JBL Live Beam 4 Earbuds Debut with Personalized Audio Learning and Touchscreen Case

JBL has launched the Live Beam 4, premium wireless earbuds that automatically adapt sound based on individual hearing profiles, available since May 2026 for €199.99. The standout feature is Personi-Fi 3.0, an adaptive audio system that generates a personalized sound curve by analyzing each user's hearing characteristics and preferences through an interactive app-based test. This approach allows the earbuds to "learn how you hear," tailoring the audio experience to match the listener's unique auditory profile and the shape of their ear canal.
