EarFun Air Pro 4 vs Anker Soundcore Space A40 Earbuds

Both are strong value ANC earbuds, but they suit different shoppers. The EarFun Air Pro 4 is the newer, more feature-dense pick: Bluetooth 5.4, aptX Lossless, LDAC, Auracast and a 10-band EQ app, with longer stated battery (11 hours buds, 52 with case, ANC off). The Soundcore Space A40 is the safer, more comfortable all-rounder with adaptive ANC that owners rate as effective, a proven fit, wireless charging and an 18-month warranty. Reviewers praise both for sound; the EarFun wins on codecs and battery, the Soundcore on fit consistency and ANC real-world results.

  • Choose the EarFun Air Pro 4 if you want the latest Bluetooth and lossless codecs, the longest battery, and a detailed EQ, and you have ears that fit standard tips.
  • Choose the Soundcore Space A40 if you want dependable adaptive ANC, a comfortable fit for smaller ears, wireless charging and a longer warranty.
