■ The catch — co-equal billing, always
The battery is short. Just 6 hours per charge (24h with the case) — the shortest here — and IPX4 means sweat-resistant, not waterproof. Great indoors; a poor fit for long or wet outdoor runs.
Dealbreaker? Runner-up №1 nearly doubles the battery with an earhook fit ↓

ANC blinds you to traffic
Sealed noise-cancelling earbuds hide the cars you can't see — on roads with traffic, ANC is a genuine safety risk. Choose transparency mode, open-ear, or bone-conduction designs so your ears stay aware.
IP ratings don't last
A water rating is a one-time lab test, not a lifetime promise — chlorine, saltwater, and heat break down the seals, and none of these are swim-rated except the IP68 models. Don't treat sweatproof as waterproof.
Promo-price whiplash
Budget sport earbuds from JBL, Soundcore, and JLab swing 15–30% on Amazon promotions — the price you see today can jump next week. Buy on the street price, not the MSRP.
