I've tested dozens of earbuds over the last year - these blow them all out of the water

This review lauds the $249 Denon PerL Pro earbuds for delivering accurate, spacious, and vibrant sound straight out of the box—rivaling over-ear wired headphones—without needing app-based EQ, and highlights features like Masimo AAT personalization, Dirac Virtuo, aptX Lossless, eight microphones, customizable touch controls, IPX4 resistance, and up to 8 hours of battery life with three extra case charges; while not intended for workouts due to cost, proper ear tip fit is emphasized, and the reviewer deems them a new benchmark in earbuds across multiple music genres.
