The boAt Rockerz 421 Gen 2 is an over-ear wireless headphone whose official listing specifies 50 mm × 2 drivers, Bluetooth 5.4, IPX4 water resistance and up to 60 hours of playback at 60% volume. Those figures are boAt’s claims, not independent test results. The product page listed an MRP of ₹2,490 inclusive of taxes and showed “Sold out” and “Restocking soon” when accessed on October 3, 2026; check the live listing before buying.
What the Rockerz 421 Gen 2 offers
boAt’s official Rockerz 421 Gen 2 listing describes a wireless headphone with onboard music and call controls, voice-assistant access, and a USB Type-C charging port. Its listed specifications are:
- Drivers: 50 mm × 2.
- Playback: up to 60 hours at 60% volume, according to boAt. The listing does not provide independent test results or fuller test conditions.
- Battery and charging: 600 mAh battery; charging time up to four hours.
- Wireless connection: Bluetooth 5.4.
- Low-latency mode: BEAST Mode, with a claimed 40 ms latency.
- Water resistance: IPX4.
- Dimensions: 171 mm × 79 mm × 197 mm.
The 60-hour figure is a maximum manufacturer claim, not a guaranteed runtime for every listening volume or use pattern. The same qualification applies to the stated 40 ms latency: boAt lists it as a product specification, and no independent measurement is established here.
What comes in the box
boAt lists one headphone unit, a user guide, an AUX cable and a Type-C charging cable in the package. The included AUX cable provides a wired listening option; the listing does not specify additional model-specific replacement parts.

Do not confuse it with the Rockerz 421
The Rockerz 421 Gen 2 is distinct from the separately listed boAt Rockerz 421. boAt’s support page for the Rockerz 421 gives that other model 40 mm × 2 drivers, up to 40 hours of music playback at approximately 60% volume, a 400 mAh battery and a two-hour charging time. Those specifications do not describe the Gen 2.

What to check before choosing it
- Compare the playback rating using its stated condition—up to 60 hours at 60% volume—rather than treating it as a universal runtime.
- Check whether Bluetooth 5.4, USB Type-C charging, IPX4 resistance and the claimed 40 ms BEAST Mode match your needs.
- Confirm that an AUX cable and Type-C charging cable are included in the package you are buying.
- Verify live price, availability and warranty terms for your location; the official listing’s MRP and stock status may change.
