If you want a lightweight, low-profile in-ear bud with a smart LED battery readout and a rock-bottom-fuss fit for everyday listening, choose Btootos Earbuds; if you need a sports-first hook design with a touchscreen case, active noise cancellation and a huge playtime reserve, choose LEEMC Earbuds.
• Btootos Earbuds — biggest strength: a simple, familiar in-ear package with Bluetooth 5.4, dual 14.2mm drivers, ENC call noise reduction, an LED battery display on the case and IP7 waterproofing.
• Btootos Earbuds — biggest trade-off: passive noise isolation only (no active ANC), a 6–8 hour single-charge window, and a touch-control scheme rather than a screen.
• LEEMC Earbuds — biggest strength: a touchscreen charging case that controls playback, volume, EQ presets and camera shutter, plus active noise cancellation, over-ear hooks and up to 40 hours with the case.
• LEEMC Earbuds — biggest trade-off: a bulkier over-ear hook shape, a larger case, and the description notes the case's screen features are not compatible with Samsung and Google phones.
• Who Btootos is for: commuters, students and casual listeners who want a discreet in-ear bud that disappears in the ear and keeps things simple.
• Who LEEMC is for: runners, gym-goers and anyone who wants maximum control from the case and doesn't mind a bigger, sportier design.
The Btootos A90 Pro is built around the idea that most people just want earbuds that connect fast, stay connected and sound full without any ceremony. The Bluetooth 5.4 chipset is the headline here: it's a newer generation of the wireless standard, and the sheet lists a stable range up to 15 metres, automatic pairing and multi-device compatibility. In practice that means you can leave your phone on a desk and walk to the kitchen, or switch between a laptop and a tablet without re-pairing every time.
The audio side is more interesting than the price-tier look suggests. Instead of the usual single small driver, Btootos uses dual 14.2mm low-distortion composite dynamic drivers with a high-resolution decoder and AAC/SBC coding. Two larger drivers generally mean more air moved and a fuller low end than a tiny single driver, which is why the brand leans on "bass stereo" in the name. The 32-ohm impedance is a standard, easy-to-drive figure, so phones and laptops won't struggle. For calls, the ENC (environmental noise cancellation) mic setup focuses on your voice rather than the room — that's a call-clarity feature, not music noise cancelling, and it's worth being clear about the difference.
The practical stuff is where this one earns its place. The charging case has an LED display that shows both the case level and the earbud level, so you know exactly where you stand instead of guessing from a blinking dot. Total playtime is quoted at 36 hours (6–8 hours per charge plus up to 30 hours from the 300mAh case), and the case recharges in about 1.5 hours over USB-C. IP7 waterproofing with a nano coating covers rain and sweat, and the package includes silicone tips in S, M and L, plus a two-year warranty.
Who should buy it: anyone who wants a lightweight, genuinely in-ear bud for music, podcasts, office calls and light workouts, and who values a battery readout over a screen. Who should skip it: if you need active noise cancellation to kill engine drone or gym noise, or you want your earbuds to physically lock onto your ear with a hook, this isn't that product. It's passive isolation and a traditional in-ear seal — good, but a different job.
The LEEMC TP03 is the opposite personality: it's a gadget-forward sports bud, and the touchscreen charging case is the whole reason it exists. That 16-language screen isn't a gimmick bolted on — from the case you can play and pause music, adjust volume, flip between ANC and Transparency, cycle five EQ presets (Normal, Rock, Classic, Pop, Jazz), change one of five wallpapers, start a countdown timer, trigger your phone's camera shutter remotely, and use Find My Earbud to ring a lost bud or locate the last connected position. If you've ever dug a phone out mid-run just to skip a track, that's the problem this design solves.
The fit is unapologetically athletic. Each bud uses a flexible over-ear hook and weighs just 7.1g, which is remarkably light for a hooked design, and the sheet lists IPX7 protection against sweat and rain plus three tip sizes (S/M/L) to dial in the seal. For running, lifting or anything where a standard in-ear bud tends to work its way loose, hooks are the more reliable answer. The trade-off is honest: an over-ear hook is more visible and more involved to put on than a plain bud, and the case itself is chunkier — roughly 8cm long, 3.56cm tall and about 2.06oz, with the whole package listed at 72.8g.
Audio is handled by a single 13mm dynamic driver with a wide 50,000Hz frequency response rating and 107dB sensitivity, tuned for "deep bass and crisp highs" and shaped by those five EQ presets. Unlike Btootos, LEEMC uses true Active Noise Cancellation, with a Transparency mode for hearing traffic or a training partner. Bluetooth 6.0 handles the connection with open-the-lid pairing and the same 15m range, and latency is quoted at 55ms — low enough that lip-sync in video and games shouldn't bother you. Battery is the other big number: 9 hours on a single charge, up to 40 hours with the case, a 75-minute full case charge, and a 10-minute top-up good for about an hour of playback.
One thing to flag plainly, because the sheet does: the description states the case's screen features are not compatible with Samsung and Google phones. If you're on one of those, you lose a lot of what makes this model special. Warranty is 12 months.
Who should buy it: runners, cyclists, gym regulars and anyone who wants ANC plus heavy control from the case and doesn't mind a hook. Who should skip it: people who want a discreet, invisible bud, and Samsung or Google phone owners who'd be paying for a screen they can't fully use.
• Best for active sports → LEEMC Earbuds. Flexible over-ear hooks at 7.1g per bud plus IPX7 sweat and rain protection are built for movement; Btootos relies on a standard in-ear seal.
• Best for noise cancelling → LEEMC Earbuds. It has genuine Active Noise Cancellation with a Transparency mode; Btootos uses passive isolation and sound blocking only.
• Best for long sessions away from a charger → LEEMC Earbuds. 9 hours per charge and up to 40 hours total beats Btootos' 6–8 hours and 36-hour total.
• Best for call clarity on a budget-minded setup → Btootos Earbuds. ENC mic noise reduction is aimed squarely at voice pickup on calls.
• Best for a discreet, everyday in-ear fit → Btootos Earbuds. No hooks, no bulk, silicone tips in S/M/L, and a pale violet finish that reads as low-key.
• Best for battery visibility → Btootos Earbuds. The LED display shows both case and earbud charge at a glance; LEEMC puts that information on its screen instead.
• Best for phone-free control → LEEMC Earbuds. Volume, EQ, ANC modes, camera shutter and a timer all live on the case screen.
• Best for phone compatibility flexibility → Btootos Earbuds. Nothing in its sheet restricts features by phone brand, whereas LEEMC's screen features are noted as incompatible with Samsung and Google phones.
• Best for a longer warranty → Btootos Earbuds. Two years versus LEEMC's 12 months.
If I were buying for myself and my priority was all-day comfort with music, podcasts and calls, I'd take the Btootos Earbuds — the dual 14.2mm drivers, the LED charge display, the IP7 shell and the two-year warranty make it the more forgiving everyday companion, and I don't need ANC for most of my listening. But if I trained seriously, ran outdoors or wanted the case to do the work so I could leave my phone alone, I'd pick the LEEMC Earbuds without hesitating — the hooks, ANC, 40-hour reserve and touchscreen case are a genuinely different, more capable tool. In my opinion the deciding question is simple: do you want a bud that disappears, or a bud that performs? Answer that and the choice makes itself.
FAQ
how to earbuds in pairing mode
how to earbuds work
Both are true wireless buds: each one holds its own driver and battery and streams audio over Bluetooth from your phone, laptop or tablet, then recharges in the case. Btootos uses Bluetooth 5.4 with dual 14.2mm dynamic drivers and ENC call noise reduction; LEEMC uses Bluetooth 6.0 with a 13mm dynamic driver, active noise cancellation and a touchscreen case that also handles volume, EQ and playback.
how to earbuds in ear
Btootos is a standard in-ear design, so you insert the bud and twist slightly until the silicone tip seals — it ships with S, M and L tips, and a good seal is what gives you the passive isolation. LEEMC is an over-ear hook design: seat the tip in your ear canal first, then loop the flexible hook over the top of your ear so it rests behind the ridge. It also includes three tip sizes, and the hook, not the tip, is what keeps it locked during a run.

Day to day, both are tap-and-go. Btootos uses touch controls for play/pause, skipping tracks, answering and ending calls and waking your voice assistant. LEEMC gives you the same touch controls on the buds plus the case screen for volume, ANC/Transparency switching, five EQ presets, a camera shutter and a countdown timer — just remember the case's screen features aren't compatible with Samsung and Google phones.
