Sound Quality
Soundcore Space A40
Balanced sound signature with punchy bass. Customizable via the Soundcore app with extensive EQ options. LDAC support means hi-res audio streaming on Android devices—a rare feature at this price point.
The default tuning leans slightly bass-heavy, but the app lets you adjust to your preference.
Sony WF-C700N
Sony’s tuning expertise shows here. Warmer, more refined sound with better instrument separation. The bass is present but controlled, and vocals sound natural.
No LDAC (surprising for Sony), only AAC and SBC. Sound quality is excellent for the codec limitations.
Winner: Sony for pure sound quality. Soundcore for flexibility and hi-res potential.
Active Noise Cancellation
Soundcore Space A40
Adaptive ANC that adjusts to your environment automatically. Claims up to 98% noise reduction. In practice, it handles airplane and train noise very well—better than expected at this price.
Multiple ANC levels available in the app.
Sony WF-C700N
Effective ANC that’s smooth and natural-sounding. Sony’s noise cancellation feels more refined, without the “pressure” sensation some budget ANC causes.
Not as strong as Sony’s flagship models, but solid for the price.
Winner: Tie. Space A40 for raw power, Sony for natural feel.
Battery Life
This isn’t close.
| Space A40 | WF-C700N | |

| Earbuds only (ANC on) | 10 hours | 7.5 hours |
| With case | 50 hours | 15 hours |
| Quick charge | 10 min = 4 hrs | 5 min = 1 hr |
Winner: Soundcore Space A40, decisively.

Fit and Comfort
Soundcore Space A40

Winner: Tie—both comfortable for extended wear.
Call Quality
Neither excels here, but both are adequate.
