How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want the pair that stays put in tiny ears and tells you exactly how much charge is left, choose Yeforu Invisible; if you need the flatter, side-sleeper-first design in a skin-tone finish, choose Xmenha Extra.
• Yeforu Invisible — biggest strength: a complete, predictable package: 2.3 g buds, Bluetooth 5.4, a stated 4–5 hours per charge stretching to 24 hours with the case, USB-C fast charging, and an LED case display that reads out battery level from 1% to 100%.
• Yeforu Invisible — biggest trade-off: the buds sit in the ear canal with silicone tips, so side sleepers who hate any pressure inside the ear may feel them more than a flat, non-inserting design.
• Xmenha Extra — biggest strength: an ultra-thin, flat design explicitly built so side sleepers don't get squeezed, plus a 10 mm diaphragm driver, auto-pairing, a waterproof rating and a compact pocket-friendly case.
• Xmenha Extra — biggest trade-off: the spec sheet is thinner on hard numbers — no stated battery hours, no stated weight in grams, and no charging-time figure — so you're buying on design intent and sound claims rather than measurable endurance.
• Pick Yeforu Invisible if you want small-but-conventional in-ear buds with clear battery numbers and a charging case you can read at a glance.
• Pick Xmenha Extra if you sleep on your side, want a flat bud that doesn't push into the canal, and value the waterproof rating and skin-tone look.
The Yeforu Invisible is the more "complete product" of the two on paper. Each bud weighs 2.3 g, which is genuinely light — light enough that the design intent of "almost unnoticeable, wear all day without pressure" is at least plausible rather than marketing noise. It's an in-ear design with silicone earbuds, plastic housing in black, touch controls, and 32 ohm impedance, so it behaves like a normal pair of true wireless buds that happens to be built small.
Buy it if you want tiny, discreet in-ear buds with a clear battery story: office work, study sessions, calls, and wearing them for long stretches. Skip it if you're a committed side sleeper who can't tolerate anything sitting in the ear canal, or if you need a waterproof rating — none is listed for Yeforu, so don't assume sweat or rain protection.
Xmenha Extra: Who It's For
The Xmenha Extra attacks the same problem from a different angle: instead of shrinking an in-ear bud, it flattens it. The headline claim is that you can sleep on your side without squeezing your ears, because the design "does not enter the ear." That's a meaningful distinction. A lot of people who'd love to sleep with audio simply can't, because a silicone tip pressing into the canal gets uncomfortable within minutes when your head is on a pillow. A flat, non-inserting bud sidesteps that entirely — that's the entire reason this category exists, and Xmenha leans into it hardest.
Beyond the flat shape, you get a 10 mm diaphragm driver with what's described as triple-frequency equalization, marketed as stereo HIFI with a "whale cavity" surround effect. Take the naming with a grain of salt, but a 10 mm driver is a real, reasonable size for this form factor. Auto-pairing is genuinely convenient: open the case and the buds boot and reconnect to the last device, and they power down and charge when you drop them back in. The case is described as compact and sleek enough to live in a pocket.
Two practical details stand out. First, a waterproof rating — relevant for workouts, sweaty commutes, and general clumsiness. Second, the color is nude, which matters more than it sounds: if the whole point is invisibility, a skin-tone bud hides better than black against most ears. Weight is given as 0.1 oz, roughly 2.8 g, and the brand lists an age range of 1–99 and describes the look as doubling as "a small decoration on your ears."
Side-by-Side: Which Should You Choose?
• Best for side sleeping → Xmenha Extra. The flat, non-inserting design is purpose-built for pillow pressure. Yeforu is in-ear, so it inserts.
• Best for battery transparency → Yeforu Invisible. A stated 4–5 hours per charge, 24 hours total with the case, 1–2 hour charging, plus a 1%–100% LED readout.
• Best for workouts and sweat → Xmenha Extra. It carries a waterproof rating; Yeforu lists none.
• Best for discreet, invisible look → Xmenha Extra, on the strength of the nude colorway alone. Yeforu is black.
• Best for lighter buds on paper → Yeforu Invisible at 2.3 g versus roughly 2.8 g — a small edge, but if every gram matters in a tiny ear, it counts.
• Best for sound-spec detail → Xmenha Extra, with its 10 mm diaphragm driver and stereo/HIFI claims; Yeforu gives impedance (32 ohm) but no driver size.
• Best for call clarity in noise → a tie on paper. Both claim noise suppression for calls, and neither publishes a measurement.
• Best for pairing convenience → Xmenha Extra, which explicitly auto-pairs and auto-charges from the case.
In my opinion, Xmenha Extra is the better buy for the specific job these buds exist to do. The whole reason to buy an invisible sleep bud is to wear it lying on your side, and Xmenha is the one whose design is built around not entering the ear canal — plus you get waterproofing, a 10 mm driver, and a skin-tone finish that actually disappears. I'd pick Yeforu Invisible instead if you want a conventional in-ear fit with silicone tips and you care about knowing your exact battery percentage; its LED case and stated 24-hour total are real, useful advantages. But if sleep comfort is the deciding factor, Xmenha wins.
Xmenha Extra, in my view. Its flat design is explicitly made not to enter the ear, which is the main source of pressure when you lie on your side. Yeforu Invisible uses silicone in-ear tips, so it inserts further into the canal.
Yeforu states 4–5 hours of playback per charge and 24 hours total with the case, with a 1–2 hour USB-C charge. Xmenha doesn't publish playback or charging times, so if battery certainty matters to you, Yeforu gives you more to work with.
Yes — Xmenha lists a waterproof rating, which makes them the better pick for workouts and sweaty commutes. Yeforu Invisible has no water-resistance rating listed, so treat it as dry-use only.

On features alone, Xmenha Extra gives you waterproofing and a flat side-sleeper design, while Yeforu Invisible gives you a 24-hour battery claim and an LED charge display. Value depends on which of those you'd actually use.
