If you want a do-everything USB-C to 3.5mm adapter that turns any modern phone, tablet or laptop into a headphone-friendly device for flights, choose esbeecables USB C; if you need a replacement cable that lets you keep using your Bose or JBL 2.5mm headphones with a USB-C source, choose EARLA TEC USB C.
These two look similar in a search bar and completely different on your tray table. One is a bridge between USB-C and the 3.5mm jack your everyday earbuds already use. The other is a dedicated lifeline for a specific family of headphones — the ones with a 2.5mm socket built into the earcup. If you are packing for a long flight and want sports earbuds for flights that just work, the answer is the first one. If you own a pair of Bose QuietComfort cans and your new phone dropped the jack, the answer is the second.
• esbeecables USB C — biggest strength: a USB-C to 3.5mm female adapter with a built-in DAC chip, 96kHz/48-bit transmission, 40,000 samples per second, in-line mic and volume support, and a three-pack so you can leave one in each bag.
• esbeecables USB C — biggest trade-off: it is an adapter, not a cable for 2.5mm headphone sockets, and it explicitly does not support volume adjustment on Apple EarPods. You still supply your own 3.5mm headphones.
• EARLA TEC USB C — biggest strength: a 1.4m oxygen-free copper cable purpose-built for Bose QC25/QC35/QC35II/QC45/QC Ultra/NC700 and JBL 2.5mm headphones, with an in-line mic and volume control, and a soft tangle-free build.
• EARLA TEC USB C — biggest trade-off: it only fits 2.5mm-jack headphones. Plug it into ordinary 3.5mm earbuds and it does nothing for you.
• Who each pick is for: esbeecables if you want to connect the 3.5mm gear you already own to a USB-C phone; EARLA TEC if you own Bose or JBL 2.5mm headphones and want to keep using them.
This is the adapter for the person whose phone lost its headphone jack and who is not ready to give up wired audio. The design is simple: a short dongle with USB-C on one end and a 3.5mm female socket on the other. Plug it in, plug your headphones in, and you are done — no drivers, no apps, no setup. The built-in Smart DAC chip does the conversion, and the spec sheet claims 96kHz/48-bit transmission at 40,000 samples per second to keep bass deep and highs clean.
Who should buy it: anyone who wants to use standard 3.5mm headphones, earbuds or even a seat-back-friendly pair of wired buds with a USB-C device, and anyone who likes having spares. It ships as a three-pack in white, which is genuinely useful — one in your carry-on, one at your desk, one in the car.
Who should skip it: if your headphones use a 2.5mm jack, this adapter will not fit them. And if you rely on Apple EarPods specifically, note that volume adjustment through those is not supported, so plan on controlling volume from the device itself.
EARLA TEC USB C: Who It's For
This is a different tool entirely. EARLA TEC's cable is a replacement aux cord for headphones that use a 2.5mm connection at the earcup — think Bose QuietComfort QC25, QC35, QC35II, QC45, QC Ultra and NC700, plus OE2, OE2i, SoundLink and SoundTrue, and JBL E45BT, E55BT, E50, E35 and E30. If that list describes your headphones, you already know the problem: the original cable is lost, frayed, or terminated in a plug that no longer matches your phone.
The build is what sells it. Oxygen-free copper core for low signal loss and anti-oxidation, wrapped in a TPE bendable memory cord that resists kinks and tangles, in a soft grey finish. Length is around 1.4m — long enough to reach from a phone in a jacket pocket or a seat-back pouch without a mess of slack. There is an in-line microphone and a volume control button, so you can answer and hang up calls, adjust volume, and skip tracks without touching the phone. The manufacturer positions it exactly where I would: an everyday cable for commuting, work calls, gaming and travel, and a backup cable to keep in the headphone case for flights and hotels.
Who should buy it: owners of Bose or JBL 2.5mm headphones who want to keep using them with a USB-C phone, tablet or MacBook. It covers iPhone 15 through 17e, iPad Pro/Air/Mini with USB-C, MacBook, Samsung Galaxy S9 through S26 plus Note and Z Fold/Z Flip, and Google Pixel.
Side-by-Side: Which Should You Choose?
• Best for using the 3.5mm headphones you already own → esbeecables USB C. The female 3.5mm socket accepts virtually any standard wired headphone, earbud or aux device.
• Best for Bose or JBL 2.5mm headphones → EARLA TEC USB C. It is built specifically for that connector family and nothing else will do the job.
• Best for flights and hotels → both, but differently. EARLA TEC is described as a backup cable for flights and hotel use; esbeecables is the one that lets a seat-back-style 3.5mm pair work with a USB-C phone.
• Best for call quality → esbeecables USB C. Clear Voice Noise Reduction is engineered to filter ambient noise, and wire control is supported for mic, volume and play/pause.
• Best for cable length and feel → EARLA TEC USB C. Roughly 1.4m of tangle-free memory cord with an in-line remote; esbeecables is a short dongle, which is the point.
• Best for having spares → esbeecables USB C. It comes as a three-pack, so losing one is not a crisis.
• Best for durability claims → esbeecables USB C. Strain relief rated for 15,000+ bending tests, shielded enamel wire and metal-coated connectors.
• Best for gaming and longer sessions → EARLA TEC USB C. A proper 1.4m cable gives you room to move; a dongle plus your own cable is more clutter.
For most people heading to an airport, I would buy the esbeecables USB C adapter. It is the more flexible purchase: three units, a DAC chip, wide USB-C compatibility, call-friendly noise reduction, and it lets you use whatever 3.5mm headphones or clip-on earbuds you already trust for a flight. The EARLA TEC cable is excellent at its one job, and if you own Bose QuietComfort or JBL 2.5mm headphones, it is the right call — no adapter will substitute for it. But as a general "make my wired audio work again" purchase for flights and daily use, the esbeecables three-pack wins my vote. Check the current price on Amazon before you commit, since these are very different products at very different value points.
how to use wired headphones without headphone jack
You need a converter that puts a 3.5mm socket back on your device. The esbeecables USB C adapter plugs into your phone's USB-C port and accepts standard 3.5mm headphones, with no drivers or apps required — plug in and listen. If your headphones use a 2.5mm jack instead, the EARLA TEC USB C cable is the correct part.
how do i connect my wired headphones to my phone
Check the plug on your headphone cable first. A 3.5mm plug goes into the esbeecables USB C to 3.5mm adapter, which then goes into your phone. A 2.5mm plug on Bose QC or JBL headphones calls for the EARLA TEC USB C to 2.5mm cable, which plugs directly into a USB-C device. Both support in-line mic and volume control on compatible gear.
how to make aux cable with headphones
You do not have to make anything — you adapt. The esbeecables dongle turns a USB-C port into a 3.5mm aux output so your existing headphone cable becomes your aux cable. The EARLA TEC cable does the same job for 2.5mm headphones, replacing the original cord with a 1.4m oxygen-free copper one that has an in-line remote.
Both are travel-oriented, in different ways. EARLA TEC is explicitly pitched as a backup cable for flights, hotels and daily use, and its 1.4m tangle-free cord suits a seat-back pouch. esbeecables is the better travel pick if you want to use standard 3.5mm sports earbuds or the best clip on earbuds for flights with a USB-C phone, and the three-pack means a spare for every bag.
