list of Sony wireless models.
• Asobilor 4.9FT — biggest trade-off: It is a cable and nothing else. No drivers, no mic, no earcups — if you don't own one of the compatible Sony headphones, it does nothing for you.
• Who each pick is for: Coby for someone who needs an affordable, ready-to-use wired headset for commuting, school or office calls; Asobilor for a Sony WH-1000XM or WH-CH owner whose stock cable is lost, frayed or too short.
The Coby Over-Ear Headphones are a straightforward wired headset, and that simplicity is the point. You get over-ear cushioned earcups, an adjustable headband, a 3.5mm aux jack and an integrated microphone with a one-touch button. Because it runs on a cable rather than a battery, there's no charging routine to remember — you plug in and it works. The dynamic drivers cover a 20Hz–20,000Hz range at 32 ohm impedance, and Coby leans into amplified low frequencies, which is why the brand markets it as "Super Bass." For pop, hip-hop, podcasts and video audio, that tuning is a sensible match.
Who should skip it? Anyone who wants wireless listening, active noise cancellation, or a premium-feeling build. The enclosure is plastic, the control method is listed as touch, and the warranty runs 90 days from the manufacturer. If you need to move around a room untethered, or you want a headset that doubles as a serious gaming rig for long sessions, this isn't the tool. It's a dependable, low-fuss wired headset for focus, calls and casual listening — not a flagship.
Asobilor 4.9FT: Who It's For
The Asobilor 4.9FT is not a headphone. It's a replacement audio cable, and reading it as anything else will lead you to the wrong conclusion. It's a 4.9-foot (1.5m) aux cord with standard 3.5mm male-to-male connectors, three pins, and a grey PVC jacket with strain relief at the ends. Asobilor specifies high-purity copper wire and gold-plated connectors for stable signal transmission, and the whole point is clear, lossless audio rather than any kind of tuning or processing. A cable can't add bass or cancel noise — it can only avoid getting in the way.
The compatibility list is the deciding factor. Asobilor designed it for Sony WH-1000XM6, XM5, XM4 and XM3, plus WH-CH510, WH-CH710N, WH-CH700N and WH-XB910N. If you own one of those, this is a direct-fit replacement that restores wired listening — handy when a battery is drained, when you're on a plane with a seatback screen, or when you simply prefer a cable for zero-latency monitoring. The 4.9ft length gives you comfortable slack between your head and a phone, tablet, laptop or MP3 player on a desk or tray table.
Who should skip it? Anyone who doesn't own a compatible Sony model, and anyone hoping to "upgrade" a cheap pair of headphones into something better. It's also indoor/outdoor rated for audio transmission only — no mic, no inline controls, no charging. The heat-resistant build and strain relief suggest it's meant to survive being coiled into a bag repeatedly, which is exactly the failure point on most stock cables. If that's your problem, this is a clean fix.
Side-by-Side: Which Should You Choose?
• Best for replacing a lost or frayed Sony cable → Asobilor 4.9FT. It's purpose-built for the WH-1000XM and WH-CH/WH-XB families.
• Best for calls, classes and meetings → Coby Over-Ear Headphones. The integrated mic and one-touch button are the whole reason to pick it over a bare cable.
• Best for passive noise reduction on a bus or plane → Coby Over-Ear Headphones. The cushioned over-ear padding physically blocks some outside sound.
• Best for long cable runs at a desk → Asobilor 4.9FT. 4.9ft of slack beats a short stock cord when your laptop sits across the desk.
• Best for travel durability → Asobilor 4.9FT. PVC jacket plus strain relief is designed to survive repeated bending and packing.
• Best for kids, teens and shared classroom devices → Coby Over-Ear Headphones. The adjustable headband and universal aux jack fit a range of head sizes and devices.
• Best if you already own compatible Sony headphones → Asobilor 4.9FT. You'd be paying for hardware you don't need with the Coby.
For most people reading this, I'd buy the Coby Over-Ear Headphones. It's the only one of the two that is an actual listening device — mic, earcups, adjustable headband, 3.5mm plug, done. For commuting specifically, the combination of passive noise isolation and a built-in mic covers the two things you'll actually use on a train or bus. The one clear exception: if you already own a compatible Sony WH-1000XM or WH-CH headphone and just need a longer, tougher cable, the Asobilor 4.9FT is the smarter, more targeted buy. In my opinion, match the product to what you already have in your bag — that's the real decision here. Either way, check the current price on Amazon before you commit, since that's the one variable I can't speak to.
how to make aux cable with headphones
You don't build one — you match connectors. An aux cable like the Asobilor 4.9FT uses standard 3.5mm male-to-male plugs, so it connects a headphone's 3.5mm input to a phone, laptop or tablet's 3.5mm output. If your headphones already have a fixed cable and a 3.5mm plug, like the Coby, no extra cable is needed at all.
how to use wired headphones without headphone jack
You need an adapter, not a different headphone. Many phones and slim laptops dropped the 3.5mm port, so a USB-C or Lightning-to-3.5mm adapter bridges the gap. Both products here rely on a standard 3.5mm connection, so the adapter sits between your device and the plug.
how do i connect my wired headphones to my phone
Plug the 3.5mm jack into your phone's headphone port and you're done — the Coby is plug-and-play with no pairing or charging. If your phone has no headphone jack, use a USB-C or Lightning adapter. The Asobilor cable works the same way, connecting a compatible Sony headphone to the phone's audio output.
No. The Coby Over-Ear Headphones come with their own cable and a 3.5mm aux jack, so they're ready to use as-is. The Asobilor 4.9FT only makes sense as a replacement for specific Sony wireless models whose original cable is lost, damaged or too short.
