At one end, a $300+ flagship with the world's best ANC chip. At the other, a $60 budget powerhouse with 50 hours of battery life and LDAC. The Soundcore Space A40 shouldn't be this good — but it is. Here's how far apart these two earbuds actually are.

Battery Life: Space A40's Killer Feature
The Soundcore Space A40 wins battery by a landslide. Its 50-hour total ANC-on figure is not marketing spin — the earbuds genuinely deliver 8–9 hours per charge and the case charges them roughly five more times. The Sony WF-1000XM6 manages 24 hours total. For business travellers, long-haul commuters, or anyone who forgets to charge, the Space A40's battery life is practically liberating. You can use them for a week of daily commutes without reaching for a charging cable.
ANC: Where Sony Still Wins
The Space A40's ANC is genuinely impressive for a sub-$80 earbud — it makes open offices and bus commutes meaningfully quieter. But the Sony WF-1000XM6 with its QN2e chip applies noticeably more suppression to low-frequency rumble (aircraft engines, train motors) and handles mid-frequency sounds like conversations more effectively. In a quiet library or home setting, both feel similar. On a noisy A320 flight, the Sony's advantage is clear and significant.
Pros and Cons
Sony WF-1000XM6
Pros
- Sony QN2e chip delivers the most effective ANC of any true wireless earbud on the market
- LDAC + aptX give hi-res wireless audio enthusiasts the highest available codec quality
- Superior call quality with AI beamforming microphones for noise-polluted environments
- Speak-to-Chat, Adaptive Sound Control, and DSEE Extreme are genuinely useful smart features
- Excellent transparency / Ambient Sound mode that sounds near-natural
- Proven Sony ecosystem with mature app and long firmware update track record
Cons
- Costs 4–6× more than the Space A40 — the most significant premium in this comparison
- Battery case capacity of 24 hours total is dramatically outclassed by Space A40's 50 hours
- IPX4 rating is identical to Space A40 — no advantage in durability for the premium
- Marginal ANC advantage over Space A40 may not justify $250 extra for casual listeners

Frequently Asked Questions
Frequently Asked Questions
Is the Soundcore Space A40 really good enough to compete with the Sony WF-1000XM6?
For casual listening, commuting on buses and metros, and everyday use — yes, the Space A40 delivers 70–75% of the XM6's performance at 20% of the price. For aircraft travel, critical listening, and demanding call scenarios, the Sony pulls clearly ahead.
How is the Soundcore Space A40 battery life 50 hours?
Anker's battery engineering is exceptional value. The earbuds themselves deliver around 9 hours per charge with ANC on, and the case holds enough additional charge for roughly 4–5 full top-ups, resulting in 50 hours total ANC-on listening. It's genuinely the best battery life at any price in this category.
Does the Space A40 support LDAC like the Sony?
Yes — the Soundcore Space A40 supports LDAC on Android, which is remarkable at its sub-$80 price. You get hi-res wireless audio quality that was unthinkable at this price point just a few years ago.
Which earbuds are better for long-haul flights?
The WF-1000XM6 wins for long-haul flights on two dimensions: superior ANC that handles jet engine rumble more completely, and better overall sound quality for a 10-hour journey. However, the Space A40's 50-hour battery means you never worry about charging mid-trip — a practical advantage.
Are the Space A40 good for gym workouts?
Yes. Both earbuds have IPX4 splash resistance and secure ear tip fits. The Space A40's lower price actually makes it a psychologically easier choice for sweat-intensive gym use where you're less worried about damage.
What is Hear ID on the Soundcore app?
Hear ID is Soundcore's personalised sound test that plays tones at different frequencies to map your hearing profile and then applies a custom EQ curve tailored to your individual hearing sensitivity. It can significantly improve audio quality, particularly for users with any high-frequency hearing variation.
Does the WF-1000XM6 have a better app than the Soundcore app?
Both are well-designed. Sony Headphones Connect offers DSEE Extreme upscaling, Adaptive Sound Control, Speak-to-Chat, and firmware updates. Soundcore offers Hear ID personalisation, comprehensive EQ, and ANC level adjustments. Sony's app is slightly more feature-rich overall.
Should I buy the Space A40 or save up for the Sony XM6?
If the $250+ difference represents a meaningful financial consideration, buy the Space A40 without hesitation — it is objectively one of the best value earbuds ever made. If you fly frequently, take many important calls in noisy environments, or care deeply about codec quality, save for the Sony.
