How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a sport earbud that doubles as a genuinely reliable headset for zoom calls, choose Rulefiss Earbuds Sport; if you need maximum battery life plus a built-in flashlight in a palm-sized case, choose MINISO MS120. That's the short version. The longer version is about earhooks, microphones, and how each one behaves when you actually live with it.
• Rulefiss Earbuds Sport — biggest strength: Four microphones with ENC noise reduction and a 56-hour total battery figure, wrapped in a flexible earhook design built for movement.
• Rulefiss Earbuds Sport — biggest trade-off: The earhook fit is not for everyone, and it's an in-ear sport bud rather than something you'd grab purely for style.
• MINISO MS120 — biggest strength: Bluetooth 6.0, 70 hours of total playtime, and a three-level flashlight built into the charging case.
• MINISO MS120 — biggest trade-off: IPX5 water resistance and a single 8-hour battery figure per charge mean it's more of a commuter and travel bud than a heavy-sweat training partner.
• Who Rulefiss is for: Anyone who wants one pair for workouts, running, and clear voice pickup on laptop calls.
• Who MINISO is for: Anyone who wants long listening sessions, easy pocket carry, and a case that does something extra when the lights go out.
The Rulefiss Earbuds Sport is a sport-first design that doesn't treat voice as an afterthought. It runs Bluetooth 5.4 with dual-channel transmission, and the spec sheet claims roughly double the transmission speed and noticeably better stability than 5.3, plus a 41ms low-latency figure. For a buyer, that translates into a connection that holds up when you walk away from your laptop mid-meeting instead of crackling or dropping.
Audio hardware is a 14.2mm composite diaphragm dynamic driver with AAC/SBC decoding. The claimed frequency range stretches from 18Hz to 25kHz. In my opinion, that larger driver is the reason the bass feels present without swallowing vocals — useful when you're listening to a podcast or a conference call rather than a bass-heavy track.
Comfort and durability are where the sport DNA shows. Each bud weighs about 8g, uses a 45° flexible earhook, and ships with silicone tips in three sizes. IP-X7 waterproofing is the highest rating in this comparison, so sweat and rain are covered. Battery life is 6–8 hours per charge, stretched to 56 hours with the 800mAh case, with a percentage LED display and a 1.5-hour USB-C charge.
Who should skip it? If you dislike earhooks, or you want a bud you can pop in and out instantly without seating it properly, the hook design will annoy you. It's also explicitly not compatible with gaming devices, so don't buy it for a console.
MINISO MS120: Who It's For
The MINISO MS120 goes after a different buyer entirely: someone who wants a lightweight, pocketable bud that lasts an absurdly long time and offers a genuinely unusual extra. The headline feature is the three-level flashlight built into the charging case. It sounds like a gimmick until you think about a dark parking lot, a power cut, or a camping trip — then it's the kind of thing you're glad exists.
Battery is the other big story. MINISO lists 7–8 hours per charge and 70 hours total with the case, backed by an LED digital display that shows remaining power the moment you open the lid. That's the longest total figure between these two, and the display takes the guesswork out of it.
Connectivity runs Bluetooth 6.0, which the sheet describes as offering faster pairing, a more stable connection, and lower latency than 5.3/5.4. Audio is a dynamic driver covering 20Hz–20kHz, tuned toward deep bass and clear vocals for music, podcasts, movies, and hands-free calls across iPhone, Android, and Samsung devices.
Build is where the trade-offs live. The case is palm-sized and slips into a pocket, the buds use secure-fit wingtips for a stable acoustic seal, and the enclosure mixes plastic with silicone. Water resistance is IPX5 — fine for sweat and light rain, but a step below the Rulefiss. Warranty is one year. The color is black, and it's aimed at adults.
Who should skip it? If your priority is the clearest possible voice pickup on work calls, or if you train hard enough to soak your earbuds regularly, the MS120's lighter water rating and simpler mic story make it the weaker fit.
• Best for clear calls and voice pickup → Rulefiss Earbuds Sport (four mics with ENC noise reduction).
• Best for battery life → MINISO MS120 (70 hours total versus 56).
• Best for workouts and running → Rulefiss Earbuds Sport (IP-X7, 45° earhooks, 8g per bud).
• Best for travel and pocket carry → MINISO MS120 (palm-sized case, LED digital display, built-in flashlight).
• Best for casual commutes and light rain → MINISO MS120 (IPX5 and secure-fit wingtips).
• Best for the newest Bluetooth spec on paper → MINISO MS120 (Bluetooth 6.0 versus 5.4).
• Best for longer single-charge sessions → MINISO MS120 (8 hours per charge versus 6–8).
• Best for laptop and cross-device versatility → Rulefiss Earbuds Sport (iOS, Android, PC, tablets, laptops, smart watches).
If I were buying one pair for zoom calls plus a mix of gym work, I'd take the Rulefiss Earbuds Sport. The four-microphone array with ENC noise reduction is the single most relevant spec for anyone who spends their day talking into a laptop, and the IP-X7 rating means I'm not babying them between meetings and workouts. The MINISO MS120 is the smarter buy if your life looks more like long flights, commutes, and evenings where a flashlight in your earbud case actually earns its keep — its 70-hour total is genuinely hard to argue with. Both are in-ear designs, so if you specifically want over ear headphones for zoom calls, neither is the right shape and you should look elsewhere. For everything in between, the Rulefiss wins on calls and durability; the MINISO wins on stamina and clever extras. Check the current price on Amazon before you commit, since that's the one variable I can't weigh in for you.
Rulefiss, in my opinion. It lists four microphones with ENC noise reduction and CVC 8.0 call technology, which is a more deliberate call-focused design. The MINISO MS120 handles hands-free calls fine, but its sheet emphasizes battery and the flashlight rather than voice pickup.
That's the total figure with the charging case. Individually, the buds are rated for 7–8 hours of continuous listening per charge. The Rulefiss is similar per charge at 6–8 hours, but tops out at 56 hours total.
The sheet lists IP-X7 waterproofing, which is the stronger rating here — it's specifically framed around protecting against sweat and rain during sports. The MINISO MS120 carries IPX5, which covers sweat and light rain but is a lower tier.
The Rulefiss sheet explicitly states it is not compatible with gaming devices, despite listing a low-latency figure. The MINISO MS120's sheet doesn't make a gaming claim either way, so I wouldn't buy either one primarily for that.
