Anker Soundcore Space A40 vs EarFun Air Pro 4
Quick take: The Anker Soundcore Space A40 costs $15 less; the Anker Soundcore Space A40 lasts longer per charge (8 hrs).
Which one to buy
These are two of the earbuds owners name when someone asks for cheap ANC, and they're closer than the $15 gap suggests. Each has adaptive ANC, LDAC, multipoint and a wireless-charging case with roughly 50 hours total. The difference is what each one adds on top. The Space A40 adds comfort: small, flush shells that side-sleepers and helmet wearers seek out, and a 10-minute charge that buys four hours. The Air Pro 4 adds connectivity: aptX Lossless for Snapdragon phones, LE Audio and LC3, Bluetooth 5.4 against the A40's 5.2, and in-ear detection, which the Soundcore lacks.
On ANC, owners rate the EarFun a little above same-priced Soundcore rivals for engine rumble. The A40 still holds up against buds that cost two or three times as much for low-frequency drone. LDAC hits the A40's battery hard, dropping it from 8 hours to about 5, whereas the EarFun is rated at 7.5 hours with ANC and owners say it meets that. The EarFun's sound comes heavily bass-boosted and needs a trip to the EQ.
Both have flaws owners keep raising, and they're different ones. The A40's touch controls skip volume until you remap them in the app, and some owners hit a one-bud battery-drain failure after the first year. The Air Pro 4's transparency mode hisses enough that many owners turn it off, and the case is glossy and slippery. Calls are poor outdoors on both. Neither is a buy for someone who takes calls on walks.
Anker Soundcore Space A40
If you want to sleep, ride or wear buds for long sessions, or you're on an iPhone, where the EarFun's codec lead disappears and the A40 is $15 cheaper.
EarFun Air Pro 4
Best if you have a Snapdragon or LDAC-capable Android phone and want the most codec support under $70, along with in-ear detection, Bluetooth 5.4 and a 7.5-hour ANC battery owners say meets its spec.

Anker Soundcore Space A40 vs EarFun Air Pro 4: common questions
Is the Space A40 or the Air Pro 4 better for sleeping on your side?▾
The Space A40. Owners specifically praise how flush its shells sit, and side-sleepers report wearing it on a pillow comfortably. The Air Pro 4 fits securely for most people, but nobody singles it out as a sleep bud.
On an iPhone, is the EarFun worth $15 more?▾
Probably not. On iPhone both use AAC, so the EarFun's main selling points, aptX Lossless and LDAC, go unused. What you'd still get is in-ear detection and a newer Bluetooth version, against the A40's smaller shell and lower price.
Does LDAC cut the Space A40's battery more than the Air Pro 4's?▾
On the A40 it noticeably does, cutting ANC playback from about 8 hours to roughly 5. No LDAC-specific figure is documented for the Air Pro 4; owners only confirm its 7.5-hour ANC rating holds up in daily use.
Are the Space A40 or the Air Pro 4 any good for phone calls?▾
Neither does it well. A40 owners say people struggle to hear them outdoors, and Air Pro 4 owners describe the mic falling apart in wind even at walking pace. Both are fine at a quiet desk.
