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 LDAC hi-res audio for flights, trains and open-plan offices, choose Anker Soundcore Space One; if you need featherweight open-ear comfort that keeps you aware of traffic while streaming LDAC all week, choose Linklike C-Flow Open Ear.
• Anker Soundcore Space One — biggest strength: over-ear active noise cancellation with adaptive calibration, LDAC hi-res support from 40 mm dynamic drivers, and up to 40 hours of ANC playtime (55 hours average battery life per the spec sheet).
• Anker Soundcore Space One — biggest trade-off: it's a sealed over-ear design, so you're isolated from the world around you, and there's no wired jack to fall back on.
• Linklike C-Flow Open Ear — biggest strength: a 4.7 g clip-on build with a patented Z-structure, 9 hours per charge and up to 70 hours with the case, plus Hi-Res LDAC streaming over Bluetooth 6.0.
• Linklike C-Flow Open Ear — biggest trade-off: it deliberately has no noise cancellation, so loud environments will bleed into your music.
• Who each pick is for: the Space One is for people who want to block the world out; the C-Flow is for people who want to keep the world in.
The Space One is Anker's over-ear noise cancelling model, and the spec sheet tells you exactly what it's built around: concentration. Adaptive noise cancellation recognizes outside noise and recalibrates on its own, and Anker claims up to 98% noise suppression under lab conditions. That's the kind of design you buy for a commuter train, a crowded café or a shared office where you can't control what's happening around you.
The audio side is where the LDAC angle matters. A custom 40 mm dynamic driver supports LDAC for high-resolution wireless streaming, and Anker frames that as roughly three times the precision of standard Bluetooth audio. Bluetooth 5.3 handles the connection, and everything including noise control runs through the companion app. Battery is genuinely generous — a 2-hour charge, 40 hours with ANC on, and a 55-hour average battery life figure in the product data.
Who should buy it: anyone who treats headphones as a wall. Long-haul flights, noisy commutes, deep-focus work sessions. Who should skip it: runners, cyclists, and anyone who needs to hear a car horn or a colleague calling their name. This is a sealed over-ear headphone with no headphone jack, so wired listening isn't an option either. Note too that this particular listing is a renewed unit, which is worth factoring into your decision.
The C-Flow goes the opposite direction on purpose. Linklike states plainly that the earbud has no noise cancellation by design — it's meant to keep you safe, aware and connected to your surroundings. Instead of sealing your ear canal, the clip-on shape sits outside it, and the 4.7 g weight combined with the patented Z-structure is engineered to redistribute that weight so there's no pinching or downward drag.
There's more engineering here than the size suggests. A 13 mm dual-magnet LCP driver pushes the sound, 16Ω impedance smooths out harsh treble, and a patented directional acoustic steel mesh focuses audio into your ear canal to limit sound leakage — useful in a quiet office or an elevator. LDAC and certified Hi-Res support mean you're not sacrificing streaming quality for the open design. Bluetooth 6.0 with dual-device multipoint lets you jump from a laptop video to a phone call without re-pairing.
Battery is the headline: 9 hours per charge, 70 hours total with the charging case, and a quick 1.5-hour charge time. IP55 means sweat and light rain are fine. Who should buy it: runners, cyclists, warehouse and delivery workers, and anyone who wears earbuds for a full workday and hates the ache that comes with it. Who should skip it: anyone who wants to silence a plane cabin or a loud train.
• Best for noise blocking → Anker Soundcore Space One. Adaptive ANC with up to 98% suppression (lab-tested by the brand) is the whole point of this headphone.
• Best for all-day comfort → Linklike C-Flow Open Ear. At 4.7 g per earbud with a pressure-redistribution design, it's built to disappear on your ears.
• Best for total battery life → Linklike C-Flow Open Ear. Up to 70 hours with the case beats the Space One's 55-hour average battery figure.
• Best for single-charge endurance → Anker Soundcore Space One. 40 hours of ANC playback on one charge is a long stretch between plug-ins; the C-Flow gives you 9 before you need the case.
• Best for awareness and safety → Linklike C-Flow Open Ear. No ANC is a feature here, not a flaw — you stay tuned into traffic and surroundings.
• Best for focus and isolation → Anker Soundcore Space One. Over-ear sealing plus app-controlled ANC is the better call for open offices and flights.
• Best for newer Bluetooth → Linklike C-Flow Open Ear. Bluetooth 6.0 with dual-device multipoint versus Bluetooth 5.3.
• Best for durability against sweat and rain → Linklike C-Flow Open Ear. IP55 rating; the Space One sheet doesn't list an IP rating at all.
Both support LDAC, so if hi-res streaming is your priority you're not choosing between them on codec — you're choosing between isolation and awareness.
In my opinion, the right pick comes down to one question: do you want to hear the world or block it? If your listening happens on planes, trains and in busy offices, I'd buy the Anker Soundcore Space One — the adaptive ANC, 40-hour ANC playtime and over-ear seal are exactly what that environment demands. If your listening happens while moving through the world — running, cycling, working on your feet — I'd buy the Linklike C-Flow Open Ear. The 4.7 g weight, 70-hour total battery and IP55 rating fit that life far better, and LDAC means you're still getting hi-res audio either way.
what is ldac headphones
LDAC is a high-resolution Bluetooth audio codec that carries more audio data than standard Bluetooth streaming, so compatible headphones can play higher-quality wireless audio. Both the Anker Soundcore Space One and the Linklike C-Flow Open Ear list LDAC support in their specs.
what is ldac support in headphones
It means the headphone can receive an LDAC stream from a compatible source device, such as an Android phone set to prioritize audio quality. On the Space One, LDAC works alongside a 40 mm dynamic driver; on the C-Flow, it pairs with a 13 mm dual-magnet LCP driver.
what is ldac codec in headphones
It's the compression method used to send audio over Bluetooth, and it's the reason both of these models can claim hi-res wireless playback. Keep in mind your phone has to support LDAC too — the headphone side alone isn't enough.
what is ldac sony headphones
LDAC was developed by Sony and is used across a range of headphones, not just Sony's own. Anker and Linklike both license it here, so you get the codec without being locked into one brand.
Whichever way you lean, check the current price on Amazon before deciding — the two sit in very different places in the headphone market.
