If you want one cable that takes a standard 3.5mm stereo signal and plugs it into a 6.35mm (1/4") jack on a guitar amp, mixer, keyboard or home-theater device, choose Ugreen 3.5mm; if you need a dedicated replacement cord for a Sennheiser GAME ONE, GAME ZERO, PC 373D, GSP 350, GSP 500 or GSP 600 gaming headset, choose Alitutumao Replacement Aux Cable. These two look similar in a search results page — both are braided black aux cables — but they solve completely different problems. One is a 3.5mm-to-1/4" adapter cable. The other is a headset-specific replacement cord with a 2.5mm headphone plug and dual 3.5mm ends. Buying the wrong one is the single most common mistake here.
• Ugreen 3.5mm — biggest strength: a genuine 3.5mm-to-6.35mm stereo conversion cable with 24K gold-plated connectors, double shielding and a zinc alloy housing, built for instrument, mixer and amplifier duty.
• Ugreen 3.5mm — biggest trade-off: the connector format is fixed. It is 3.5mm male to 1/4" male only — it is not a 1/4"-to-1/4" cable, not a 1/8"-to-1/8" cable, and it will not fit a headset that needs a 2.5mm plug.
• Alitutumao Replacement Aux Cable — biggest strength: a purpose-built replacement cord for specific Sennheiser gaming headsets, with the exact 2.5mm-to-dual-3.5mm connector layout those headsets use, in a 2 m tangle-free braided build.
• Alitutumao Replacement Aux Cable — biggest trade-off: it is not a general-purpose aux cable. Its 2.5mm headphone-side plug means it only makes sense if you own one of the listed Sennheiser models.
• Who each pick is for: Ugreen 3.5mm for anyone bridging a phone, laptop, tablet or headphone jack into 1/4" studio, stage or hi-fi gear. Alitutumao Replacement Aux Cable for Sennheiser GAME/GSP-series owners who need to replace a lost or worn original cord.
The Ugreen 3.5mm cable does one job and does it in a fairly serious way: it carries a stereo 3.5mm signal into a 6.35mm jack. That means a laptop, phone, tablet, MP3 player or a set of 3.5mm headphones on one end, and a guitar amp, mixing console, home theater device, speaker or amplifier on the other. It is 6.6 feet long, round, black, and finished with a zinc alloy shell plus a double-layer nylon braid — the kind of build that tolerates being yanked across the edge of an amp or coiled into a gig bag.
Here is the part most buyers get wrong, and it is worth repeating because the product notes say it plainly. This is a 3.5mm to 1/4" male-to-male cable. It is not a 1/4"-to-1/4" instrument cable, not a 1/8"-to-1/8" cable, and not a 2.5mm cable of any kind. Also, an electric guitar outputs a mono signal by design — it is not a stereo source — so if you want a stereo setup from a guitar you need an amp in the chain. And when you patch into a mixer, use the stereo input/output port rather than a mono one. On the "no-loss, high-fidelity" claim: for true stereo output, your playback device has to actually support stereo processing.
Buy the Ugreen 3.5mm if you are connecting a computer, phone, tablet or 3.5mm headphone output to 1/4" gear — keyboards from Yamaha, Casio and Roland, digital pianos, bass amplifiers, recorders, mixers, speakers, AV receivers or home theater devices. Skip it if your source and destination are both 1/4", both 1/8", or if you are trying to replace a cable on a headset that uses a 2.5mm plug. In those cases this is simply the wrong connector, no matter how good the build is.
Alitutumao Replacement Aux Cable: Who It's For
The Alitutumao Replacement Aux Cable is not a general aux cable at all — it is a replacement part. It is made specifically for Sennheiser G4ME ONE, G4ME ZERO, GAME ONE, GAME ZERO, PC 373D, GSP 350, GSP 500 and GSP 600 gaming headsets. If you own one of those and your original cable has gone missing, developed a crackle, or been chewed by a pet, this is the direct swap.
The connector layout is the whole point. On the headphone side there is a mini 2.5mm stereo plug. On the other end there are two 3.5mm stereo plugs that go to your computer or console. That 2.5mm-to-dual-3.5mm arrangement is unusual — it is not something you can substitute with a normal 3.5mm aux cord — which is why a dedicated replacement cable exists for these headsets in the first place.
The build is 2 meters, roughly 6.5 feet, in black nylon-woven material with what Alitutumao describes as a professional enwind design, plus oxygen-free copper and multi-strand cores. The special features listed are braided, retractable and tangle-free — useful traits for a cable that lives on a desk, gets coiled into a drawer, or travels in a backpack between PC, PS4, Xbox One, Mac, mobile and tablet use.
Buy the Alitutumao Replacement Aux Cable if you own a listed Sennheiser GAME or GSP headset and need a working cord again, in a tangle-resistant 2 m length. Skip it if you are looking for a general-purpose 3.5mm aux cable, or if your headset is not on the compatibility list. The 2.5mm plug will not fit a standard 3.5mm headphone jack, and there is no adapter trick that makes that work in this package.
• Best for 3.5mm-to-1/4" connections → Ugreen 3.5mm. This is the cable's entire purpose, and the gold-plated, double-shielded design is aimed squarely at that signal path.
• Best for Sennheiser GAME/GSP headset replacement → Alitutumao Replacement Aux Cable. The 2.5mm-to-dual-3.5mm layout matches those headsets specifically.
• Best for guitar amp, mixer, keyboard or home theater → Ugreen 3.5mm. Compatibility explicitly covers Yamaha, Casio and Roland keyboards, digital pianos, mixers, speakers, bass amplifiers and AV gear.
• Best for PC, PS4, Xbox One and mobile gaming with a Sennheiser headset → Alitutumao Replacement Aux Cable. The listed compatible devices are exactly those platforms.
• Best for a longer reach → Alitutumao Replacement Aux Cable. At 2 meters it edges out the 6.6-foot Ugreen, though the two are close in practical terms.
• Best for connector durability → Ugreen 3.5mm. Zinc alloy housing plus double-layer nylon braid is the more ruggedly specified shell of the two.
• Best for tangle resistance on a desk → Alitutumao Replacement Aux Cable. Its listed special features include retractable and tangle-free behavior alongside the braid.
• Best for a stereo line-level run → Ugreen 3.5mm. Pure copper core and double shielding are designed to keep a left/right signal clean into an amp or console.
In my opinion, the deciding factor is your connector, not the cable quality — both are braided, oxygen-free-copper designs with reasonable shielding, and neither is the weak link in a normal setup. If you are wiring a phone, laptop, tablet or headphone jack into a 1/4" amp, mixer, keyboard or home theater device, I would buy the Ugreen 3.5mm. Its 3.5mm-to-6.35mm format is exactly what that job needs, and the zinc alloy housing and double shielding give it the edge for stage and studio use. If you own a Sennheiser GAME ONE, GAME ZERO, PC 373D, GSP 350, GSP 500 or GSP 600, I would buy the Alitutumao Replacement Aux Cable instead — it is the only one of the two that will physically plug into your headset.

FAQ
No. It is built for specific Sennheiser models — G4ME ONE, G4ME ZERO, GAME ONE, GAME ZERO, PC 373D, GSP 350, GSP 500 and GSP 600. It uses a 2.5mm plug on the headphone side and two 3.5mm plugs on the device side, so it will not fit headsets with a standard 3.5mm input.
Ugreen specifies double shielding, gold-plated connectors and a pure copper core, all aimed at minimizing noise and interference over the 6.6-foot run. The Alitutumao cable uses oxygen-free copper and multi-strand cores for signal quality but does not list shielding. If hum pickup matters to you on a longer line-level run, the Ugreen design is the more protective of the two on paper.
You can connect it, but note that an electric guitar outputs a mono signal by design — it is not a stereo source. To run a stereo setup you need an amp in the chain, and when patching into a mixer you should use the stereo input/output port rather than a mono one.
