• KGUSS Topping DX3pro+ biggest strength: a proper desktop DAC/amp with the ES9038Q2M decoder, XMOS XU208 USB, and LDAC over Bluetooth 5.0 — it drives both sensitive IEMs and power-hungry high-impedance headphones.
• KGUSS Topping DX3pro+ biggest trade-off: it is a stationary box that needs DC 15V/1A power. You supply your own headphones, and there is no battery and no ANC.
• Anker Soundcore Space One biggest strength: wireless freedom with Adaptive ANC, 40mm dynamic drivers, LDAC Hi-Res support, and up to 40 hours of ANC playtime (55 hours with ANC off).
• Anker Soundcore Space One biggest trade-off: it is a complete wireless headphone rather than a component, so you cannot swap in your own headphones or feed it optical/coaxial sources.
• For the desktop listener who wants maximum wired fidelity and Bluetooth flexibility → KGUSS Topping DX3pro+.
• For the traveller who wants one self-contained, noise-cancelling LDAC headphone → Anker Soundcore Space One.
The DX3pro+ is a converter and amplifier first. It takes USB, optical, coaxial, or Bluetooth and turns that signal into something your wired headphones can actually use. The important part for our comparison angle is Bluetooth: the QCC5125 chip supports LDAC, AAC, SBC, APTX, APTX LL and APTX HD. So if your phone, tablet or laptop transmits LDAC, the DX3pro+ receives it and hands it to the ES9038Q2M decoder. That is the "LDAC headphones" idea in reverse — you keep your favourite wired headphone and get wireless convenience into it.
On the wired side it is genuinely serious. The second-generation eight-core XMOS XU208 handles USB up to PCM 32bit/768kHz and DSD512 native. The NFCA circuit is tuned for this unit, and the published THD+N figure of 0.00015% is the kind of number that tells you the engineering team cared. Topping says the amp pairs nicely with both high-sensitivity IEMs and power-hungry high-impedance headphones — that range matters, because plenty of cheap amps hiss with IEMs or run out of steam with big planars.
Skip it if you want to walk around with music on your head. There is no battery, no noise cancelling, and no drivers of its own.
Anker Soundcore Space One: Who It's For
Space One is the opposite philosophy: one finished product you put on your head and forget about. It is an over-ear wireless headphone with 40mm customised dynamic drivers, a 20–20000 Hz range, 16 ohm impedance, and Bluetooth 5.3 with roughly 10 metres of range. It supports LDAC for Hi-Res wireless audio, which Anker describes as delivering about three times more detail than standard Bluetooth codecs. That is the same LDAC story as the Topping, just delivered to your ears instead of to a separate amp.
The headline feature is Adaptive Noise Cancelling. It detects external sounds and sound leakage, then auto-calibrates — useful when your glasses or hair break the seal and ANC normally falls apart. Anker says it is especially effective against low-frequency, continuous noise: engine rumble, air-conditioner hum, train drone. There are five adjustable ANC levels in the soundcore app, so you can dial the cancellation to your environment instead of accepting one fixed mode.
Battery is the other reason people buy it. 40 hours with ANC on, 55 hours with ANC off, and a full charge takes about 40 hours. Controls are touch-based on the earcup. Comfort is clearly a design priority: 8° rotating ear cups and a soft integrated headband that spreads pressure. There is a 3.5 mm jack for wired listening, a carry pouch, and an 18-month warranty.
Buy it if you commute, fly, study in cafés, or just want one pair of headphones for everything. Skip it if your priority is driving a collection of wired headphones or feeding a desktop speaker setup.
• Best for desktop sound quality → KGUSS Topping DX3pro+. The ES9038Q2M decoder, XMOS XU208 USB and NFCA amp stage are built to squeeze the most out of wired headphones.
• Best for wireless freedom → Anker Soundcore Space One. No cable, no wall power, no separate amp.
• Best for LDAC listening on the move → Anker Soundcore Space One. LDAC is built into the headphone itself, so your phone streams straight to your ears.
• Best for LDAC flexibility with your own headphones → KGUSS Topping DX3pro+. It receives LDAC and passes it to whatever wired headphone you already love.
• Best for noise cancelling → Anker Soundcore Space One. Adaptive ANC with five adjustable levels, tuned for low-frequency drone.
• Best for battery life → Anker Soundcore Space One. 40 hours with ANC on, 55 with it off.
• Best for a fixed desk setup → KGUSS Topping DX3pro+. USB, optical, coaxial, line out, pre-amp mode and a remote make it a hub, not a gadget.
• Best for travel and commuting → Anker Soundcore Space One. Rotating cups, a carry pouch and a 3.5 mm jack for in-flight use.
In my opinion these two barely compete — they solve different problems, and the right answer depends entirely on where you listen. If I were building a desk setup around wired headphones, I would buy the KGUSS Topping DX3pro+ without hesitation: it is the more capable piece of audio engineering here, and LDAC support means you are not locked to a cable. But if I wanted one pair of headphones for trains, planes and open-plan offices, I would buy the Anker Soundcore Space One. It gives you LDAC, adaptive ANC and 40 hours of ANC playtime in a single comfortable package. Pick the Topping for the desk, the Space One for the world.
what is ldac headphones
LDAC is a high-resolution Bluetooth audio codec, and "LDAC headphones" simply means headphones that can receive it. Both products here support LDAC: the Anker Soundcore Space One decodes it internally using its 40mm drivers, while the KGUSS Topping DX3pro+ receives LDAC via its QCC5125 chip and sends the audio to your wired headphones.
what is ldac support in headphones
It means the headphone can accept an LDAC stream from a compatible phone, tablet or laptop instead of falling back to SBC or AAC. On the Space One, LDAC is part of the Hi-Res wireless audio feature set. On the Topping DX3pro+, LDAC is one of several supported protocols alongside AAC, SBC, APTX, APTX LL and APTX HD.
A codec is the method used to compress and transmit audio over Bluetooth. LDAC is a higher-detail option, and Anker states the Space One's LDAC support delivers roughly three times more detail than standard Bluetooth codecs. The Topping DX3pro+ lists LDAC support through its Bluetooth 5.0 QCC5125 chip, so it works the same way on the receiving end.
is the Anker Soundcore Space One worth it over the Topping DX3pro+?
They are not substitutes. The Space One is a complete wireless headphone with ANC, 40-hour ANC battery life and touch controls. The DX3pro+ is a desktop DAC and amp with no drivers, no battery and no ANC, built to improve wired headphones. Buy based on whether you want headphones or a component — and check the current price on Amazon before deciding.
