If you want a do-everything pair of everyday Bluetooth earbuds with a long-lasting charging case and an LED display that shows the battery at a glance, choose Aoslen Earbuds; if you need low-profile sleep earbuds built for side sleepers that stay put all night with a smart LED display on the case, choose Niecase Sleep Earbuds.
• Aoslen Earbuds — biggest strength: 42 hours of total playtime with a charging case and a case-mounted LED power display, plus Bluetooth 5.3, 13mm drivers, IPX7 water resistance and 4 ENC mics for calls.
• Aoslen Earbuds — biggest trade-off: It's a general-purpose in-ear bud, not a dedicated sleep design, so side sleepers who need a flat, low-pressure fit may find it bulky.
• Niecase Sleep Earbuds — biggest strength: A purpose-built sleep earbud that weighs under 10 grams for both buds, with a passive noise-isolating fit and a smart LED display that tracks the case and each earbud.
• Niecase Sleep Earbuds — biggest trade-off: Shorter single-charge battery life (about 7 hours) and no waterproofing rating in the specs, so it's not the pick for sweaty workouts or rainy runs.
• Who each is for: Aoslen Earbuds is for commuters, gym-goers and anyone who wants one pair for music, calls and workouts. Niecase Sleep Earbuds is for side sleepers and light sleepers who want something they can forget about overnight.
The Aoslen A68Pro is a general-purpose wireless earbud, and it's clearly built to cover as much ground as possible. The headline feature is battery: roughly 8 hours on a single charge, stretching to 42 hours with the compact charging case, and a 10-minute top-up that gets you about an hour of playback over USB-C. That combination matters in real life — a short charge before you leave the house genuinely rescues a dead pair.
The case also carries an LED power display, which shows the remaining charge in the case and the charging status of the buds. It's a small thing, but it removes the guessing game of "do I have enough battery for the commute home?" In my opinion, that's the most practical feature on this pair for most people.
So who should buy it? Anyone who wants one pair for the gym, the office, walking the dog and taking calls — especially if battery anxiety is your pet peeve. Who should skip it? Side sleepers. The 13mm driver and standard in-ear shape are tuned for output and fit variety, not for lying flat against a pillow all night. If you roll onto your side, this isn't the design for you.
Niecase Sleep Earbuds: Who It's For
The Niecase S25 is the opposite kind of product: it does one job, and it's designed around that job. It's a sleep earbud, and the specs show it. Both earbuds together weigh under 10 grams, which is remarkably light, and the low-profile shape is meant to sit flush enough that you can lie on your side without the bud digging into your ear.
The fit is the whole point here. Passive noise isolation blocks out disruptive sound without any active circuitry, the ergonomic shape is engineered to stay put when you toss and turn, and the brand positions it for side sleepers, flat sleepers and anyone who needs to sleep without ear pressure. If you've ever woken up because a normal earbud was pressing into your ear canal, that's the exact problem this design targets.
On the tech side, it runs Bluetooth 6.0 with up to 15 meters of range, and it also carries a smart LED display — the case shows real-time power levels for the case itself and for each earbud individually. Battery life is about 7 hours per charge, which is enough for a full night of sleep or a long workday. There's also a built-in high-sensitivity mic for hands-free calls, and a 2-year warranty is listed in the specs.
Who should buy it? Side sleepers, people who share a bed with a snorer, shift workers napping during the day, and anyone who wants background audio or white noise overnight without discomfort. Who should skip it? If you want one pair for running, gym sessions and rainy commutes, this isn't it — the specs list no waterproof rating, the design is optimized for sleep rather than sport, and the battery life is shorter than the Aoslen's case-backed total.
• Best for total battery life → Aoslen Earbuds. 42 hours with the case versus roughly 7 hours per charge on the Niecase.
• Best for side sleeping and overnight comfort → Niecase Sleep Earbuds. Under 10 grams for both buds and a low-profile, zero-pressure fit built for lying down.
• Best for workouts and bad weather → Aoslen Earbuds. The IPX7 rating is the deciding factor; the Niecase specs list no water resistance.
• Best for staying reachable while you sleep → Niecase Sleep Earbuds. The built-in high-sensitivity mic handles calls without you taking the buds out.
• Best for newer Bluetooth tech → Niecase Sleep Earbuds. It lists Bluetooth 6.0 with a 15-meter range, while Aoslen lists Bluetooth 5.3.
• Best for sound hardware and call mics → Aoslen Earbuds. A 13mm dynamic driver and 4 ENC mics are the more robust audio setup on paper.
• Best for quick top-ups → Aoslen Earbuds. A 10-minute charge is specified to deliver about an hour of playback.
• Best for a two-year safety net → Niecase Sleep Earbuds. A 2-year warranty is listed in its specs; the Aoslen sheet doesn't state a warranty term.
In my opinion, most people should buy the Aoslen Earbuds. The 42-hour case, IPX7 rating, 13mm drivers and four mics make it the more versatile pair — it handles workouts, calls, commuting and travel without asking you to change your habits.
I'd only steer you to the Niecase Sleep Earbuds if sleep is genuinely the job. If you're a side sleeper who has given up on earbuds at night, the sub-10-gram build and low-profile fit are the reason to pick it, and the smart LED display on the case is a nice bonus. Buy for the fit, not for all-day versatility.

FAQ
Yes. Wireless earbuds are consumer electronics — they contain Bluetooth radios, rechargeable batteries, drivers and control circuitry. Both the Aoslen A68Pro and the Niecase S25 fit that description, with Bluetooth 5.3 and Bluetooth 6.0 respectively.
can you connect earbuds to a tv
Often, yes — if your TV has Bluetooth audio output, you can pair either of these. The Aoslen lists broad compatibility with iOS, Android and smart devices, while the Niecase lists a 15-meter Bluetooth range. If your TV lacks Bluetooth, you'd need a separate transmitter.
should i get black or white earbuds
That's purely a preference call, but the two models differ here: the Aoslen A68Pro is listed in white, and the Niecase Sleep Earbuds are listed in black. White tends to show grime and scuffs; black hides wear better, which suits sleep earbuds you handle nightly.
how long do these earbuds last on a charge
The Aoslen gives about 8 hours per charge and up to 42 hours total with the case, with a 10-minute charge yielding roughly an hour of playback. The Niecase lists about 7 hours of average battery life per charge.
