The EarFun Air Pro 4 earbuds cost $53.16 at Amazon as of October 23, down $26.74 from their $79.90 full price.
That is a cut of about 33%, and it lands $2.65 above the lowest-ever price the listing cites, $50.51. Amazon has been slipping discounts onto various models ahead of Black Friday instead of saving them all for the day itself. The listing also calls the Air Pro 4 its pick for best budget earbuds, so this is a recommendation built on an earlier verdict, not a fresh review.
The listing says the earbuds use adaptive ANC (active noise cancellation, where microphones detect outside sound and cancel it out) that blocks up to 50dB of noise. It lists battery life of up to 11 hours per charge, stretching to 52 hours with the charging case. It also quotes its own earlier review, which said the earbuds "can adeptly handle a multipoint connection, feature a well-rounded sound profile with variation thanks to the in-app equalizer," and "offer manually adjustable ANC, which isn't even a given on premium noise-canceling earbuds." Multipoint means staying connected to two devices at once, say a phone and a laptop.
The practical question is whether to wait. By the listing's own numbers, a buyer who holds out for Black Friday could save at most a few dollars unless the price breaks through its previous floor. That makes today's price close to the best case on record.
The spread is also worth a look. A $79.90 full price that has been undercut by $29.39 at its lowest point reads less like a benchmark and more like a ceiling.
