Verdict

The Fire-Boltt O-Prime is an over-ear gaming headphone featuring powerful 50mm dynamic drivers, Bluetooth 5.3 connectivity, and a dedicated gaming mode with an ultra-low 28ms latency. Its standout characteristic is an exceptional 100-hour battery life on a single charge, complemented by a built-in cardioid microphone for clear communication and a dual-mode design that supports both wireless and wired AUX connections. Main pros include its extreme endurance, stable low-latency performance for competitive play, and a comfortable, feather-light build with convenient wheel-based volume controls. However, notable cons include the lack of active noise cancellation (ANC), the absence of dedicated buttons for changing music tracks, and a build primarily composed of plastic.
