Our Verdict
Anker Soundcore Space A40 Truly Wireless
JBL Vibe Buds True Wireless
The Anker Soundcore Space A40 Truly Wireless and the JBL Vibe Buds True Wireless are both budget-friendly earbuds. The Anker, however, is positioned as a value-driven brand with active noise cancellation (ANC), which the JBL lack. However, the JBL buds have a better mic, longer battery life, and a brighter treble response, which you may prefer. However, you can still use the EQ on the Anker to alter the tuning to your taste.
