If you want active noise cancellation, a touchscreen battery case and voice-assistant control in a single set of earbuds, choose Supersonic IQ Sound IQ-341; if you need long total playtime, water resistance for workouts and an ultra-light fit, choose Kicoeon Earbuds.
• Supersonic IQ Sound IQ-341 — biggest strength: real active noise cancellation plus ENC, dual mics and a touchscreen charging case that shows battery status at a glance.
• Supersonic IQ Sound IQ-341 — biggest trade-off: the earbuds themselves run about 5 hours per charge, so heavy all-day listeners will lean on the case.
• Kicoeon Earbuds — biggest strength: roughly 6 hours per charge and around 30 hours total with the case, IPX7 water resistance and a 3.4 g per-bud weight.
• Kicoeon Earbuds — biggest trade-off: noise control is passive only, so it relies on the seal rather than active cancellation.
• Pick the Supersonic if calls, noise reduction and a display-driven case matter most to you.
• Pick the Kicoeon if battery life, sweat and rain protection, and long-wear comfort matter most.
The Supersonic IQ Sound IQ-341 is built around control and clarity. It pairs Bluetooth 5.3 with a 10 m range, and once you've made the initial connection it re-syncs automatically with your device, which matters if you're the type who pulls earbuds out and expects them to just work. The 20 Hz–20,000 Hz dynamic driver covers the full audible range, and stereo playback is the core of the experience.
What sets it apart is the noise handling. ANC works on the sound around you, while ENC works on the sound going out, and the dual microphones are tuned to reduce ambient noise during calls. I'd point anyone who takes meetings on the move toward this one. Add in-ear detection — audio pauses when a bud comes out and resumes when it goes back in — and touch controls for volume, playback and your voice assistant, and you get a set that's designed to be operated without reaching for your phone. Google Assistant and Siri both activate through the dual mic setup.
The charging case has a 300 mAh capacity and adds up to 15 hours of extra playtime, and the touchscreen display means you can read battery status without guessing. Charging is over USB-C. The earbuds themselves are rated around 5 hours per charge, which is the honest limit here — fine for commutes, calls and an afternoon of work, less ideal if you want to leave the case at home all day. In my opinion, this is the pick for someone who wants noise cancellation, hands-free voice control and a case that tells you what's going on. Skip it if maximum runtime and water resistance top your list.
The Kicoeon Earbuds are the endurance option. A single charge gives over 6 hours of playback, and the charging case brings the total to about 30 hours, with a full case charge taking roughly 1 hour over Type-C. If you're the sort of person who forgets to charge things, that buffer is the whole point. A dual LED digital display shows battery levels for both the earbuds and the case, so you can see what's left before you leave the house.
Sound is handled by 14.2 mm dynamic drivers with polymer diaphragms, and the tuning is described around a balanced three-channel framework that pushes vocals forward. Bluetooth 5.4 is the newer standard here, and the stated range is 15 m — longer than the Supersonic's 10 m, which helps if you wander away from your phone or laptop.
The practical wins are physical. Each bud weighs 3.4 g, which is genuinely light for long sessions, and the shell is sealed with an IPX7 waterproof rating, so sweat and rain aren't a problem. That combination — light weight plus water resistance — is why I'd steer runners, gym-goers and commuters who get caught in weather toward this pair. Calls get ENC noise reduction with a four-mic setup. Touch controls cover play/pause, calls, volume, track switching and voice assistant.
The trade-off is that noise control is passive only. There's no active cancellation, so blocking out a noisy train or a loud office depends on how well the buds seal in your ears. The colorway is purple with a beige case, which is a look you either like or don't. And there's a two-year warranty listed, which is worth noting if durability is a concern.
• Best for noise cancellation → Supersonic IQ Sound IQ-341. It has genuine ANC plus ENC; the Kicoeon relies on a passive seal.
• Best for battery life → Kicoeon Earbuds. About 6 hours per charge and roughly 30 hours total, versus 5 hours plus 15 hours in the case.
• Best for workouts and bad weather → Kicoeon Earbuds. IPX7 water resistance and 3.4 g per bud.
• Best for calls and voice assistants → Supersonic IQ Sound IQ-341. Dual mics, ENC and optimized Google Assistant/Siri activation.
• Best for battery visibility → Supersonic IQ Sound IQ-341. The case has a touchscreen display; the Kicoeon uses a dual LED readout.
• Best for in-ear convenience → Supersonic IQ Sound IQ-341. In-ear detection auto-pauses and resumes playback.
• Best for range and connection stability → Kicoeon Earbuds. Bluetooth 5.4 with a stated 15 m range versus Bluetooth 5.3 at 10 m.
• Best for all-day comfort → Kicoeon Earbuds. The lighter, sealed design is easier to wear for hours.
I'd buy the Supersonic IQ Sound IQ-341. In my opinion, active noise cancellation, dual-mic ENC for calls, in-ear detection and a touchscreen case that shows battery status are the features that change how you actually use earbuds day to day, and Bluetooth 5.3 with auto re-sync keeps it painless. The Kicoeon is the better choice if you run, sweat, or hate charging — its longer total playtime and IPX7 rating are real advantages. But for calls, focus and hands-free control, I'd take the Supersonic.
