How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want to plug a single TRRS gaming headset into a PC or laptop that still has separate headphone and mic jacks, choose UGREEN Headphone Splitter; if you need to bridge the gap between 3.5mm and 6.35mm gear like amps, mixers and studio headphones, choose MOBOREST 3.5mm.
• UGREEN Headphone Splitter — biggest strength: it splits one 4-pole TRRS headset jack into two separate 3.5mm TRS plugs, so a headset with a built-in mic can feed a PC's dedicated headphone-out and mic-in ports at the same time.
• UGREEN Headphone Splitter — biggest trade-off: it only solves one problem. It is a directional TRS-male-to-TRRS-female adapter, not a general-purpose converter, and it is aimed squarely at legacy dual-jack computers.
• MOBOREST 3.5mm — biggest strength: a two-pack that covers both directions of the 3.5mm-to-6.35mm conversion, so you get the male-to-female and female-to-male versions in one set.
• MOBOREST 3.5mm — biggest trade-off: it does nothing for microphone separation, and it is not built for the PC headset scenario at all — it is a stereo adapter for amps, mixers and home audio.
• Who UGREEN is for: gamers and desktop users with an older PC, laptop or console controller that has separate audio and mic jacks.
• Who MOBOREST is for: musicians, students and home-studio tinkerers connecting 3.5mm headphones or phones to 1/4-inch equipment, and vice versa.
This is a problem-solver, not a gadget. The core job is narrow and specific: take a headset that ends in a single 4-position TRRS plug — the kind with both audio and microphone on one connector — and break it into two standard 3.5mm TRS plugs. One goes to the headphone output, one goes to the microphone input. That is the whole point, and it matters because a lot of PCs and laptops, especially ones built before roughly 2010, never adopted a single combined jack. They kept the older dual-jack layout, and a modern headset simply will not work with them without a splitter like this.
The build details back up the everyday use. UGREEN uses oxygen-free copper conductors with triple shielding to keep interference and signal loss down, which is exactly what you want when a mic line runs right next to a headphone line. The nylon-braided jacket and aluminum alloy casing are there for durability — this is a small adapter that lives plugged into a desktop or gets tossed in a laptop bag, so the strain relief and scratch resistance matter more than they sound. The 24K gold-plated contacts are a corrosion play for the long haul.
So who should buy it? Anyone with a gaming headset and a PC, laptop or console controller that has separate audio and mic ports. UGREEN lists a wide range of compatible headsets, including HyperX Cloud 2, Razer Kraken, Astro A10, Sennheiser HD 598 Cs, Logitech UE 6000 and Turtle Beach models, plus Switch and PlayStation/Xbox controllers. If that describes your setup, this is the right tool.
Who should skip it? If your computer already has a single combined headset jack, you do not need this — you would be adding a conversion you do not require. And if your goal is connecting headphones to a guitar amp or a mixer, this adapter does not do that at all. It is a microphone-and-headphone splitter, full stop.
MOBOREST is solving a completely different mismatch. Its job is converting between the 3.5mm (1/8-inch) plug used on most headphones and phones and the 6.35mm (1/4-inch) jack found on amplifiers, mixers, home theater gear and pro audio equipment. The clever part is that the set ships with both directions: one 3.5mm male to 1/4-inch female adapter, and one 3.5mm female to 1/4-inch male adapter. So whether your headphones are too small to fit the big jack or your instrument cable is too big for your phone, one of the two covers it.
The materials are chosen for that mixed environment. High-purity copper cores and 24K gold-plated contacts resist corrosion and interference, which is the practical answer to static and distortion creeping into a signal. The one-piece solid brass shell is the standout detail — plastic adapters tend to crack when they get squashed in a gig bag, and brass does not. Both adapters use standard TRS stereo pin configuration, so they work with headphones, earphones, electric guitars, basses, smartphones, laptops, amps and mixers.
Two small touches show the design intent. The bright red finish is there so you can actually find these things in a drawer full of black cables — a real annoyance when you are setting up before a set. And the 360-degree textured grip treads let you pull an adapter out of a tight jack with one hand, which matters more than it sounds when you are mid-soundcheck.
Side-by-Side: Which Should You Choose?
• Best for a gaming headset with a built-in mic on a PC → UGREEN Headphone Splitter. It is the only one of the two that separates audio and microphone.
• Best for connecting headphones to a guitar amp, mixer or receiver → MOBOREST 3.5mm. That is its entire purpose.
• Best for coverage in one purchase → MOBOREST 3.5mm. The two-pack gives you both conversion directions, so you are not caught out.
• Best for older dual-jack laptops and desktops → UGREEN Headphone Splitter. This is the exact scenario it was designed around.
• Best for portability and abuse → MOBOREST 3.5mm. The solid brass shell is built to survive a gear bag.
• Best cable-quality focus → UGREEN Headphone Splitter. Oxygen-free copper, triple shielding and a nylon-braided jacket are all about keeping a clean signal over a cable run.
• Best for musicians and students on the move → MOBOREST 3.5mm. Brass build, red visibility and a spare adapter make it the travel-friendly pick.
• Best if you are unsure what you need → check your jacks first. A single combined headset port points to neither; two separate ports point to UGREEN, and a 1/4-inch jack points to MOBOREST.
In my opinion, these two are not really competitors — they solve different problems, so the honest answer is to pick based on your jack. If you have a headset with a mic and a PC with separate audio and mic ports, I would buy the UGREEN Headphone Splitter; that is the one scenario where it is genuinely the only correct choice here. If you are moving between 3.5mm consumer gear and 1/4-inch pro audio, I would buy the MOBOREST 3.5mm set instead, because the two-direction pack and brass build make it the more versatile tool. Buy for the jack you actually own, not the one you might own someday.
No. Despite the name, it does not send one source to two headphones. It splits a single TRRS headset plug into separate headphone and microphone plugs for a PC with dual jacks.
No, and that is not its job. Both adapters in the set are standard TRS stereo, so they carry audio only — they cannot separate a microphone signal.
The MOBOREST set does, in both directions, thanks to the two included adapters. The UGREEN adapter stays within 3.5mm — it converts a TRRS headset plug to two TRS plugs.
Both are small, inexpensive accessories, and the site's "Check latest price on Amazon" button will show you the current cost. Compare that against how many scenarios each covers before you decide.
