If you want the smallest, most discreet earbuds with the longest total playtime for sleep, work and all-day wear, choose Xmenha Smallest Invisible Earbuds; if you need a lighter-feeling pair with newer Bluetooth, a battery readout on the case and voice-assistant controls, choose Yihou Ear Buds Invisible.
• Xmenha's biggest strength: a truly tiny in-ear shape that hides from the front, plus a long 6–7 hour single-charge playtime and up to 35 hours with the case.
• Xmenha's biggest trade-off: the control scheme is a single-key design (long-press to power, tap to play/pause, double-tap to skip), which is less flexible than dedicated touch buttons.
• Yihou's biggest strength: a genuinely featherweight build — around 0.08 oz per earbud — with Bluetooth 5.3 and a case that shows the remaining battery.
• Yihou's biggest trade-off: shorter endurance, at roughly 4 hours per charge and 20 hours with the case, so you'll top up more often.
• Pick Xmenha if total battery life and a proven low-latency connection matter most to you for sleep or long shifts.
• Pick Yihou if you want the lightest possible feel, the newest Bluetooth version and on-case battery visibility.
The Xmenha Smallest Invisible Earbuds are built around a single idea: disappear in your ear. The design is deliberately mini, and the front-facing profile is the selling point — from straight on, they're barely there. That matters for anyone who wants audio in a meeting, a lecture or a shared office without a visible gadget hanging off their head. The earpiece is an in-ear shape with a sound-isolation approach rather than active noise cancellation, so the seal does the work of blocking background chatter.
Where Xmenha pulls ahead is endurance. The specs list 6–7 hours of playtime on a single charge, about 1.5 hours to recharge, and up to 35 hours total with the charging case. That's a real difference if you wear earbuds through a full workday or leave one in overnight. The Bluetooth 5.1 chip is described as low-latency and stable, with a connection range up to roughly 33 feet, and it plays nicely with iOS, Android and Windows. Pairing is simple — the buds link to each other as soon as you lift them out of the case, then you tap "X21" in your phone's Bluetooth menu.
The audio side uses a dynamic driver with a graphene diaphragm, covering a 20 Hz–20,000 Hz range, with the manufacturer emphasizing high-frequency clarity. Controls are one-key: long-press for power, single tap for play/pause, double tap for the next track, and one tap to answer or end a call. Who should buy it? Sleepers, side-sleepers, office workers, students and anyone who wants a discreet earbud that lasts. Who should skip it? If you want granular volume control from the bud itself or a battery readout on the case, this isn't the one — and note it's listed as an adult product.
Yihou takes the opposite route: make it as light as physically possible. Each earbud weighs about 0.08 oz, and the brand compares the size to a peanut — small enough that they're described as completely invisible from the front. For people with narrow ear canals or anyone who finds normal earbuds fatiguing after an hour, that low weight is the whole argument. Yihou specifically points at office workers as the ideal user, since nothing about these draws attention.
The tech is newer here. Yihou uses Bluetooth 5.3, the most recent version in this comparison, with a range of about 30 feet. Battery life is the trade-off: roughly 4 hours per charge, about 1 hour to charge, and up to 20 hours total with the case. That's shorter than Xmenha, but Yihou counters with a genuinely useful feature — the charging case stands on its own like a tumbler and displays the remaining battery capacity, so you always know where you stand instead of guessing.
Controls are where Yihou is clearly more generous. The touch system supports separate buttons for answering and rejecting calls, muting your voice, raising and lowering volume, play/pause, and even announcing who's calling. There's a microphone, and Siri voice assistant is supported. The age range is listed as 15+, and there's no warranty listed. Who should buy it? Anyone who wants the lightest possible fit, wants volume control on the bud, or wants to see battery status at a glance. Who should skip it? Heavy all-day users and overnight sleepers who don't want to recharge every few hours.
• Best for total battery life → Xmenha Smallest Invisible Earbuds. Up to 35 hours with the case versus roughly 20 hours on Yihou.
• Best for long single sessions → Xmenha Smallest Invisible Earbuds. 6–7 hours per charge means you can get through a full shift or a night's sleep.
• Best for the lightest feel → Yihou Ear Buds Invisible. Around 0.08 oz per bud is about as light as in-ear audio gets.
• Best for the newest connection tech → Yihou Ear Buds Invisible. Bluetooth 5.3 beats Xmenha's 5.1 on paper.
• Best for control flexibility → Yihou Ear Buds Invisible. Volume, mute, call reject and caller announcement beat a single-key scheme.
• Best for knowing your battery level → Yihou Ear Buds Invisible. The case shows capacity; Xmenha's case doesn't.
• Best for discreet sleep and work wear → Xmenha Smallest Invisible Earbuds. The front-on invisibility and long runtime suit overnight and all-day use.
• Best for young or first-time users → Yihou Ear Buds Invisible. Its 15+ rating and simple touch controls are easier to hand over.
In my opinion, the Xmenha Smallest Invisible Earbuds are the better buy for most people searching this comparison. The reason is simple: the specs solve the two problems that actually annoy discreet-earbud owners — running out of power mid-day and needing to recharge constantly. Six to seven hours per charge and up to 35 hours with the case is a meaningful cushion over Yihou's 4 and 20 hours. Yihou wins on weight, Bluetooth version and controls, and if you want the lightest possible bud with a visible battery readout, that's a legitimate reason to pick it. But if you want one pair to sleep in, work in and forget about, I'd take the Xmenha. Check the current price on Amazon before deciding, since pricing shifts over time.
Both are described as mini and front-invisible. Yihou gives a concrete figure — around 0.08 oz per bud, peanut-sized — while Xmenha emphasizes a very light, barely-there in-ear fit. On published weight, Yihou is the lighter of the two.
Per the specs, yes — about 4 hours of listening per charge, extending to roughly 20 hours with the charging case. Xmenha lists 6–7 hours per charge and up to 35 hours with its case.
On Yihou, yes — the touch controls include volume up and down, plus mute and call reject. Xmenha uses a single-key layout focused on power, play/pause, track skip and call answer/end.
I'd point to the Xmenha for sleep, because the longer 6–7 hour runtime and sound-isolation fit suit overnight wear better. Yihou's lighter weight is comfortable, but its 4-hour battery means a recharge partway through the night.
