The boAt Nirvana Crown are feature‑packed true wireless earbuds designed to deliver premium sound performance and smart usability at an accessible price point. They use dual 10 mm dynamic drivers that work with Hybrid Active Noise Cancellation (ANC) — capable of reducing up to ~50 dB of ambient sound — giving you a more immersive listening experience for music, video, or calls. The inclusion of spatial audio further enhances the sense of depth and clarity in sound, making content feel more engaging and detailed. Connectivity is modern and stable with Bluetooth v6.0 and multipoint pairing, so you can easily jump between two devices like a phone and laptop without repeated reconnections. One of the most innovative aspects of the Nirvana Crown is its interactive charging case featuring the SONIC A.R.C (Advanced Rotational Crown). Instead of just a power reservoir, this case acts as a control hub: a rotational dial lets you adjust volume, control playback, and take calls without touching your phone. It also has haptic feedback and LED indicators that visually reflect actions like volume changes or status updates — a rare and intuitive feature in TWS earbuds. The case can even act as a remote shutter for your smartphone camera on compatible devices.
