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 two pairs of wired headphones into one USB-C phone or tablet so two people can watch the same movie on a flight, choose ZOOAUX PRO USB C; if you need a replacement aux cord that brings a pair of Bose or JBL 2.5mm headphones back to life — with an inline mic for calls — choose EARLA TEC USB C.
• ZOOAUX PRO USB C, biggest strength: a true 1-in-2-out splitter with a built-in DAC chip, so two people hear the same clean stereo audio from one USB-C port.
• ZOOAUX PRO USB C, biggest trade-off: it's a listening-only adapter — no microphone support, no volume buttons, no charging pass-through, and it needs a TRS headphone rather than a TRRS one.
• EARLA TEC USB C, biggest strength: it's a direct replacement cable for 2.5mm-jack headphones (Bose QuietComfort, JBL and similar), with an inline mic and volume control for calls and playback.
• EARLA TEC USB C, biggest trade-off: it feeds exactly one headphone, and the 2.5mm end only fits the specific headphone families it lists.
• Pick ZOOAUX PRO USB C if you want to share audio between two listeners from a single USB-C device.
• Pick EARLA TEC USB C if you own 2.5mm headphones that need a working cable with a mic.
This is a sharing tool first and foremost. The ZOOAUX PRO USB C takes one USB-C port and turns it into two 3.5mm outputs — a 1-in-2-out audio splitter. Plug it into an iPhone 15/16/17, a Galaxy S23 through S26, an iPad Pro/Air/Mini, a Pixel, a MacBook or most USB-C laptops, and two people can listen to the same thing at once. No drivers, no setup. For a long flight, a road trip, or helping two kids follow the same lesson on one tablet, that's the whole point of the design. Note that the headphones you connect need a TRS plug — a TRRS plug (the kind with a mic contact) isn't supported.
The part I like on paper is the built-in DAC chip. Cheap passive splitters tend to drop volume and add hiss when you split a signal in two; a dedicated DAC feeding both outputs is the design choice meant to avoid that, keeping stereo sound stable on both ends. The housing is aluminum alloy with reinforced strain relief at the connectors, and the cable jacket is nylon-braided to resist tangling. ZOOAUX PRO also states the connectors passed a 25,000+ plug/unplug durability test, which speaks to repeated daily use. There's a warranty listed too — the listing text is inconsistent, showing both 24-month and 18-month wording, so I'd treat that as "there is a warranty" and confirm the term on the product page.
Who should skip it: anyone who wants to make phone calls through their wired headset. The ZOOAUX PRO does not support microphone function — no mic, no volume control, no charging. It's purely for listening, and it won't work with a Nintendo Switch.
The EARLA TEC USB C solves a much narrower but very real problem: your headphone cable died, and the headphones didn't. It's a USB-C to 2.5mm aux cable built for 2.5mm-jack headphones — Bose QuietComfort QC25, QC35, QC35II, QC45, QC Ultra, NC700, OE2/OE2i, SoundLink and Soundtrue, plus JBL E45BT, E55BT, E50, E35 and E30. If you own one of those, this is the cable that lets you keep using them with a modern USB-C phone, tablet or laptop instead of buying new headphones.
Unlike the ZOOAUX PRO, this one carries a microphone. There's an inline mic and a volume control button for hands-free calls, play/pause and volume adjustment on compatible devices. The description also mentions track skipping and answering/hanging up calls, so it's aiming to be your everyday headset cable rather than a listening-only adapter. The cord is oxygen-free copper with a TPE memory-wire jacket — stretch-resistant, tangle-free and about 1.4m long, which is a sensible length for pocket-to-headphone use and easy to stash as a backup in a headphone case. It's a single-headphone cable, so there's no splitting here.
Who should skip it: anyone hoping to connect two listeners, or anyone with standard 3.5mm headphones — the 2.5mm end simply won't fit those. It's also not a charging cable.
• Best for sharing audio with a second person → ZOOAUX PRO USB C. It's the only one of the two with two outputs.
• Best for reviving Bose or JBL 2.5mm headphones → EARLA TEC USB C. The 2.5mm plug is made for exactly those models.
• Best for phone calls and inline controls → EARLA TEC USB C. Inline mic plus volume button; the ZOOAUX PRO supports neither.
• Best for sound quality on a split signal → ZOOAUX PRO USB C. The built-in DAC chip is designed to hold volume and clarity across both outputs.
• Best for a single listener with 3.5mm headphones → ZOOAUX PRO USB C, as long as those headphones use a TRS plug and you don't need a mic.
• Best for travel and commuting → EARLA TEC USB C if you're one person on a call or listening solo; ZOOAUX PRO USB C if you're travelling as a pair.
• Best for durability under constant plugging → ZOOAUX PRO USB C. Braided nylon, aluminum housing and the stated 25,000+ cycle test.
• Best for a lightweight backup cable in a headphone case → EARLA TEC USB C. 1.4m, memory-wire, tangle-free.
If I had to pick one, I'd buy the ZOOAUX PRO USB C — but only if sharing audio is actually your problem. Two outputs, a DAC chip and a braided, aluminum-reinforced build make it the more versatile adapter for flights, road trips and tablet use with a partner or kids. That said, if your situation is "my Bose cable broke and I want calls back on my USB-C phone," the EARLA TEC USB C is the smarter buy and the ZOOAUX PRO can't do that job at all. Match the tool to the job, and check the current price on Amazon before you commit.
how to make aux cable with headphones
You don't build one — you buy an adapter or replacement cable that ends in the right plug. For 3.5mm headphones on a USB-C phone, the ZOOAUX PRO USB C converts USB-C to two 3.5mm outputs. For 2.5mm headphones like Bose QuietComfort, the EARLA TEC USB C is the direct replacement cord.
how to use wired headphones without headphone jack
Use a USB-C to aux adapter. The ZOOAUX PRO USB C plugs into your USB-C port and gives you 3.5mm outputs for TRS headphones — no drivers needed. The EARLA TEC USB C does the same for 2.5mm-jack headphones and adds an inline mic and volume control. Neither one charges your device.
how do i connect my wired headphones to my phone
Check your headphone plug first. A 3.5mm TRS plug pairs with the ZOOAUX PRO USB C on USB-C phones, tablets and laptops. A 2.5mm plug — typical of Bose QC and JBL models — pairs with the EARLA TEC USB C. Plug in, press play, and the adapter handles the conversion.
Only the EARLA TEC USB C does. It has an inline mic and volume button for calls and playback control. The ZOOAUX PRO USB C explicitly does not support microphone function, volume control or charging — it's a listening-only splitter.
