Wireless or wired: Enjoy high-resolution wireless sound with support for aptX HD and aptX Adaptive, especially when paired with the included BTD 700 Bluetooth® adapter. For maximum purity, connect via USB-C for lossless listening up to 24-bit/96 kHz.
Parametric EQ: Expert-level equalization lets you define frequency bands, widths, and filters to precisely shape your sound. Tailor bass, enhance vocals, or fine-tune for any genre, just like a mastering engineer.
Adaptive ANC & Transparency Mode: Powerful noise cancellation blocks distractions without degrading clarity, dynamics, or balance. Transparency Mode instantly lets in surrounding sounds when you need to stay aware.
Listen for days, not hours: A class-leading 60-hour battery keeps you going through long trips or work weeks. Just 10 minutes of fast charging adds up to 7 hours of playtime, ideal for when you’re on the move.
