The boAt Rockerz 421 Gen 2 is an over-ear wireless headphone whose official listing specifies 50 mm drivers, Bluetooth 5.4 and up to 60 hours of playback at 60% volume. That runtime and its 40 ms BEAST Mode latency are boAt claims, not independently verified test results. The product page listed an MRP of ₹2,490, inclusive of taxes, and showed the headphones as sold out with restocking soon when accessed on October 3, 2026.
boAt Rockerz 421 Gen 2 specifications
These details come from boAt’s official Rockerz 421 Gen 2 product listing. Playback and latency figures are manufacturer claims; the listing does not provide independent test results.

| Playback | Up to 60 hours at 60% volume; a manufacturer-stated maximum |
| Battery and charging | 600 mAh battery; charging time up to four hours; USB Type-C charging |

What the 60-hour battery claim means
boAt says the Rockerz 421 Gen 2 offers up to 60 hours of total playback, with the product listing attaching that maximum to 60% volume. “Up to” describes a maximum rather than a guaranteed result for every listener. The listing does not give fuller test conditions or independent runtime measurements, so actual playback may differ with volume and use.
The listed 600 mAh battery has a charging time of up to four hours. That is the stated charging duration, not a claim that the headphones deliver a particular runtime after a shorter charge.
