How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a sleep-focused earbud with a touchscreen case, longer total playtime and a proper sleep mode, choose ZYHKON Sleep Earbuds; if you need the smallest, lightest hidden earbuds with an LED battery display and independent single-bud use, choose Lunvaxo Mini Invisible Headphones.
• ZYHKON Sleep Earbuds — biggest strength: A full-color LED touchscreen charging case that controls playback, volume, calls, sleep mode, language, wallpaper and brightness, backed by up to 48 hours of total playtime and Bluetooth 5.4.
• ZYHKON Sleep Earbuds — biggest trade-off: At 3.0 grams per earbud it is the heavier of the two, and its feature set is more about the case and app-like screen than about being the absolute smallest bud in your ear.
• Lunvaxo Mini Invisible Headphones — biggest strength: Genuinely tiny and light at roughly 0.07 oz (2 g) per earbud with a compact round case, plus an LED display that shows left and right battery levels separately and earbuds that each pair independently.
• Lunvaxo Mini Invisible Headphones — biggest trade-off: It leans on passive noise isolation and a smaller 6 mm driver, and the advertised playback is 4–6 hours per charge with over 30 hours total from the case — far less than ZYHKON's 48-hour claim.
• Pick ZYHKON if you want the sleep mode, the touchscreen case and long between-charge endurance.
• Pick Lunvaxo if you want the most discreet fit possible, per-bud battery readouts and the freedom to wear just one earbud.
The ZYHKON Sleep Earbuds are built around one idea: making bedtime easier. Each earbud weighs 3.0 grams and uses a polished, ear-fitting shape so it sits flush enough to stay comfortable when you roll onto your side. The headline feature is the sleep mode, which silences the low-battery and shutdown voice prompts so nothing beeps you awake at 3 a.m. That single detail is the reason I'd point a restless sleeper here first.
The charging case is the other half of the story. It has a full-color LED touchscreen you can use to play or pause, change volume, skip tracks and answer calls, and it also handles sleep mode activation, seven language options, wallpaper and brightness. In practice that means you can adjust things without hunting for your phone in the dark. Sound comes from 13 mm dynamic drivers with a chamber design that balances air pressure, reduces leakage and keeps clarity up in noisy rooms, and you get five EQ modes — Standard, Classic, Jazz, Rock and Pop.
Battery is where ZYHKON pulls ahead. Up to 48 hours of total playtime, with USB-C fast charging that fills the case in about 1.5 hours, and instant connection the moment you open the lid. Bluetooth 5.4 handles pairing and stability.
Who should buy it: side sleepers who want the alarms killed, people who like fiddling with EQ and settings, and anyone who hates charging constantly. Who should skip it: if you specifically want the lightest possible bud or you'd rather control everything from your phone than from a screen on the case, the Lunvaxo is the more natural fit. Also worth knowing — ZYHKON's own guidance is to check your battery level before you fall asleep, so a quick pre-bed glance is part of the routine.
The Lunvaxo Mini Invisible Headphones take the opposite approach: disappear. Each earbud is about 0.07 oz — roughly 2 grams — in a compact in-ear shape, which is about as close to invisible as an earbud gets. The sell here is that you forget you're wearing them, whether you're side sleeping, lying on a pillow or wearing them through a long work session.
The round charging case uses a built-in LED display that shows left and right earbud battery levels individually, which is genuinely useful when one bud drains faster than the other. Full charge takes about 1.5 hours, a single charge runs 4–6 hours, and the case carries you past 30 hours of total playback. Bluetooth 5.4 gives you a 33-foot range and — importantly — each earbud can be paired and used independently, so you can wear just one and leave the other in the case.
Audio is handled by a 6 mm dynamic driver with a faster response and larger amplitude than you'd expect at this size; Lunvaxo describes natural highs and vigorous lows. Noise control is passive isolation, not active cancellation, so it blocks sound by sealing your ear rather than by electronics. Touch controls manage music and calls, and the built-in microphone keeps hands-free calls clear on compatible phones. Pairing is simple: take them out, open Bluetooth settings, select "SK26."
Who should buy it: small-eared users, light sleepers who want the least intrusive fit, people who take calls with one earbud in, and commuters or office workers who want something hidden. Who should skip it: if you want a screen on the case, EQ presets, a dedicated sleep mode that kills prompts, or marathon battery life, ZYHKON covers those better.

I'd buy the ZYHKON Sleep Earbuds. In my opinion the sleep mode alone justifies it for anyone who's been woken by a battery warning, and the combination of a touchscreen case, 13 mm drivers, five EQ modes and up to 48 hours of playtime makes it the more complete product for night after night of use. The Lunvaxo is the better pick if sheer smallness and single-bud flexibility matter more to you than endurance and on-case controls — but for most side sleepers, ZYHKON is the one I'd reach for.
Both are designed for side sleeping. ZYHKON uses a 3.0 g polished ear-fitting shape and a sleep mode that silences alerts; Lunvaxo is lighter at about 0.07 oz per bud. If you want the absolute lightest feel, go Lunvaxo; if you want silence from prompts, go ZYHKON.
ZYHKON advertises up to 48 hours of total playtime with a 1.5-hour USB-C charge. Lunvaxo lists 4–6 hours per single charge and over 30 hours total from the case, also charging in about 1.5 hours.
Neither uses active noise cancellation. ZYHKON reduces leakage through its chamber design and claims better clarity in noisy environments; Lunvaxo relies on passive noise isolation from the in-ear seal. Both block sound mainly by fitting your ear well.
The Lunvaxo Mini Invisible Headphones — each earbud pairs and works independently, so you can leave the other in the case. ZYHKON doesn't list independent single-bud pairing among its features.
