If you want to plug five pairs of headphones into one source and share the same music with a group, choose Cubilux Professional 5-Way; if you need to flip between two audio sources or two playback devices with a button press, choose WLTASUY 3.5mm.
• Cubilux Professional 5-Way — biggest strength: five 3.5mm outputs from a single source, so a whole group can listen to the same thing at once, with a full aluminum housing that isolates electrical interference.
• Cubilux Professional 5-Way — biggest trade-off: it's a passive splitter, so it can't support microphones, can't mix five inputs down into one, and you'll need to raise the volume when several outputs are connected.
• WLTASUY 3.5mm — biggest strength: one-button switching between two devices in either direction (two sources into one output, or one source out to two outputs), no cable swapping required, and it includes an audio cable.
• WLTASUY 3.5mm — biggest trade-off: it only handles two ports, so it's the wrong tool if your goal is getting a crowd listening at the same time.
• Who each is for: the Cubilux is for group listening and multi-headphone setups; the WLTASUY is for desk setups where you're tired of reaching behind the PC to move a plug.
The Cubilux Professional 5-Way is a five-port 3.5mm AUX splitter. One input goes in, five stereo outputs come out, and everyone plugged in hears the same audio. The housing is full aluminum alloy, which the spec sheet ties directly to isolating electrical interference and keeping the signal clean — no static, no ground noise, in the manufacturer's framing. It's black with a metallic finish, and it measures just 3.1 x 0.8 x 0.4 inches, so it disappears into a pocket or a bag.
This is the pick for anyone running a shared listening session. Language learners doing remote group study, a family watching a movie on a laptop with five sets of earphones, a teacher or trainer monitoring several listeners off one device — that's the natural fit. It's plug-and-play across phones, tablets, PCs, laptops and desktops, with no extra power supply and no plug type to worry about. The included cable is 6 inches, which keeps the whole thing tidy on a desk or in a travel bag.
WLTASUY 3.5mm: Who It's For
The WLTASUY 3.5mm is a bidirectional audio switcher built around a manual selector button. It works in both directions: send two sources into one output (2x1), or send one source out to two playback devices (1x2). You press the button to choose which one is active. That single detail is the entire point — no unplugging and re-plugging cables behind your desk, no fumbling for the right jack.
It's aimed at a very specific annoyance: too many 3.5mm devices and not enough patience. Picture a PC, a phone, a game console or a Blu-ray player on one side, and a soundbar, speaker or headphone on the other. The WLTASUY sits in the middle and lets you pick. Input sources listed include Android phones, MP3/MP4 players, PCs, game consoles, laptops and Blu-ray players; outputs include speakers, soundbars and headphones. It needs no external power, and it ships with a 1-meter (3.3-foot) audio cable, so you can set it up the day it arrives.
The box itself is compact at 2.6 x 2.5 x 1.1 inches with a solid aluminum shell — textured and durable in the brand's description — so it sits on a desk without eating space. Audio output mode is stereo. There's also a 90-day warranty description, which is worth knowing before you buy.
Who should skip it? Anyone who needs more than two ports, or who wants several people listening simultaneously. Two is the ceiling here. If your scenario is "five headphones, one movie," go the other way.
Side-by-Side: Which Should You Choose?
• Best for group listening → Cubilux Professional 5-Way. Five outputs from one source is exactly what it's built for.
• Best for switching between two devices → WLTASUY 3.5mm. The selector button does the job a cable swap would otherwise do.
• Best for multi-headphone monitoring or study sessions → Cubilux Professional 5-Way. The 6-inch cable and 3.1-inch body keep it portable.
• Best for microphone use → neither. Cubilux states plainly that its splitter doesn't support mics, and the WLTASUY is an audio switch, not a mic interface.
• Best for cable-free operation → tie. Both are passive and need no external power.
• Best for build feel → tie, with a nod to Cubilux. Both use aluminum, but Cubilux's full alloy housing is specifically pitched at interference isolation.
• Best for a tidy travel kit → Cubilux Professional 5-Way. It's the smaller of the two at 0.8 inches tall versus the WLTASUY's 1.1-inch box.
• Best for someone who hates reaching behind the TV → WLTASUY 3.5mm. One click beats unplugging.
In my opinion, most people searching this comparison are trying to solve a sharing problem, not a switching problem — and that points to the Cubilux Professional 5-Way. Five ports, aluminum isolation, and a genuinely pocketable footprint make it the more useful object to own, and the passive design is a fair trade once you know to turn the volume up. I'd pick the WLTASUY 3.5mm only if your setup is strictly two devices and the button press is the whole point. Check the current price on Amazon before you commit, since that's what usually settles a close call.
The Cubilux, clearly. It splits one source into five 3.5mm outputs so up to five people can listen at once. The WLTASUY maxes out at two ports and is designed for selecting between devices, not for group listening.
Can I use either one with a microphone?
No. It's plug-and-play with no external power required, and it comes with a 1-meter (3.3-foot) audio cable in the box. The Cubilux is also passive and needs no power supply.
Because it's a passive splitter with no built-in amplification. The manufacturer notes that when connecting a couple of outputs you should turn the volume up accordingly to reach the level you want.
The WLTASUY 3.5mm, in my opinion. With two sources and one output — or one source and two outputs — the one-button switching is the exact feature you need, and the included cable means no extra purchase to get started.
