• FiiO /Snowsky Retro Nano — biggest strength: dual high-performance DACs with up to 220mW balanced output, LDAC and aptX Adaptive/aptX LL support, plus 3.5mm unbalanced and 4.4mm balanced outputs. It upgrades the gear you already own.
• FiiO /Snowsky Retro Nano — biggest trade-off: it's a component, not a complete listening solution. No earcups, no drivers, no active noise cancelling. You supply the headphones, and it's built from plastic with a 1-year warranty.
• Anker Soundcore Space One — biggest strength: a complete package — 40mm dynamic drivers, LDAC hi-res wireless, adaptive active noise cancelling, Bluetooth 5.3 and a 55-hour average battery life with a 2-hour charge time.
• Anker Soundcore Space One — biggest trade-off: it's a renewed unit, it's over-ear and it's wireless-only with no headphone jack, so you can't run it passively or feed it a wired balanced signal.
• Who the Retro Nano is for: tinkerers and hi-res listeners who want LDAC and wired balanced output from a tiny retro-styled box.
• Who the Space One is for: anyone who wants one pair of headphones that does noise cancelling, calls and long battery life out of the box.
The Retro Nano is a Bluetooth USB DAC amp, and that word "amp" is doing a lot of work. Inside are two high-performance DACs delivering a balanced output power of up to 220mW. It gives you two physical outputs — a 3.5mm unbalanced and a 4.4mm balanced — which means it can drive a genuinely wide range of wired headphones, including ones that need more current than a phone or laptop headphone jack can supply.
Its wireless side is where the LDAC angle lives. It supports LDAC, aptX Adaptive and aptX LL. LDAC is Sony's high-resolution Bluetooth codec, and it's the reason a lot of people search for "ldac headphones" in the first place: it lets far more audio data cross the Bluetooth link than the standard codecs do. The catch most shoppers miss is that LDAC only helps if both ends of the link support it — your phone or player, and the receiving device. The Retro Nano is a receiving device that speaks LDAC, so if your source supports it too, you get the full benefit. aptX LL, meanwhile, is a low-latency codec, which matters if you're piping audio in from a console or PC and don't want lip-sync drift.
The rest of the package is deliberately playful. The UI replicates a classic cassette player in both shape and interface, and there are 8 custom-tuned retro-inspired sound effects, with DIY tuning through an app and a web interface. The battery is a detachable, rechargeable 3.7V lithium cell rated for up to 7.5 hours of continuous playback, and because it's user-replaceable, a dead battery doesn't end the device's life. It ships with a cable, weighs about 0.1 kg, and carries a 1-year warranty.
Anker Soundcore Space One: Who It's For
The Space One is the opposite kind of product: everything is in the box. It's an over-ear wireless headphone built around custom 40mm dynamic drivers, and it supports LDAC for high-resolution wireless audio — so it sits squarely in the "ldac headphones" category on its own, no extra hardware required.
Noise cancelling is the headline feature. The active noise cancellation is adaptive: it recognises outside noise and recalibrates automatically for the best suppression it can manage, and Anker describes the mid- and high-frequency suppression as roughly twice as strong as its earlier Q30 model, with noise suppression quoted at up to 98% under lab conditions. That is a manufacturer figure measured in a lab, so treat it as a directional claim rather than a promise about your commute — but the intent is clear. This is a headphone for the train, the café and the office, and for anyone who mostly wants the world turned down.
Battery is the other big number: a 55-hour average life with ANC on, recharged in about 2 hours. That's the kind of runtime where you stop thinking about charging at all. Bluetooth 5.3 handles the connection, calls are handled with a clear-call setup, and control is app-based rather than by a physical jack — there's no headphone jack at all, so this is a wireless-only headphone. Enclosure materials are listed as silicone, fabric or leather with an over-ear fit, and it comes in pink. Worth noting: this listing is a renewed unit, and the warranty is stated as 3.
Buy it if you want one finished product that handles noise cancelling, calls and long-haul battery with no accessories. Skip it if you want to drive existing wired headphones, need a balanced output, or specifically want a brand-new unit — renewed means it has been through a refurbishment process, and that's a real difference from buying new.
Side-by-Side: Which Should You Choose?
• Best for LDAC out of the box → Anker Soundcore Space One. The LDAC support is built into the headphone itself, with 40mm dynamic drivers behind it.
• Best for noise cancelling → Anker Soundcore Space One. Adaptive ANC rated up to 98% suppression under lab conditions. The Retro Nano has no noise cancelling at all.
• Best for battery life → Anker Soundcore Space One. 55 hours average versus 7.5 hours on the Retro Nano.
• Best for wired and balanced listening → FiiO /Snowsky Retro Nano. 3.5mm unbalanced and 4.4mm balanced outputs, up to 220mW. The Space One has no jack.
• Best for low-latency use → FiiO /Snowsky Retro Nano. aptX LL is a low-latency codec, which is the reason it's relevant when you're wiring audio into a gaming setup.
• Best for replacing a battery years from now → FiiO /Snowsky Retro Nano. The 3.7V lithium cell is detachable and user-replaceable.
• Best for a single-purchase, wear-it-today solution → Anker Soundcore Space One. No pairing with extra hardware, no headphones to source.
If I had to pick one, I'd pick based on what's already on my desk. For anyone who owns decent wired headphones and wants LDAC, balanced output and a genuinely fun little device, I'd buy the FiiO /Snowsky Retro Nano — it does something the Space One can't, which is upgrade the gear you already have, and the 4.4mm balanced output with up to 220mW is the part I'd actually use. For anyone who wants headphones, full stop — especially for noise cancelling on a commute or a long battery — I'd buy the Anker Soundcore Space One. Just go in knowing it's a renewed unit, it's wireless-only, and if you're shopping gaming headphones for Xbox or a wireless headset for Xbox, neither of these is a native console headset — check how your console handles Bluetooth audio before you commit.
FAQ
what is ldac headphones
what is ldac support in headphones
It means the headphone can decode Sony's LDAC codec over Bluetooth, carrying more audio data than standard codecs for higher-resolution wireless playback. The Space One lists LDAC hi-res support; the Retro Nano lists LDAC alongside aptX Adaptive and aptX LL.
what is ldac codec in headphones
It's the codec itself — the compression-and-transfer method used to move audio over the Bluetooth link. Because it's a link between two devices, LDAC only engages when both your source and your headphones (or DAC amp) support it.
what is ldac sony headphones
That phrasing comes from LDAC being developed by Sony, so it's often associated with Sony gear. Other brands license and implement it — which is exactly what both the FiiO /Snowsky Retro Nano and the Anker Soundcore Space One do here.
