How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want the cleaner, more focused listening tool with stronger active noise cancellation and a screen that tells you exactly how much power is left, choose AOC Earbuds; if you need a smart touchscreen case that doubles as a tiny control hub for your phone's camera, music and even a flashlight, choose NANSLS Earbuds.
• AOC Earbuds — biggest strength: A 4-mic hybrid active noise cancellation system rated to cut up to -42dB of ambient sound, paired with 10mm dynamic drivers and a dual EQ (Music / Bass Boost) switch. That's a serious spec sheet for quiet-focused listening.
• AOC Earbuds — biggest trade-off: The charging case is a straightforward LED percentage display, not a touchscreen. If you want on-case controls beyond what the earbuds' touch panels give you, this isn't that product.
• NANSLS Earbuds — biggest strength: A smart touchscreen charging case that handles music, volume, calls, EQ modes, wallpapers, a timer, a flashlight, a camera remote and a find-earbuds function — genuinely unusual for in-ear buds.
• NANSLS Earbuds — biggest trade-off: It uses ENC (environmental noise cancellation for calls) rather than the deep hybrid ANC of the AOC set. Its focus is clear voice pickup and case convenience, not maximum silence.
• Who each pick is for: AOC suits commuters, flyers and anyone who wants to block out noise and just listen. NANSLS suits tinkerers, travelers and people who hate pulling out their phone for every small task.
The AOC Earbuds (model ACT2525) are built around one clear idea: shut the world out and play music well. The headline feature is a 4-microphone hybrid active noise cancellation system rated to eliminate up to -42dB of ambient noise. In plain terms, that's the kind of spec you'd want on a noisy flight, a crowded open-plan office, or a train platform. The brand positions it for exactly those scenarios, and the hardware backs the claim.
The audio side is equally deliberate. You get 10mm dynamic drivers with high-grade magnets, an impedance rating of 140 ohm, and a dual EQ switch that flips between a balanced "Music Mode" and a punchier "Bass Mode" — no companion app required. For someone who alternates between focused desk work and a hard workout, that physical toggle is genuinely convenient. Battery life is rated at up to 9 hours per charge, extended to 45 hours total with the 500mAh case, and a full recharge takes about 1.5 hours. The case supports wireless charging and shows a real-time percentage readout on its LED display, so you're never guessing.
Comfort details matter here too: three sizes of silicone tips (S/M/L), an ergonomic in-ear shape, touch controls, and Bluetooth with a rated range of about 10.1 meters. The set is finished in Carbon Black with a black case, both plastic.
Who should buy it: frequent flyers, commuters, office workers in loud spaces, and runners who want strong passive isolation from a secure tip seal plus active cancellation on top.
Who should skip it: anyone whose main wish is a gadget-forward case with a screen, or who wants IPX7-level water resistance for heavy sweat and rain. The AOC sheet doesn't list an IP rating, so I wouldn't assume one.
The NANSLS Earbuds (model T20) take a totally different angle. The centerpiece isn't the drivers — it's the charging case. That case carries a smart touchscreen that lets you control music, volume, calls and EQ modes, set wallpapers, run a timer, fire up a flashlight, use it as a camera remote, and trigger a find-earbuds function. That last one is the kind of thing people don't appreciate until an earbud vanishes under a couch cushion.
On the audio side, NANSLS leans on ENC microphones — environmental noise cancellation aimed at call clarity rather than deep listening silence — plus dynamic drivers for stereo sound and bass. Bluetooth 5.4 handles pairing and reconnection, and the brand lists compatibility with iPhone, Android, iPad, tablets and laptops. Battery is rated at 6–9 hours per charge and up to 48 hours with the case, with a 1.5-hour charge time over Type-C. For context, the official product information lists 6 hours average life and 35 ohm impedance.
Two practical wins stand out. First, IPX7 waterproofing: that's a real rating, and it means sweat and light rain aren't a problem. Second, the whole package is light — 1.76 ounces total, with a case around 2.5 x 2.5 x 1.5 inches. The controls are touch-based with active noise cancellation listed, and Bluetooth range is rated at 33 feet, noticeably wider on paper than the AOC's roughly 10 meters.
Who should buy it: gym-goers, runners in wet weather, commuters who take a lot of calls, and anyone who genuinely enjoys a gadget with extra tricks built in.
Who should skip it: listeners who prioritize maximum noise blocking or a bass-forward, high-impedance driver setup. ENC is a call-clarity tool, not a match for hybrid ANC.
• Best for active noise cancellation → AOC Earbuds. A 4-mic hybrid system rated to -42dB is a deeper silence spec than NANSLS's ENC call-focused approach.
• Best for battery life → NANSLS Earbuds. Up to 48 hours total with the case versus 45 hours on the AOC set — close, but NANSLS edges it on the headline number.
• Best for single-charge stamina → AOC Earbuds. Up to 9 hours per charge against NANSLS's 6–9 hour range, with the AOC sheet claiming 30% longer than standard earphones.
• Best for water and sweat resistance → NANSLS Earbuds. IPX7 is a concrete rating; the AOC sheet lists none.
• Best for sound tuning without an app → AOC Earbuds. The dual EQ switch (Music / Bass Boost) is a physical toggle, plus 10mm drivers at 140 ohm impedance.
• Best for case features → NANSLS Earbuds. Touchscreen control, wallpapers, timer, flashlight, camera remote and find-earbuds are all on the case.
• Best for wireless charging → AOC Earbuds. The case supports wireless charging; NANSLS specifies Type-C.
• Best for lighter carry → NANSLS Earbuds. 1.76 ounces total is very light, and the case is compact at roughly 2.5 inches square.
In my opinion, I'd buy the AOC Earbuds. The reason is simple: earbuds live or die by how well they let you hear your music and escape your surroundings, and the AOC set attacks both with a -42dB hybrid ANC system, 10mm dynamic drivers, a dual EQ switch and up to 9 hours per charge. The LED percentage display on the case is a small but genuinely useful touch, and wireless charging keeps the routine frictionless. The NANSLS case is clever — I won't pretend it isn't — but clever case tricks don't fix a listening experience built around call clarity rather than deep quiet. If you're choosing between the two, buy AOC for the ears, NANSLS for the extras.
Based on the specs, yes. AOC lists a 4-mic hybrid ANC system rated to cut up to -42dB of ambient noise. NANSLS lists ENC microphones, which are aimed at making your voice clearer on calls rather than silencing the room around you.
Yes — the case itself carries a smart touchscreen for music, volume, calls, EQ modes, wallpapers, a timer, a flashlight, a camera remote and a find-earbuds function. It's the standout feature and the main reason to pick NANSLS over AOC.
AOC lists up to 9 hours per charge with a 45-hour total including the case. NANSLS lists 6–9 hours per charge and up to 48 hours total. Per charge they're close, with AOC claiming the longer single-charge figure; over the full case, NANSLS slightly leads.
The NANSLS Earbuds list an IPX7 waterproof rating, which covers sweat and light rain. The AOC Earbuds don't list an IP rating, though they do include three tip sizes (S/M/L) for a secure fit during movement. For wet-weather workouts, NANSLS is the safer spec-based pick. Whichever you lean toward, check the current price on Amazon before deciding — that's the one number this comparison can't give you.
