How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want active noise cancelling with true multipoint pairing across two devices at once, choose Lenovo True; if you need an open-ear, sweat-and-swim-proof sport headphone with built-in offline music storage, choose DEMICEA Open Ear Sport.
• Lenovo True — biggest strength: True multipoint with Lenovo Enhanced Multipoint lets you pair two Bluetooth audio devices simultaneously (any mix of phone, laptop or tablet) and auto-switch audio between them, plus adaptive active noise cancelling rated to cut up to 36 dB of ambient noise.
• Lenovo True — biggest trade-off: It's an in-ear design, so it seals your ear canal rather than leaving it open, and it has no built-in music storage — it depends on a connected device for playback.
• DEMICEA Open Ear Sport — biggest strength: Open-ear, 32 g build with IP68 waterproofing, safe for swimming and rinseable under a tap, plus 32 GB of built-in storage for roughly 8,000 songs of offline playback.
• DEMICEA Open Ear Sport — biggest trade-off: No active noise cancelling at all, and its multipoint description is looser — it's framed around switching between devices rather than clearly pairing two at once the way Lenovo states it.
• Who each pick is for: Lenovo True for commuters, remote workers and anyone juggling a phone plus a laptop who wants quiet; DEMICEA Open Ear Sport for swimmers, runners and gym-goers who want to hear their surroundings and leave the phone behind.
The Lenovo Smart True Wireless Earbuds are built around two ideas: cutting noise and staying connected to more than one thing at once. The headline feature is Lenovo Enhanced Multipoint, which lets you pair any two Bluetooth audio devices simultaneously and connect to any combination of phone, laptop or tablet. Once both are paired, the earbuds automatically move your audio from one device to the other — you take a call on your phone, then go back to the podcast on your laptop without re-pairing anything. That's the whole reason this comparison exists, and it's the most clearly stated multipoint implementation of the two.
Noise handling is the second pillar. Smart adaptive noise cancelling adjusts its intensity based on your environment and is rated to reduce up to 36 dB of ambient noise, with six built-in microphones working on voice pickup during calls. You also get Lenovo Fast Pair for Android and Swift Pair for Windows, where pairing mode kicks in as soon as you flip the case open — on Windows, a notification pops up instead of you digging through settings. Battery is rated at up to 28 hours total, with 7 hours on a single charge and three extra charges from the wireless charging case. The 11 mm dynamic drivers and Bluetooth 5.2 round out the package, in an in-ear fit with touch controls and a 10-meter wireless range.
Buy these if your day moves between a phone and a computer and you want the audio to follow you, or if you want noise cancelling for a commute, an open-plan office or a flight. Skip them if you specifically want an open-ear fit so you can hear traffic and conversation, or if you want to leave your phone at home and still have music — there's no onboard storage here.
The DEMICEA Open Ear Sport is a different animal entirely — it's a sport-first, open-ear headphone. At 32 g, it uses a soft liquid silicone casing over a flexible titanium alloy frame that adapts to different head shapes, reinforced with nylon so it springs back under stress instead of staying bent. Because it sits open-ear rather than inside your canal, you keep awareness of what's around you, which is exactly what runners and cyclists tend to want.
The ruggedness claim is the real standout: IP68 waterproofing means it's rated to survive spills and splashes and is described as safe to wear while swimming, with a simple water rinse handling sweat and grime. That's a genuinely different durability tier than a standard in-ear earbud. Audio comes from a 16 mm oversized diaphragm paired with BassBoost enhancement for deeper low-end, and there's 32 GB of built-in storage — around 8,000 tracks you can play with no phone in sight. Battery is rated at 8 hours with a 2-hour fast charge over a 4-pin magnetic charging port that snaps into place without fiddling.
Controls are tactile: three physical buttons rather than touch, which matters when your hands are wet or gloved. Buy these if you swim, run, cycle or lift and want one pair that survives all of it, or if you want offline music without carrying a device. Skip them if noise cancelling is a priority — there is none — or if you want a guaranteed two-device simultaneous pairing setup for work calls and laptop audio.
• Best for true two-device multipoint → Lenovo True, with Enhanced Multipoint pairing two Bluetooth devices at once and auto-switching audio between them.
• Best for open-ear awareness → DEMICEA Open Ear Sport, since the open design leaves your ear canal unblocked.
• Best for total battery life → Lenovo True, rated up to 28 hours with the charging case versus 8 hours on the DEMICEA.
• Best for swimming and heavy sweat → DEMICEA Open Ear Sport, thanks to IP68 waterproofing and a rinse-clean silicone body.
• Best for noise cancellation → Lenovo True, with adaptive ANC rated up to 36 dB; the DEMICEA has no noise control at all.
• Best for phone-free listening → DEMICEA Open Ear Sport, with 32 GB of built-in storage for offline playback.
• Best for wet or gloved hands → DEMICEA Open Ear Sport, with physical three-button controls instead of touch.
• Best for lighter, more forgiving fit → DEMICEA Open Ear Sport at 32 g with a flexible titanium frame that adapts to head shape.
In my opinion, most people shopping this comparison should buy the Lenovo True. Multipoint pairing is the feature that actually changes how you live with a headphone day to day, and Lenovo states it most clearly — two devices paired at once, audio hopping between them automatically. Add adaptive noise cancelling up to 36 dB and up to 28 hours with the case, and it covers work, travel and commuting in one pair.
I'd only point you to the DEMICEA Open Ear Sport if your priority is a specific sport: swimming, hard sweating, or running where you need to hear traffic. For that job, IP68 waterproofing and 32 GB of offline storage beat anything the Lenovo offers. Pick by your hardest use case, not by the spec sheet's length.
FAQ
how to pair multiple headphones
how to pair multiple headphones iphone
On iPhone, pairing a headphone is done through Settings > Bluetooth, and multipoint still operates at the headphone's end. Pair the Lenovo True to your iPhone first, then pair it to a second device; it holds both and moves audio automatically. iOS doesn't let two separate headphones play one stream simultaneously.
how to pair multiple headphones on ipad
Same principle on iPad — connect through Settings > Bluetooth, then add a second device to the headphone's multipoint list. Lenovo's Fast Pair applies to Android and Windows rather than iPad, so on iPad you pair manually, but Enhanced Multipoint still lets the earbuds stay connected to two devices.
how to pair multiple bluetooth headphones
To run two Bluetooth headphones together you generally need a transmitter that supports dual output; a single phone won't do it. If what you actually want is one headphone connected to two devices, that's multipoint — the Lenovo True pairs any two of phone, laptop or tablet at once. The DEMICEA keeps you connected while switching from smartphone to laptop.
