Our Verdict
Anker Soundcore Space A40 Truly Wireless
EarFun Air Pro 4+
The EarFun Air Pro 4+ and the Anker Soundcore Space A40 Truly Wireless are close competitors, but the Anker are better value for most people. The Anker's ANC is more effective overall, and their battery lasts much longer, which makes them easier to recommend for commuting and flights. The EarFun pull ahead in a couple of other areas, though. They have a slightly better mic and support a wider variety of codecs. Unless you're certain you need those codecs or are dead set on a stemmed design, the Anker are the way to go.
