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 several pairs of headphones or speakers into one source and share the same audio with a whole row of people in an office, choose Cubilux Professional 5-Way; if you need to give a modern USB-C phone, tablet or laptop a working 3.5mm headphone jack, choose Ugreen 2.
These two products sit in the same aisle of the catalog but solve completely different problems. One is a passive analog splitter box. The other is an active digital-to-analog adapter. If you are equipping an office for shared listening, remote group sessions or multi-headphone monitoring, that difference decides everything.
• Cubilux Professional 5-Way — biggest strength: five 3.5mm female ports in a full aluminum housing, splitting one source's audio to up to five headphones or speakers at once, with no power supply needed.
• Cubilux Professional 5-Way — biggest trade-off: it is passive and analog, so it does not support microphones, cannot mix five inputs down into one, and you have to raise the source volume when several outputs are connected.
• Ugreen 2 — biggest strength: a 24bit/96kHz HiFi DAC in a braided USB-C to 3.5mm cable, with in-line control for volume and calls, sold as a two-pack.
• Ugreen 2 — biggest trade-off: it is a one-to-one adapter, not a hub — one USB-C port in, one 3.5mm jack out — so it cannot split audio across several listeners.
• Choose Cubilux Professional 5-Way if you are the person handing out headphones around a table.
• Choose Ugreen 2 if you are the person who just needs their own USB-C device to accept a normal wired headset.
This is a sharing tool, pure and simple. Cubilux takes a single 3.5mm auxiliary source — a phone, tablet, PC, laptop or computer — and fans it out to five separate 3.5mm ports. Nothing to install, no driver, no power adapter. The full aluminum alloy housing is there for a practical reason: it isolates electrical interference so the analog signal travels without static or ground noise creeping in. In an office where several devices sit close together on the same desk or in the same room, that shielding matters more than it sounds.
Who should skip it? Anyone who needs a microphone to work through it. It does not support mics, and it will not combine five sources into one output — the signal only flows one way, from source to listeners. It is also worth being clear about the passive design: with multiple outputs connected, each listener gets a share of the same signal, so you turn the source volume up to compensate. That is normal for a passive splitter, not a defect, but it is the kind of thing that surprises people who expect an amplified hub. And if your device has no 3.5mm jack at all, this is the wrong product for you — it is an analog accessory through and through.
Ugreen 2: Who It's For
Ugreen's adapter solves the opposite problem. Plenty of current phones, tablets and laptops dropped the headphone jack, which leaves people with perfectly good wired headsets they cannot plug in. This dongle puts a 3.5mm jack back on a USB-C device, and it does it with a real DAC chip rather than a bare pass-through. Ugreen quotes support for up to 24bit/96kHz — double the 16bit/48kHz that basic adapters typically handle — plus noise reduction circuitry. In practice that means cleaner, more detailed sound from a wired headset than a cheap throw-in adapter usually manages, and it is the kind of difference you notice with decent earphones or a car stereo.
The feature list that actually matters day to day is in-line control. Because it supports standard 3.5mm earphones with a mic, you can adjust volume and take calls without unlocking your phone. That single detail is what separates a usable adapter from an annoying one. Build quality is also pitched at daily carry: nylon braided cord, aluminum alloy shell to resist scratches and rust, slim enough to leave attached to a headset and forget about. It ships as a two-pack, which is sensible — one for the laptop bag, one for the car or desk drawer.
Compatibility is broad and clearly stated: USB-C iPhones, iPads, Galaxy S-series, Pixel models, OnePlus, MacBooks, Mac mini, iMac, PS5 and Switch 2. The item weight is around 16 grams and it needs no separate power. Who should skip it? Anyone hoping to connect several listeners at once, or anyone whose source device still has a working 3.5mm jack — in that case you simply do not need this. It is a one-in, one-out bridge, not a hub.
• Best for sharing audio with up to five people at once → Cubilux Professional 5-Way. Five ports, one source, no setup.
• Best for reviving the headphone jack on a USB-C phone, tablet or laptop → Ugreen 2. That is its entire job, and it does it with a 24bit/96kHz DAC.
• Best for a wired headset with a microphone and in-line controls → Ugreen 2. Cubilux explicitly does not pass microphone signals, so a headset mic will not work through it.
• Best for offices without power outlets at the desk → Cubilux Professional 5-Way. It is fully passive and needs no plug at all.
• Best for someone who wants a spare adapter in the bag → Ugreen 2. The two-pack means you can keep one at the desk and one in the car or backpack.
• Best for portable, toss-it-in-a-pocket gear → both, honestly. Cubilux is about the size of a small candy bar with a 6-inch cable; Ugreen's adapter is a short braided dongle weighing roughly 16 grams.
• Best for audio monitoring or group learning sessions → Cubilux Professional 5-Way. Multiple headphones, one feed, aluminum shielding against interference.
• Best for music, calls and movies on a modern phone → Ugreen 2. Volume and call control come from the adapter itself.
For an office, my pick is the Cubilux Professional 5-Way. A workspace usually needs one thing these adapters rarely provide: letting several people hear the same audio at the same time without buying new wireless hardware for everyone. Five ports, a metal body that cuts interference, zero power requirements and a footprint small enough to vanish in a drawer — that combination is hard to argue with, and for group learning or monitoring it is the more capable tool. I would still buy the Ugreen 2 alongside it, because the two are complements rather than rivals: Ugreen fixes a single USB-C device, Cubilux multiplies a single analog source. If your office is one person and one laptop with no headphone jack, buy Ugreen. If your office is a table full of people and one audio source, buy Cubilux.
No. Cubilux states the adapter does not support microphones. It is for headphones and speakers only, so use it with plain stereo listening gear rather than a headset you need to talk through.
It is the resolution the adapter's DAC can handle. Ugreen supports up to 24bit/96kHz where basic adapters are typically limited to 16bit/48kHz, which means it can carry more detail from a high-quality source to a good pair of wired earphones.
It can, yes. Because it is a passive design with no power supply, Cubilux advises turning the source volume up when several outputs are connected so each listener still gets a usable level.
Ugreen lists compatibility with USB-C phones, tablets, laptops, Macs, PS5 and Switch 2. A USB-C port on a hub usually behaves the same way as one on the device, though the adapter itself is a one-to-one connection, not a splitter.
