The original headphones for active music lovers are back - and they're better than ever. Designed to stay put and motivate you with powerful sound, Beats Solo 4 on-ear headphones have been redesigned to deliver incredible, high-fidelity audio, now featuring Personalized Spatial Sound with dynamic head tracking for truly immersive listening. The ergonomic design was developed with comfort and a secure fit in mind, starting with how light they are - weighing just 217 grams, you'll almost forget you're wearing them. UltraPlush ear cushions are designed to be durable and soft, with a soft feel for all-day comfort, to match the impressive battery life of up to 50 hours.
