• Soundcore Anker Space One — biggest strength: Up to 98% noise reduction with adaptive ANC, LDAC Hi-Res wireless audio, and 40 hours of ANC playtime (55 hours with ANC off).
• Soundcore Anker Space One — biggest trade-off: It's an over-ear headphone with no wired jack, so it's bulkier to carry and purely wireless.
• SGNICS Earbuds — biggest strength: A 2.01-inch touchscreen charging case, hybrid active ENC for calls, dual-device switching and 40 hours of total playback through the case.
• SGNICS Earbuds — biggest trade-off: Per-charge runtime is around 5 hours, and noise cancelling is tuned for calls (ENC) rather than full immersion-grade ANC.
• Who should pick the Space One: Commuters, travellers and work-from-anywhere listeners who want to shut the world out for hours.
• Who should pick the SGNICS Earbuds: People who want tiny in-ear buds, quick device switching and touch controls in a case they can slip in a pocket.
The Space One is built around one idea: silence on demand. Its adaptive noise cancelling detects what's around you and auto-calibrates, and Soundcore rates it to reduce noise by up to 98% under laboratory conditions, with 2X stronger voice reduction than the older Life Q30. That matters most in the places where noise actually ruins listening — a packed train carriage, a loud café, an open-plan office. The adaptive part is the smart bit: it re-calibrates if the headphones aren't sitting perfectly on your ears, which is exactly when cheap ANC falls apart.
Then there's the sound and the stamina. The 40mm customized dynamic drivers support LDAC, so if you're streaming from a compatible Android phone you're getting noticeably more detail than a standard Bluetooth codec delivers. The frequency range runs 20 Hz to 20,000 Hz, and the fit is over-ear with fabric, silicone and leather in the build. Battery is the headline number: 40 hours with ANC on, 55 hours with it off. That's a genuinely long-haul figure — you can fly, work a full week of commutes and still not think about the charger.
Who should buy it: anyone whose priority is blocking out mid and high-frequency noise (voices, chatter, cabin hum) for hours at a time, and who wants hi-res wireless audio without a cable. Who should skip it: if you want something that disappears into a jeans pocket, or you need a wired fallback, this isn't that product. It's over-ear, it's wireless-only with no headphone jack, and it ships with a protective case sized to fit Soundcore's over-ear range. Controls are app-based, so you'll want to install Soundcore's app to get the most out of it.
The SGNICS LX50 Earbuds take the opposite approach: small, in-ear, and loaded with convenience features you don't normally see at this level. The standout is the 2.01-inch touchscreen charging case — volume, track skipping, call handling and voice assistant activation all happen on the case itself, so you're not fishing your phone out mid-walk. That's a genuinely different interaction model, and for a lot of people it's the reason to pick these over any standard buds.
Audio-wise, you're getting dual dynamic drivers with stereo sound and enhanced bass, plus AAC and SBC codec support. The noise cancelling here is hybrid active ENC — engineered around the built-in microphone to cut ambient noise for clearer calls. So the emphasis is conversations, not total isolation. If you take a lot of calls on a subway platform or a busy street, that's the feature doing the work. The ergonomic in-ear shape is described as lightweight and pressure-free, and the design is intended to stay put during movement, which is what you want for gym sessions or long wears.
Connection is the other strong suit: dual-device pairing with low latency, so you can bounce between a phone and a computer without re-pairing, on both iOS and Android. Battery is around 5 hours per charge and up to 40 hours total with the case, topped up over Type-C. The buds are Bluetooth-only, ABS-bodied, and come with a cable, eartips and a manual, backed by a 60-day return/replacement window.
Who should buy it: commuters and gym-goers who live in their earbuds, take calls constantly, and want touch controls without touching their phone. Who should skip it: if your main goal is deep, adaptive noise cancelling for flights or open offices, the ENC-for-calls design won't match what a dedicated over-ear ANC headphone does.
Side-by-Side: Which Should You Choose?
• Best for battery per charge → Soundcore Anker Space One. 40 hours with ANC on and 55 with it off, versus roughly 5 hours per charge on the SGNICS buds.
• Best for total playback with a case → SGNICS Earbuds. Up to 40 hours total through the charging case, which is plenty for daily rotation.
• Best for call clarity → SGNICS Earbuds. Hybrid active ENC plus a built-in mic is purpose-built for conversations in noisy places.
• Best for sound quality with a compatible source → Soundcore Anker Space One. LDAC Hi-Res wireless and 40mm dynamic drivers give it the detail edge.
• Best for portability → SGNICS Earbuds. In-ear buds and a pocketable case beat an over-ear headphone and its carry case every time.
• Best for switching between devices → SGNICS Earbuds. Dual-device connection with low latency across phone and computer, iOS and Android.
• Best for long, uninterrupted listening sessions → Soundcore Anker Space One. No recharging mid-flight, no case to manage.
In my opinion, the Soundcore Anker Space One is the one I'd buy for myself. The combination of adaptive ANC rated up to 98% reduction, LDAC Hi-Res audio and 40 hours of ANC playtime covers the situations where audio gear actually earns its place — flights, commutes, focus work. The SGNICS Earbuds are the smarter pick if your day is calls, quick device hops and pocket-sized convenience, and the touchscreen case is a genuinely useful twist. But if you can only own one and you care most about quiet and sound, I'd go with the Space One.
