If you want a do-everything pair of over-ear headphones that can run for days, hold a stable wireless link through long work sessions, and give you a genuinely useful transparency mode for Zoom calls, choose FIO MOTUS Hybrid Active Noise; if you need pocketable wireless earbuds with a touchscreen charging case, a real IPX7 waterproof rating and enough battery to cover a commute plus a work shift, choose Thunelec Earbuds.
FIO MOTUS Hybrid Active Noise vs Thunelec Earbuds at a Glance
• FIO MOTUS biggest strength: Hybrid ANC with 4 microphones, a massive 130-hour battery in standard mode (75 hours with ANC on), and 40 mm drivers with Hi-Res tuning up to 40kHz — plus a wired 3.5 mm fallback.
• FIO MOTUS biggest trade-off: It's an over-ear design at 9.44 ounces, so it's a bag-and-desk product, not something you'll slip into a pocket, and the headphones themselves aren't water-rated.
• Thunelec biggest strength: Bluetooth 5.4 with a transparency mode for hearing your surroundings, ANC rated up to 45dB, IPX7 waterproofing, and a full-color touchscreen on the charging case.
• Pick FIO MOTUS if you spend your day in back-to-back calls, want one pair for desk work, travel and movies, and hate charging.
• Pick Thunelec if you want something light and sweat-proof for commuting and workouts, and you like controlling everything from the case instead of your phone.
The FIO MOTUS FM20 is built around three ideas: kill background noise, last forever on a charge, and stay comfortable for hours. The hybrid ANC system uses 4 microphones to target low and mid-frequency sounds — engine hum, air conditioning, the drone of an office HVAC. That's exactly the noise profile that ruins a Zoom call, which is why I'd point anyone hunting for noise canceling open ear headphones for zoom calls toward a proper over-ear instead: this design physically surrounds your ear, so passive isolation and ANC work together.
The spec sheet tells a workhorse story. 130 hours of playback in standard mode, 75 hours with ANC on, and a 10-minute charge that buys 12 hours of listening. For someone who forgets to charge until the battery warning pops up, that's a real quality-of-life feature. Bluetooth 5.3 keeps the link stable across a 10-meter range, and dual connection means you can be paired to a laptop and a phone at once and hop between them. There's also a 3.5 mm jack, so if wireless ever gets flaky mid-presentation, you have a wired fallback. The 40 mm dynamic drivers with a 20Hz–40,000Hz range, 16 ohm impedance and 100dB sensitivity suggest an easy-to-drive, bass-forward tuning, and the spatial audio algorithms aim to put you in the middle of the sound for movies and music. Latency is listed at 38ms, which matters if you ever game or watch video.
Who should buy it: remote workers and students who live in video meetings, frequent travelers, and anyone who wants one pair of bluetooth headphones for zoom calls, movies and music without a daily charging ritual. Who should skip it: gym-goers and runners — there's no water rating here, and an over-ear headphone isn't the right tool for a sweaty workout.
Thunelec Earbuds: Who It's For
The Thunelec U9 is the opposite philosophy: tiny, tough, and controlled from a screen. The headline feature is the full-color touchscreen built into the charging case. Instead of digging your phone out to skip a track or toggle noise cancelling, you tap the case. It also handles wallpaper customization, brightness adjustment, a timer, a headphone-finder function and seven language options. It's a genuinely unusual design choice at this end of the market, and if you find touch controls on earbuds fiddly, it solves a real annoyance.
Noise handling is a two-part system. ANC claims up to 45dB of reduction — enough to blunt traffic, office chatter and the noise of a bus or train. ENC handles the microphone side, cleaning up your voice and suppressing static so callers hear you clearly rather than muffled. On top of that sits transparency mode, which pipes your surroundings back in while you keep listening. That's the feature to care about if you take calls while walking or need to hear a train announcement.
Battery is 6–8 hours per charge and 48 hours total with the case, which refills in about 1.5 hours and shows a battery indicator. That covers a 6-hour work shift or a long trip. Bluetooth 5.4 is claimed at 98% connection stability, with one-tap pairing and multi-device switching across iOS, Android, laptops and smart TVs. The 14.2mm bio-carbon fiber drivers reach down to 50Hz for bass, and there are five EQ presets — standard, classic, jazz, rock and pop — switchable without an app. IPX7 waterproofing means sweat and rain are fine.
Two honest caveats: there's no on-earbud volume control, so you'll use the case screen or your device, and the in-ear fit means isolation depends partly on getting the right silicone tip from the three sizes included.
Who should buy it: commuters, gym users, and anyone who wants pocketable bluetooth earbuds for zoom calls and music with waterproofing and case-based controls. Who should skip it: if you need marathon battery life per charge or prefer an over-ear fit for all-day desk wear, look elsewhere.

I'd buy the FIO MOTUS Hybrid Active Noise. The 130-hour battery, hybrid ANC with four microphones, dual connection and 3.5 mm fallback make it the better tool for the thing most buyers are actually doing: sitting through Zoom calls all day. The transparency mode covers the moments you need to hear the room, and the spatial audio and 40 mm drivers make it a genuine all-rounder for music and movies after hours. The Thunelec is the smarter pick if you need waterproof, pocketable earbuds with a screen on the case — but for desk-bound work, I'd take the over-ears.
Transparency mode uses the microphones to feed outside sound into your ears while audio keeps playing, so you can hear traffic, announcements or a coworker without removing the headphones. On the Thunelec U9 it's a listed feature; on the FIO MOTUS the dual-microphone setup is described as letting you hear real-time sound around you while enjoying music.
On the Thunelec U9 you toggle noise modes from the touchscreen case or the earbud touch controls. On the FIO MOTUS, noise control runs through the button controls and the companion app, where you switch between ANC and standard listening.
It's for safety and quick conversations — walking through a city, waiting for a platform announcement, or answering someone at your desk. It's the reason the Thunelec works well for urban commuters, and it's a useful counterweight to ANC on the FIO MOTUS during a workday.
Both work; it depends on your environment. The Thunelec pairs ENC call noise reduction with transparency mode for portable use, while the FIO MOTUS adds hybrid ANC, four microphones, dual connection and a wired 3.5 mm option — which is why I lean toward it for long meeting days.
