How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a complete pair of wired kids' headphones with a microphone, SharePort sharing and a volume limit, choose LilGadgets Connect+ Pro; if you need four USB-C to 3.5 mm adapters so you can keep using wired headphones on a phone that has no headphone jack, choose Fidioto 4.
• LilGadgets Connect+ Pro — biggest strength: a full over-ear wired headset built for children, with a 4-foot nylon braided cable, in-line mic, 93 dB volume limiting and SharePort so two headsets can run off one device.
• LilGadgets Connect+ Pro — biggest trade-off: it is a 3.5 mm headphone, so it still needs a jack somewhere — a phone that dropped the port will not work with it directly.
• Fidioto 4 — biggest strength: four USB-C to 3.5 mm adapters with a built-in DAC chip, tiny 12.5 cm cables that turn a port-less phone back into a headphone-friendly device.
• Fidioto 4 — biggest trade-off: it is an adapter, not a headphone — no drivers, no earcups, and no support for OMTP/TRS microphones or mic-only devices.
• Pick LilGadgets Connect+ Pro if you are buying headphones for a child aged 6 and up who uses a tablet, Chromebook or anything with a 3.5 mm jack.
• Pick Fidioto 4 if you already own wired headphones and your phone, tablet or laptop only has USB-C.
The Connect+ Pro is a wired over-ear headset aimed at children aged 6 and up. That framing shows up in the design: 40 mm dynamic drivers, a frequency response of 20 Hz to 20 kHz and 32 ohms impedance — easy specs for a phone, tablet or laptop to drive without any amplifier. More importantly for parents, the output is volume limited to 93 dB. That is the single most useful line on the whole spec sheet if your kid wears headphones for schoolwork, long car rides or flights.
Build quality is where this one punches above the usual kids' headphone. The frame is high-quality polycarbonate reinforced with stainless steel extenders for variable sizing, covered in SoftTouch fabric padding, and it folds for storage. The cable is 4 feet of nylon braid with an in-line microphone — long enough to reach across a desk, short enough not to tangle into a knot every time it goes in a backpack. There is a microfiber travel pouch in the box, and the cable is detachable, which is a genuinely practical detail: the cable is usually the first thing to fail on any wired headphone.
Who should buy it: parents buying a first real headset for a school-age kid, especially if siblings share a tablet or a screen. Who should skip it: anyone shopping for an adult, anyone who wants wireless audio, and anyone whose only device is a modern phone with no headphone jack — the headphone itself does not solve that problem.
Fidioto 4: Who It's For
The Fidioto 4 is a completely different kind of product, and it is worth being blunt about that: this is not a headphone. It is a four-pack of USB-C to 3.5 mm female adapters for people who already own wired headphones and whose devices no longer have a headphone jack. The connector is USB-C on one end, 3.5 mm female on the other, and the whole cable is 12.5 cm long and about 3.6 g.
The technical core is the DAC chip inside. It supports up to 16-bit / 48 kHz audio sampling and converts the digital signal from a USB-C port into the analog signal a headphone needs. That is the reason an adapter like this exists at all — a passive plug cannot do that job. Fidioto also specifies a CTIA-compatible 3.5 mm female port and high-quality enamelled copper wire to keep cable impedance low. Two limitations are stated plainly on the spec sheet and matter a lot: OMTP/TRS microphones are not supported, and mic-only devices are not supported. Apple EarPods with a 3.5 mm plug will not have their volume buttons work through this adapter.
Durability looks sensible for the category: an off-white braided cable in a white ABS housing, rated to withstand 15,000 flex tests. That rating targets the exact failure point of cheap dongles, which is where the cable meets the plug. Compatibility covers most modern USB-C phones and tablets — iPhone 16/17 family and iPad Pro, Samsung Galaxy S24 through S20, Huawei Mate and P series, Google Pixel 2/3/4 XL, OnePlus 6T/7/7 Pro, and Xperia XZ2. It is plug and play, with no drivers or software, and Fidioto lists a one-year warranty.
Who should buy it: anyone with a good pair of wired headphones and a USB-C phone, tablet or laptop with no audio jack — and the four-pack means you can leave one in a bag, one at a desk and one in a car. Who should skip it: anyone who needs actual headphones, anyone using an OMTP-wired headset, and anyone who wants a mic-only accessory to work through it.
• Best for young children → LilGadgets Connect+ Pro. Volume limiting to 93 dB, over-ear SoftTouch padding and a foldable frame built for kids 6+.
• Best for sharing one screen → LilGadgets Connect+ Pro. SharePort links a second headphone to the same device with no splitter.
• Best for port-less phones → Fidioto 4. This is the whole point of the product: a USB-C to 3.5 mm adapter with a DAC chip.
• Best for travel and school bags → Fidioto 4. A 12.5 cm, 3.6 g braided cable disappears into a pocket, and you get four of them.
• Best for calls → depends. The Connect+ Pro has an in-line microphone built into its cable, while the Fidioto adapter passes through listening, remote and calls but explicitly does not support OMTP/TRS mics or mic-only devices.
• Best for durability where it matters → both, in different places. LilGadgets uses polycarbonate plus stainless steel extenders and a detachable braided cable; Fidioto uses a braided cable and ABS housing rated to 15,000 flex tests.
• Best for a household with mixed devices → Fidioto 4. Four adapters cover several phones and tablets at once, so a wired headset you already own keeps working everywhere.
In my opinion these two products should not be treated as rivals at all, because they solve different halves of the same problem. If a child needs headphones — real earcups, a volume limit, a mic for class calls and a way to share audio with a sibling — I would buy the LilGadgets Connect+ Pro (ASIN B07Y2G745C). Its spec sheet reads like it was written by someone who has watched a kid destroy a headphone cable; the steel extenders, foldable frame and detachable braided cord are the details I would pay for.
I would only choose the Fidioto 4 if you already own wired headphones you like and your phone has no jack. In that case, four DAC-equipped adapters is the more useful purchase, and the CTIA compatibility note is the one thing to check against your headset before buying. If budget is your deciding factor, check the current price on Amazon for both — the numbers move, and the page button will show you today's.
how to make aux cable with headphones
You do not build one — you use what you already have. A headphone with a 3.5 mm plug is the aux cable: the LilGadgets Connect+ Pro has a fixed 4-foot braided cable ending in a 3.5 mm jack, and the Fidioto 4 turns a USB-C port into a 3.5 mm female socket so a standard headphone cable can plug in.
how to use wired headphones without headphone jack
Use a USB-C to 3.5 mm adapter with a built-in DAC, like the Fidioto 4. It converts the digital audio from the USB-C port into an analog signal the headphone can play, supports up to 16-bit / 48 kHz, and needs no drivers or software. Just plug the adapter into the phone and the headphone into the adapter.
how do i connect my wired headphones to my phone
If your phone has a 3.5 mm jack, plug the headphone straight in — that is exactly what the LilGadgets Connect+ Pro is designed for. If it only has USB-C, plug a Fidioto 4 adapter into the phone and the headphone into the adapter's 3.5 mm female port; it is plug and play with no setup.
does the Fidioto 4 work with any headphone microphone
Not with every one. The 3.5 mm female port is CTIA compatible, but OMTP/TRS microphones and microphone-only devices are not supported, and the volume controls on Apple EarPods with a 3.5 mm plug will not work through it. Check your headset's wiring standard before you buy.
