If you want tiny, fully wireless earbuds you can hide completely and wear to bed or at work, choose Xmenha Smallest Invisible Earbuds; if you need a wired, USB-C sleep pair tuned for ASMR and snoring block that never needs charging, choose OFFBOX Sleep Earbuds USB-C.
• Xmenha's biggest strength: a genuinely invisible, featherweight fit — about 0.10 oz per earbud — with a charging case that stretches total listening to 20 hours.
• Xmenha's biggest trade-off: it relies on a battery, so you're tied to charging sessions (5 hours per earbud, 1.5 hours to refill) and a Bluetooth connection.
• OFFBOX's biggest strength: a wired USB-C design with braided cable and 32-bit decoding tuned for ASMR, white noise and audiobooks — no battery, no pairing, no charging.
• OFFBOX's biggest trade-off: it's a cable, so it's not invisible, and it only works with USB-C devices.
• Pick Xmenha if you want hidden, wireless earbuds for side sleeping, work or small ears.
• Pick OFFBOX if you want a dependable, plug-in sleep earphone for ASMR, travel and blocking snoring.
The Xmenha Smallest Invisible Earbuds are built around one idea: disappearing into your ear. Each earbud weighs roughly 0.10 oz, and the whole set comes in at about 1 ounce. The shape is rounded and miniaturized for small ears, which is exactly why side sleepers tend to reach for this style — there's very little shell to press against a pillow. In my opinion, that "sense-free" fit is the entire point of this product, and it's the reason it stands out from a standard pair of earbuds.
On the audio and call side, Xmenha combines physical noise isolation with acoustic noise cancelling and a microphone that's meant to keep your voice clear even in loud rooms. You get a 20Hz–20,000Hz dynamic driver, touch controls for play/pause, track skipping and answering calls, plus an LED power display on the case. Battery life is 5 hours per charge, and the metal charging case adds three more top-ups for a 20-hour total, with USB-C fast charging filling it in about 1.5 hours. Bluetooth 5 gives you roughly 15 meters of range, and the earbuds carry an IPX5 water-resistance rating.
Buy it if you want hidden earbuds for side sleeping, quiet music at work, or you simply have small ears that normal buds don't fit. Skip it if you hate managing battery levels, want a cable-free-only lifestyle anyway, or need a hardwired connection — that's not what this is.
The OFFBOX Sleep Earbuds take the opposite approach: instead of going wireless, they plug straight into a USB-C port and never ask you to think about charging. The housing is ultra-small and streamlined, paired with soft layered silicone tips that conform to the ear canal. That low-profile shape is designed specifically so lying on your side doesn't crush your ear, and the passive seal muffles snoring and ambient noise — the core reason people buy a sleep earphone in the first place.
Where OFFBOX leans hardest is audio tuning. It uses professional ASMR-specific tuning and a 32-bit digital decoding chip, wired through a twisted braided cable. That combo is aimed at ASMR audio, white noise, bedtime audiobooks and podcasts rather than booming bass. The braided, anti-break cord is built to survive tossing and turning without fraying or tangling, and there's a 3-button inline remote with an HD mic for calls, play/pause and track skipping. The standard USB-C plug fits Type-C phones, tablets and digital players. Color is black, and it carries a 2-year manufacturer warranty.
Buy it if you want a no-battery sleep earphone, you listen to ASMR or white noise to fall asleep, you travel a lot, or your phone only has USB-C. Skip it if you need true wireless freedom, want earbuds you can hide, or you own a device with a headphone jack instead of USB-C.

My Verdict
If I had to pick one, I'd go with the Xmenha Smallest Invisible Earbuds (B0BK7SLN4S). In my opinion, the combination of a genuinely invisible, ~0.10 oz fit, Bluetooth 5 wireless freedom, touch controls and a 20-hour charging case makes it the more flexible everyday pick — it works for side sleeping, quiet music at work and small ears alike. The OFFBOX is the smarter choice only if you specifically want a wired, no-battery ASMR earphone for USB-C devices. For most people torn between the two, Xmenha covers more situations.
Both are designed with side sleepers in mind. Xmenha uses an ultra-light ~0.10 oz shape to reduce pillow pressure, while OFFBOX uses a low-profile housing with soft layered silicone tips so lying flat on your side doesn't compress your ear.
Do I need to charge the OFFBOX Sleep Earbuds?
For ASMR specifically, the OFFBOX has the edge on paper. It's built with ASMR-exclusive tuning and a 32-bit digital decoding chip through a braided cable, which suits ASMR, white noise and audiobooks. Xmenha focuses more on an immersive stereo surround sound for general music and calls.
Only if your device has a USB-C port. OFFBOX uses a standard USB-C plug for Type-C smartphones, tablets and digital players. If your phone or player uses a different connection, Xmenha's Bluetooth 5 wireless link is the more compatible route.
