Who Should Buy This#
The Soundcore Space A40 hits a sweet spot for listeners who want flagship features from a budget pair. It delivers adaptive ANC, Hi-Res audio, and wireless charging that competing brands reserve for their flagship models.
Perfect for:
- Daily commuters who need reliable noise cancelling on trains and buses without stepping up to AirPods Pro
- Remote workers who want to block out household noise during video calls
- Android users who want LDAC Hi-Res audio that Apple earbuds simply cannot provide
- Frequent travelers who need all-day battery life and fast charging between flights
Design & Build Quality#
The Space A40 earbuds are remarkably compact — smaller than all other Soundcore ANC earbuds. Soundcore's own claim is that they are "smaller than all other soundcore" ANC earbuds, and its product photography is captioned around a "lightweight 4.9g design" per earbud. The rounded ear tip design provides a secure seal that stays put during movement.
The charging case is pocket-friendly and noticeably smaller than cases from Sony or Jabra. It supports both USB-C and Qi wireless charging, a feature rarely found on budget earbuds. The matte black finish resists fingerprints well, and the lid snaps shut with a satisfying magnetic click.
Key Features#
Adaptive Noise Cancelling That Thinks for You#
The Space A40 uses an upgraded noise cancelling system that blocks up to 98% of distracting sounds. What sets it apart is the adaptive mode — it detects your environment and automatically selects the right level of ANC. Walking on a busy street? Full cancellation kicks in. Sitting at a quiet desk? It dials back to save battery. You can also switch to Transparency Mode to hear announcements without removing the earbuds.
Hi-Res Wireless Audio with LDAC#
Soundcore's own line is that "using double-layer diaphragm drivers, Space A40 noise cancelling earbuds produce sound with strong bass, clear mids, and bright treble". On Android devices, you can enable LDAC — a Bluetooth codec that transmits audio at up to 990 kbps, roughly three times the bitrate of standard SBC. The difference is audible: instruments have more separation, vocals feel more present, and the overall soundstage opens up considerably.
50 Hours of Uninterrupted Listening#
Soundcore's headline "10H/50H" is the Normal Mode figure, and its own FAQ publishes the rest: "Normal Mode: Up to 10 hours on a single charge of the earbuds. 50 hours with the charging case. Noise Cancelling Mode: Up to 8 hours on a single charge of the earbuds. 40 hours with the charging case. Transparency Mode: Up to 8 hours on a single charge of the earbuds. 40 hours with the charging case. Call: Up to 6 hours in Normal mode. 5 hours in ANC mode." Turn on LDAC as well and it drops again — Soundcore gives "LDAC On (ANC On): 5H (Earbuds)/25H (Charging case)". When you do need a top-up, Soundcore's spec is "10 Mins = 4Hrs". That is enough to get through an unexpected meeting or a late-night study session.
Fully Customizable via the Soundcore App#
The companion app is one of the most feature-rich in the budget category. Soundcore lists the EQ feature as "Customized EQ: HearID" — a personalised hearing test that adjusts output to your ear's frequency response — alongside custom EQ profiles, touch-control customisation and a fit test that uses the microphones to verify your ear tip seal.
Multipoint Connection for Seamless Switching#
With Bluetooth 5.2 and multipoint support, the Space A40 connects to two devices simultaneously. Switch instantly between your laptop and phone without the tedious disconnect-and-reconnect dance.
But you cannot have multipoint and LDAC at the same time. Soundcore's own FAQ is blunt about it: "Check if you have enabled LDAC as it cannot be used at the same time as multipoint connection. If you have enabled LDAC, please disable it." So the Hi-Res codec and the two-device convenience are an either/or, and the article's two headline features do not stack.

Pros & Cons#
Pros:
- Adaptive ANC that Soundcore rates at "Reduce Noise By Up to 98%", with a transparency mode
- Soundcore's published playtime is 10 hours in Normal Mode and 8 with noise cancelling, or 50 and 40 with the charging case
- "10 Mins = 4Hrs" fast charging
- LDAC support for Hi-Res Audio Wireless on Android, alongside SBC and AAC
- Wireless charging as well as USB-C, which budget rivals usually omit
- "6 Mics with AI" for calls, rated at up to 6 hours in Normal mode and 5 in ANC mode
- HearID hearing test and custom EQ in the Soundcore app, with a fit test that checks the seal
Cons:
- LDAC and multipoint are mutually exclusive - Soundcore says LDAC "cannot be used at the same time as multipoint connection"
- IPX4 is splash and sweat resistance only - not swimming, not heavy rain
- LDAC is Android-only; iOS falls back to AAC
- Running LDAC and ANC together drops Soundcore's own figure to 5 hours from the buds, half the Normal Mode ten
- Bluetooth 5.2 rather than 5.3
Final Verdict#
Buy it. The Space A40 is the rare budget earbud that genuinely competes upward: Soundcore's "Reduce Noise By Up to 98%" adaptive ANC, a published 10 hours in Normal Mode and 8 with ANC on (50 and 40 with the case), "10 Mins = 4Hrs" fast charging, LDAC for Hi-Res on Android, and wireless charging most budget rivals skip. Two caveats: IPX4 covers sweat and splashes only, and Soundcore says LDAC and multipoint cannot run at the same time.
Our recommendation: Grab a pair now — it is worth buying a second set as a backup or gift. View on Amazon
