boAt Nirvana Crown Review: TWS with Revolutionary Case Controls

Innovative Design & Controls

The boAt Nirvana Crown stands out with its Sonic Arc case featuring a patent-pending rotating crown. Unlike conventional TWS cases, this offers tactile volume control through haptic feedback that intensifies when increasing volume and softens when decreasing. The case includes programmable multi-color LEDs that display battery status (100% shown when fully charged) and notification alerts. A triple-press locking mechanism prevents accidental adjustments—press the crown button three times, holding the last press to disable controls completely.

Audio Performance & Tech
