The Beats Acoustic Engine makes your listening experience intimate, personal, and real. Our signature DSP software is designed to generate the emotional experience that Dr. Dre, Jimmy Iovine, and some of the music industrys greatest rock, hip-hop, pop, electronic, and R&B producers want you to feel. Silence the noise from your daily commute or the drama from your loud neighbors with our no-compromise dual-mode Adaptive Noise Canceling. Dead batteries can kill your vibe in a flash. The New Beats Studio3 fixes this with a 22-hour rechargeable battery. Turning Pure ANC off for low power mode provides up to 40 hours of playback without sacrificing audio quality.
