How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want one cable that covers the widest range of output jacks — Lightning phones, USB-C phones, and anything with a plain 3.5mm socket — choose Tanzoizoi 3in1USB; if you need microphone support and in-line control for calls, gaming and video meetings, choose Ugreen USB C.
• Tanzoizoi 3in1USB — biggest strength: a true three-in-one design (Lightning, USB-C and 3.5mm-to-3.5mm) in one cable, so one accessory covers phones, tablets, laptops and MP3 players.
• Tanzoizoi 3in1USB — biggest trade-off: the three connectors cannot be used at the same time, and the ABS plastic shell with a TPE jacket is a less premium build than an aluminum housing.
• Ugreen USB C — biggest strength: a proper USB-C-to-3.5mm cord with a HiFi DAC chip (up to 24-bit/96kHz) that also carries mic audio and in-line control, which matters for calls and gaming headsets.
• Ugreen USB C — biggest trade-off: it is not bidirectional and does nothing for Lightning phones or for devices that already have a 3.5mm jack — it is strictly USB-C out to a 3.5mm in.
• Who each pick is for: Tanzoizoi for households juggling several connector types; Ugreen for anyone living in USB-C land who needs a microphone on the other end.
The Tanzoizoi 3in1USB is built around one idea: you should not need three different cables. Its three connector paths cover an iPhone or iPad through the Lightning end, a USB-C phone, tablet or laptop through the Type-C end, and any device with a 3.5mm female jack — a computer, an MP3 player, an older phone — through the plain 3.5mm-to-3.5mm path. The result is a single cable that can move between your car's AUX input, a home speaker, and a pair of wired headphones without you digging through a drawer. It is plug and play, with no app required.
Under the jacket, Tanzoizoi uses a Realtek DAC chip rated for up to 24-bit/96kHz, plus a 2.9mm tinned copper core. The 3.94-foot length is the practical detail I keep coming back to — it is long enough to reach from a phone in a cradle or a pocket to a car stereo AUX port, or from a laptop across a desk to a speaker, without pulling tight. The TPE jacket is described as tangle-free and anti-stretch, and the round white ABS shell keeps it visually neutral.
Ugreen USB C: Who It's For
Ugreen USB C is a focused tool. It takes audio from a Type-C phone, tablet or laptop and sends it out through a 3.5mm plug to a car stereo, speaker, headphone or sound card. The headline feature is the advanced DAC chip supporting up to 24-bit/96kHz, and Ugreen frames the decoding as stable and clean — which is the whole point of going digital out of the phone rather than relying on whatever the phone's internal path happens to be. It is plug and play, no app, no setup.
The feature that actually separates it from the Tanzoizoi is microphone and in-line control support. Because it works with TRRS (L/R/GND/MIC) as well as TRS (L/R/GND) interfaces, it can carry a headset mic, which makes it genuinely useful for game playing, video calls and streaming interaction — not just music playback. The physical build gets more attention too: an aluminum alloy shell, metal plug, and an anti-bending tail that Ugreen says has been tested past 15,000 bends, plus multi-shielding for stable transmission. It weighs about 0.05 kg and is compact enough to leave on a keyring or in a bag pocket.
Who should buy it: USB-C users who take calls or game with a wired headset, and anyone who wants a durable, metal-bodied cable for daily car duty. Who should skip it: iPhone users on Lightning, anyone with a 3.5mm-only phone, and anyone hoping to charge while listening — there is no charging or video capability. Note the direction too: it is not bidirectional, so it cannot take a 3.5mm phone output into a USB-C headset, and it will not work with AirPods Max.
Side-by-Side: Which Should You Choose?
• Best for mixed device households → Tanzoizoi 3in1USB. Lightning, USB-C and 3.5mm-to-3.5mm in one cable covers more people with less clutter.
• Best for iPhone users on Lightning → Tanzoizoi 3in1USB. Ugreen's cable is USB-C only and will not fit a Lightning port.
• Best for durability in a car or bag → Ugreen USB C. Aluminum alloy shell, metal plug and a bend-tested anti-bending tail are a more rugged combination than an ABS plastic shell.
• Best for long reach → Tanzoizoi 3in1USB. At 3.94 feet it is noticeably longer than Ugreen's 3.3 feet, which helps in a car with a distant AUX port.
• Best for audio quality claims → Ugreen USB C, on paper. Both list 24-bit/96kHz DAC capability, so neither has a clear advantage there; Ugreen adds multi-shielding, Tanzoizoi leans on its Realtek chip and tinned copper core.
• Best for plug-and-forget simplicity → Ugreen USB C. One USB-C end, one 3.5mm end, one direction — nothing to think about.
• Best for flexibility across jacks → Tanzoizoi 3in1USB, as long as you accept that its three connectors are used one at a time.
In my opinion, most people should buy the Ugreen USB C. If your phone, tablet or laptop is USB-C — which is nearly everything now — the Ugreen does the core job better: it carries your headset microphone, it feels sturdier in the hand thanks to the aluminum shell and reinforced tail, and it does exactly one thing with no ambiguity. I would only steer you to the Tanzoizoi 3in1USB if you specifically need Lightning support or you want a single cable that also handles a 3.5mm-to-3.5mm connection for an older device. That flexibility is real, but it comes with a plastic build and no mic support. Work out which of those two gaps you can live with, then check the current price on Amazon before you commit.
FAQ
Yes. Ugreen states it supports headset microphone function and in-line control, and it works with TRRS and TRS audio devices. Just note that the maximum sample rate depends on the input and output devices you connect, and it does not work with AirPods Max.
Yes — that is the point of the design. It has a Lightning connection for iPhone and iPad, a USB-C connection for Android phones, tablets and laptops, and a 3.5mm-to-3.5mm path for anything with a standard headphone jack. Only one connector works at a time.
No. Neither cable carries power — Ugreen explicitly states there is no charging capability and no video transfer, and Tanzoizoi's cable is an audio-only design. Both are for audio transmission only, so plan on charging separately.
