If you want an all-in-one wired headphone for everyday listening, choose LORELEI X6; if you need a long 1/4-inch extension cable for a guitar, mixer or studio setup, choose TAISUSAN 1/4.
These two products get compared because they both turn up in "wired audio" searches — but they do completely different jobs. One is a set of over-ear headphones you wear on your head. The other is a 30-foot cable you plug between a quarter-inch device and something else. Here's how to decide which one actually belongs in your cart.
• LORELEI X6 — biggest strength: A complete, self-contained pair of wired over-ear headphones with a built-in mic, a 4-foot no-tangle cable and a foldable design you can toss in a bag.
• LORELEI X6 — biggest trade-off: It's a 3.5mm wired headphone with no noise cancellation and no wireless mode, so you're tethered and you'll hear the room around you.
• TAISUSAN 1/4 — biggest strength: A 30-foot male-to-female 1/4-inch stereo extension cable with gold-plated connectors and a braided, tangle-free jacket — it simply adds reach.
• TAISUSAN 1/4 — biggest trade-off: It makes no sound on its own. Without a source device and a quarter-inch jack, it does nothing at all.
• Buy LORELEI X6 if you want headphones for a phone, tablet or MP3 player.
• Buy TAISUSAN 1/4 if you need to stretch a 6.35mm connection across a room, stage or studio.
The LORELEI X6 is a straightforward wired headphone built around a 40mm dynamic driver with a 20 Hz–20 kHz frequency range. That's the standard full-range window for consumer audio, and a 40mm driver is a sensible size for over-ear bass delivery — which lines up with the "stereo bass" framing in the name. It's an on-ear design with round earpieces, a nylon-and-plastic enclosure in Space Black, and a listed weight of 7.25 ounces, which is light enough to wear for a long stretch without feeling like a brick on your head.
The practical details are where this one earns its keep. The cable is 4 feet with a no-tangle build, terminated in a standard 3.5mm jack, so it plugs straight into a smartphone, tablet, laptop or MP3/MP4 player with no adapter. There's a built-in microphone and button-based media controls on the cable, so you can take calls and skip tracks without digging your phone out. The whole thing folds and ships with a foldable case, and the age range covers both adults and kids — which makes it a reasonable pick for a student, a commuter or a parent buying a first pair for a child.
Who should skip it? Anyone who wants wireless freedom, active noise cancellation or a premium build. There's no Bluetooth here, no noise control at all, and the materials are nylon and plastic rather than metal and leather. If you need to block out a plane cabin or a noisy office, this isn't the tool. If you just want a cheap, dependable wired pair that folds flat and works with basically any 3.5mm device, it fits that job squarely.
The TAISUSAN 1/4 is not a listening device — it's a cable, and it should be judged as one. It's a 30-foot male-to-female 1/4-inch (6.35mm) TRS stereo extension cable, meaning one end is a quarter-inch male plug and the other is a quarter-inch female jack. It's bidirectional, so it works as an extension in either direction, and it uses three pins, which is what you'd expect from a stereo TRS connection rather than a mono instrument cable.
The build is the interesting part. TAISUSAN uses tinned copper conductors with gold-plated connectors, and the cable is made with an injection-molding and shielded manufacturing process intended to cut down EMI/RFI interference. The line diameter is 4.8mm, wrapped in soft PVC with an additional braided outer jacket for tangle resistance and longer service life. The color is grey and the shape is round.
Who should skip it? Anyone expecting sound. If you don't own a device with a 6.35mm jack, this cable is useless to you. And if you only need a couple of extra feet, 30 feet is a lot of cable to manage — though the braided jacket helps keep it from turning into a knot.
Side-by-Side: Which Should You Choose?
• Best for listening to music on a phone or tablet → LORELEI X6. It has the drivers, the 3.5mm plug and the mic.
• Best for extending a guitar, amp or mixer run → TAISUSAN 1/4. That's literally its entire purpose, across 30 feet.
• Best for taking calls → LORELEI X6. The built-in mic and button controls are the deciding factor.
• Best for long cable runs across a room or stage → TAISUSAN 1/4. Four feet versus thirty feet isn't close.
• Best for portability → LORELEI X6. It folds, ships with a case and weighs 7.25 ounces.
• Best for build materials → TAISUSAN 1/4. Gold-plated connectors, tinned copper and a braided, shielded jacket beat a nylon-and-plastic headphone frame on the cable front.
• Best for kids or students → LORELEI X6. Adult-and-kid sizing plus a tangle-free cable make it the friendlier first pair.
• Best for a studio or home-recording setup → TAISUSAN 1/4. Mixers, consoles and instruments all speak quarter-inch.
In my opinion, the honest answer is that these aren't really competitors — so I'd pick based on what's broken in your setup right now. If you need something to listen with, I'd buy the LORELEI X6: it's a complete, foldable, mic-equipped wired headphone that works with nearly any 3.5mm device, and the 40mm driver and 7.25-ounce build are exactly what a casual everyday pair should be. I'd only reach for the TAISUSAN 1/4 if you already own quarter-inch gear and your problem is distance, not sound. Buy the cable to solve reach. Buy the headphones to solve listening.
Wired. It connects over a 3.5mm jack with a 4-foot cable — there's no Bluetooth or wireless technology listed.
No. It's a 1/4-inch (6.35mm) male-to-female stereo cable, and phones use 3.5mm or USB-C. It's built for guitars, amps, mixers, consoles and quarter-inch headphones.
No. Noise control is listed as none, so it won't actively block background sound — it's a standard wired on-ear headphone.
They're built for different things, so it's not a clean comparison. The TAISUSAN cable uses gold-plated connectors, tinned copper and a shielded braided jacket; the LORELEI X6 is a nylon-and-plastic headphone that folds. Judge each against its own job.
