How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a lighter, sport-focused earbud with a bigger driver and a longer warranty, choose Donerton Earbuds; if you need stronger active call-noise cancellation, IP7 water protection and a matte-black finish, choose Cillso Earbuds.
• Donerton Earbuds — biggest strength: 13mm dynamic drivers, a 3.9g-per-bud weight and a 24-month repair promise with 24-hour response support.
• Donerton Earbuds — biggest trade-off: The noise control is listed as sound isolation, not active ENC, so call clarity leans on the CVC algorithm and the fit rather than on cancelling the noise around you.
• Cillso Earbuds — biggest strength: A 14.2mm driver paired with ENC noise reduction that the spec sheet says blocks out 85% of surrounding noise, plus IP7 waterproofing.
• Cillso Earbuds — biggest trade-off: Shorter coverage (30 days without returns, 180 days of service) and a plastic build with no fabric element in the enclosure.
• Who Donerton is for: Anyone who wants a barely-there bud for workouts and long listening sessions and values a long support window.
• Who Cillso is for: Anyone who takes a lot of calls in noisy places and wants a bud that survives sweat and rain.
The Donerton W90 is built around sound hardware first. Inside each bud sits a 13mm dynamic driver with a polymer diaphragm, tuned across a 20Hz–20,000Hz range. That's a full-range spec, and the design brief is clearly about texture and separation rather than one-note bass. Combined with the CVC algorithm on the microphones, the idea is that voices come through cleanly even when the world around you isn't.
The practical story is the weight. Each bud is 3.9g, and the case is compact enough to slide into a pocket without a bulge. The fit is ergonomic and, per the design notes, doesn't protrude from your ear — which matters if you wear a helmet, a cap or glasses and don't want the bud catching on anything. Four replacement ear caps ship in the box, so you can actually dial in the seal rather than accepting whatever tip comes pre-installed. Silicone and fabric materials in the enclosure suggest a softer, less plasticky feel against the skin.
Buy it if you want a light, full-range bud for gym sessions, runs and long listening days, and you like the idea of a 24-month repair window backing the purchase. Skip it if your priority is actively suppressing background noise on calls — the Donerton approach is isolation, not ENC.
Cillso Earbuds: Who It's For
The Cillso H97 reads like a call-first earbud. The 14.2mm dynamic driver is the largest here, and with 32-ohm impedance and 110dB sensitivity it's an easy load for a phone to drive — you shouldn't need to push volume to get output. The tuning language points to deep bass, smooth mids and clear treble, so it's aimed at a warm, full presentation rather than a flat monitor sound.
Where it separates itself is noise handling. The spec calls it Environmental Noise Cancellation, with ENC microphones on board and a stated 85% reduction of surrounding noise like wind and traffic. That's the number that matters if you're the person taking calls from a street corner, a train platform or a windy parking lot. The buds also carry IP7 waterproofing against sweat, splashes and light rain, and a magnetic adsorption structure in the case that keeps them seated.
The rest of the package is conventional but complete: Bluetooth 5.4 with a high-sensitivity antenna and Hall switch for auto-pairing on opening the case, 15-meter range, ultra-low latency for video sync, touch controls that include voice-assistant wake, and the same 40-hour total / 8-hour single-charge battery shape as the Donerton, with a 1.5-hour USB-C charge and an LED display on the case. Each bud is 4g, and the ergonomic in-ear shape is designed to relieve canal pressure for all-day wear.
Buy it if calls are your main use and you want a bud that shrugs off sweat and weather. Skip it if you want the longest possible support commitment — the coverage here is 30 days for returns and 180 days of service, and there's no fabric in the enclosure.
Side-by-Side: Which Should You Choose?
• Best for workout and gym use → Donerton Earbuds. 3.9g per bud, a non-protruding ergonomic shape and four spare ear caps for a secure fit.
• Best for water and sweat resistance → Cillso Earbuds. IP7 waterproofing beats the Donerton's isolation-only, waterproofing-unspecified approach.
• Best for raw driver size → Cillso Earbuds. 14.2mm versus 13mm, with the higher sensitivity to match.
• Best for long-term peace of mind → Donerton Earbuds. A 24-month repair promise with 24-hour response is the longer support runway.
• Best for the lightest carry → Donerton Earbuds. 3.9g per bud and a slim case that disappears into a pocket.
• Best for video and gaming sync → Cillso Earbuds. Ultra-low latency is an explicit design goal there.
• Best if you dislike glossy white plastic → Cillso Earbuds. Matte black buds and case, with a plastic enclosure.
In my opinion, most people shopping these two should pick the Cillso Earbuds. The 14.2mm driver, the ENC microphones with that 85% noise-reduction figure, and IP7 waterproofing cover the three things that actually annoy earbud owners: thin sound, muffled calls and dead buds after a sweaty run. I'd only steer you to the Donerton Earbuds if you specifically want the lighter 3.9g fit and the much longer support window — for a pure gym-and-music bud, that's a defensible choice. Check the current price on Amazon before you commit, since that's the one variable I can't compare for you.
Cillso, on paper. It uses Environmental Noise Cancellation microphones with a stated 85% reduction of surrounding noise, which is a more aggressive approach than the Donerton's sound isolation plus CVC algorithm. If you take calls outdoors or in traffic, the Cillso design targets that problem directly.
Do both have the same battery life?
Effectively yes. Both list 8 hours of playback per charge, 40 hours total with the case, and a 1.5-hour USB-C charge time. Both also have LED power displays on the case. The Donerton's display is described as dual, showing buds and case separately.
They're aimed at different presentations. Cillso uses a larger 14.2mm driver with high sensitivity for a warm, bass-forward sound. Donerton uses a 13mm driver with a polymer diaphragm tuned for a balanced three-channel framework. Neither is objectively "better" — it comes down to whether you want weight and warmth or balance and texture.
Yes. Donerton advertises a 24-month repair service with 24-hour response. Cillso lists 30 days without returns and 180 days of 24-hour customer service. If the length of coverage matters to you, Donerton is the safer pick.
