How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a wired earpiece that keeps a low profile and works with basically any phone that still has a round headphone socket, choose XFOX Universal 3.5mm; if you need a USB-C set of in-ear earbuds with a built-in mic for video calls on a modern Samsung Galaxy, choose VIFIGEN Samsung USB C. Those two sentences already tell you the split: the XFOX is an old-school 3.5mm acoustic-tube earpiece built for covert, low-profile listening, while the VIFIGEN is a current USB-C wired earphone aimed at Galaxy and other USB-C phones. For video calls, the connector on your phone decides this for you.
• XFOX Universal 3.5mm — biggest strength: a transparent acoustic air tube and a throat mic you can tuck under a collar, so the earpiece stays nearly invisible and the sound stays away from your head.
• XFOX Universal 3.5mm — biggest trade-off: it is a 3.5mm wired earpiece with a uniaural (single-ear) design, so it is not aimed at stereo music or at phones that dropped the headphone jack.
• VIFIGEN Samsung USB C — biggest strength: a USB-C wired connection with a built-in mic and HiFi stereo sound tuned for Galaxy phones, tablets and other USB-C devices.
• VIFIGEN Samsung USB C — biggest trade-off: USB-C only — it will not fit a phone or laptop that only has a 3.5mm jack, and it is a conventional in-ear earbud rather than a hidden one.
• Who XFOX is for: anyone on a 3.5mm phone who wants a discreet, low-profile earpiece for calls, security work or noisy rooms.
• Who VIFIGEN is for: anyone on a USB-C Samsung Galaxy (or another USB-C phone) who wants a straightforward wired earphone with a mic for calls, workouts and study.
The XFOX Universal 3.5mm is not really a music earphone — it is a communications earpiece. Its whole design revolves around two ideas. First, an acoustic air tube carries sound from a hidden micro-speaker up to your ear, which is how it keeps the phone's radiation away from your head. Second, that tube is transparent, so from a few feet away it is barely noticeable. The mic is hidden in the centre of the push-to-talk switch, and there is a throat mic option you can hide under a collar. If you have ever wanted an earpiece that does not look like an earpiece, this is the point of it.
The controls are practical for one-hand use: answer/off, music, volume and a universal switch, with voice control listed as the control type. It is wired over a standard 3.5mm jack, so it fits just about any phone or device that still has that round socket — iPhone 6 and earlier, older Galaxy Notes and S-series, plus HTC, Moto, Huawei, ZTE, LG and Xiaomi handsets. The driver is a dynamic driver with a 20 Hz – 20,000 Hz range, and the noise control is sound isolation rather than active cancellation. It ships with three soft earbud tips and a user manual.
Who should buy it? People who want an in-ear earpiece for video calls and voice work on a 3.5mm device, and especially anyone in security, events, bars, restaurants, hotels or warehouses where a discreet earpiece matters more than hi-fi sound. Who should skip it? If your phone is USB-C only, this simply will not plug in. And if you want proper stereo music or active noise cancelling earbuds for video calls, this is not that product — it is a single-ear, low-profile talk piece.
The VIFIGEN Samsung USB C is the modern counterpart: a wired USB-C earphone with a built-in microphone, made for hands-free calls while you are working out, driving, gaming or studying. It uses a dynamic driver with the same 20 Hz – 20,000 Hz range as the XFOX, but here the pitch is HiFi stereo sound delivered over a copper wire plus a DAC chip — which is exactly what you need when a phone has no headphone jack and the audio has to come out of the USB-C port digitally.
Compatibility is the headline. The listing covers a long list of USB-C Samsung Galaxy models — S25 Ultra, S25, S25+, S24 FE, S24 series, S23 series, S22 series, S21 series, S20 series, Note 20 and Note 10, plus A-series phones like the A16 5G, A56, A36, A26, A15 5G, A54, A55, A35, A25 and more — and it also lists Z Fold and Z Flip models. It goes beyond Samsung too: recent iPhone 15/16/17-class USB-C models, iPad Pro, iPad Air and iPad mini, and a wide spread of Google Pixel phones. If you are shopping for earbuds for a Galaxy and your phone has a USB-C port, that list is the reason this one keeps coming up.
Side-by-Side: Which Should You Choose?
• Best for a modern Samsung Galaxy → VIFIGEN Samsung USB C. It is built around the USB-C port your Galaxy actually has.
• Best for an older 3.5mm phone → XFOX Universal 3.5mm. The round jack is the whole reason this earpiece exists.
• Best for discreet, low-profile calls → XFOX Universal 3.5mm. Transparent tube, hidden mic, throat mic under the collar.
• Best for stereo music and media → VIFIGEN Samsung USB C. It is a stereo pair; the XFOX is uniaural.
• Best for hands-free calls while driving or working out → VIFIGEN Samsung USB C. Built-in mic plus a cable clamp for the cord.
• Best for noisy venues, security and events work → XFOX Universal 3.5mm. That is the environment it was designed around.
• Best for cross-device flexibility → VIFIGEN Samsung USB C. Galaxy, Pixel, iPad and USB-C iPhone are all covered.
• Best if you hate visible wires and earpieces → XFOX Universal 3.5mm. The transparent tube is the selling point.
In my opinion, most people reading this in 2026 should buy the VIFIGEN Samsung USB C. If you own a Galaxy or any USB-C phone, it plugs straight in, gives you a mic, stereo sound and a cable clamp, and it is the more natural choice for video calls and everyday listening. I would only pick the XFOX Universal 3.5mm if you are still on a 3.5mm device or you specifically need a hidden, low-profile earpiece for security-style work. For video calls on a current phone, the VIFIGEN is the one I would reach for. Check the current price on Amazon before you commit, since that is the one thing that can still tip the decision.
It depends on your port, not on sound quality. The VIFIGEN connects over USB-C and gives you a stereo pair with a built-in mic, which suits video calls on a modern Galaxy. The XFOX is a 3.5mm single-ear earpiece with a hidden mic, better for discreet calls on an older phone.
It is listed for a very wide set of USB-C Galaxy models, from S20 and Note 10 up through S25 Ultra, plus A-series phones like the A16 5G, A36 and A56, and Z Fold and Z Flip. If your Galaxy charges over USB-C, it is on the list.
No — not without an adapter. It is a wired earpiece with a 3.5mm jack, so it needs a phone or device with that round socket. On a USB-C-only phone, the VIFIGEN is the one that fits.
No. Both list sound isolation as their noise control, which means they physically block some outside noise rather than cancelling it electronically. The XFOX leans on its in-ear fit and tube design, and the VIFIGEN on the earbud seal.
