• Picun's biggest strength: True active noise cancelling in an over-ear design, with 40mm Hi-Res dynamic drivers, a 3.5mm aux fallback and a 20-meter Bluetooth range.
• Picun's biggest trade-off: It's a full-size 200g headphone, and the spec sheet lists a 4-hour average battery life figure alongside its 40-hour headline claim, so heavy ANC users should plan to charge often.
• Cillso's biggest strength: True wireless freedom in a 4-gram-per-bud package, with Bluetooth 5.4, IP7 waterproofing and an LED charging case that totals 40 hours.
• Cillso's biggest trade-off: It's in-ear only, has no wired jack, and its noise control is ENC (call noise reduction) rather than active noise cancelling for your music.
• Buy Picun if you want immersive ANC and deep bass over your ears for travel, home and desk work.
• Buy Cillso if you want featherweight buds that survive sweat, rain and workouts with a battery case in your pocket.
The Picun ANC-05L is built around one idea: shut the world out. Its active noise cancelling is the headline feature, and the brand claims it reduces noise in aviation, subway, car and crowded environments by up to 95%. Whether or not that number lands exactly for you, the design logic is sound — memory foam over-ear cushions create a physical seal first, then the ANC electronics handle the low-frequency rumble a seal alone can't touch. That combination is what makes over-ear ANC genuinely useful on a plane or in an open office, and it's something no in-ear bud without ANC can replicate.
Sound-wise, Picun uses 40mm dynamic drivers with Hi-Res certification, a frequency range of 20Hz to 20,000Hz, 32 ohm impedance and 35dB sensitivity. In plain terms: big drivers, deep bass, clear treble. The Bluetooth 5.3 chip handles the wireless connection up to 20 meters, and there's a 3.5mm aux cable in the box for PCs, desktops and anything without Bluetooth — which matters more than people expect for remote meetings and older hardware. Note the brand's own caveat that the microphone only works in Bluetooth mode, not over the aux cord.
Who should buy it: travellers, remote workers, students, and anyone who wants one headphone for music, movies and calls at a desk. Who should skip it: runners and gym-goers who hate bulk, and anyone who wants buds that disappear into a pocket.
Cillso Earbuds: Who It's For
The Cillso H97 takes the opposite approach: get out of the way. Each bud weighs 4 grams, which is about as close to nothing as in-ear audio gets, and the ergonomic airflow structure is designed to relieve pressure in the ear canal so you can wear them all day without soreness. For people who've given up on earbuds because they ache after an hour, that design detail is the whole pitch.
The audio hardware is a 14.2mm dynamic driver covering 20Hz to 20kHz, with 110dB sensitivity and 32 ohm impedance. That's a high-sensitivity, easy-to-drive setup — phones won't struggle to push volume out of it. The 3D bass stereo tuning aims squarely at pop, hip-hop and gaming soundtracks. Connectivity is the newer Bluetooth 5.4, which Cillso says cuts power consumption by 30% and improves signal penetration by 35% over 5.3, with auto-pairing via a Hall switch when you open the case, working within about 15 meters.
Calls get real attention here. There are four ENC microphones running an algorithm the brand says cuts background noise like wind and traffic by 85% — so the person on the other end hears you, not the street. That's the key distinction: Cillso's "noise cancelling" is environmental noise cancellation for your voice, not active noise cancelling for your ears. Your music will still let the world in.
Who should buy it: gym-goers, runners, commuters and anyone who wants buds for workouts and calls. Who should skip it: frequent flyers who want to mute engine drone, and anyone who needs a wired option — there's no jack here.
Side-by-Side: Which Should You Choose?
• Best for active noise cancelling → Picun Active Noise Cancelling. It's the only one of the two with real ANC; Cillso's noise control is for calls, not listening.
• Best for workouts and rain → Cillso Earbuds. IP7 waterproofing and 4-gram buds beat a 200g over-ear headphone for training.
• Best for battery confidence → Cillso Earbuds. The 8-hour-per-charge and 40-hour-with-case figures, plus the LED display, are easier to trust than Picun's conflicting 4-hour and 40-hour numbers.
• Best for deep bass and big sound → Picun Active Noise Cancelling. 40mm drivers and Hi-Res tuning simply move more air than 14.2mm buds.
• Best for calls in windy or noisy places → Cillso Earbuds. Four ENC mics with an 85% background-noise reduction claim are purpose-built for this.
• Best for wired flexibility → Picun Active Noise Cancelling. The 3.5mm aux cable covers PCs, desktops and non-Bluetooth gear.
• Best for travel packing → Cillso Earbuds. A charging case slides into any pocket; Picun folds but still takes up real bag space.
• Best for marathon listening sessions → Picun Active Noise Cancelling. Memory foam over-ear cushions are kinder to ears over hours than in-ear tips.
If I had to pick one, I'd buy the Picun Active Noise Cancelling headphones. In my opinion, real active noise cancelling plus 40mm drivers and a wired fallback is a more versatile package for the money — it covers flights, offices, movies and desk calls in one device. That said, I'd steer anyone whose priority is the gym, running or all-day featherweight comfort to the Cillso Earbuds instead. They're two different tools, and the right answer depends entirely on where you'll wear them. Check the current price on Amazon for both before deciding.
Yes, for listening. Picun uses active noise cancelling to reduce ambient sound around you. Cillso's ENC system only cleans up your voice on calls — it doesn't block noise from reaching your ears.
No. Their noise control is Environmental Noise Cancellation, which works on the microphone side during calls. Your music will still let surrounding sound through.
Yes. A 3.5mm aux cable is included and works with PCs and desktops, but the microphone only functions in Bluetooth mode, not over the cable.
Cillso's numbers are clearer: 8 hours per charge and 40 hours with the case. Picun claims 40 hours total but also lists a 4-hour average life figure, so expect shorter runtime with ANC on.
