Verdict

The boAt Rockerz 421 is a wireless over-ear headphone featuring 40mm dynamic drivers that deliver the brand's bass-heavy Signature Sound across a 20Hz–20kHz frequency range. This 2025 model utilizes Bluetooth v5.4 for stable connectivity and includes a dedicated BEAST Mode that reduces latency to just 40ms, making it highly suitable for gaming. For communication, it is equipped with an ENx technology-enabled microphone designed to filter out environmental noise for clearer calls. Key pros include a substantial battery life of up to 40 to 60 hours, an adaptive and foldable design for portability, and support for dual pairing and voice assistants like Siri and Google. On the downside, the device lacks active noise cancellation (ANC), and some users may find the non-adjustable headband tight during long listening sessions.
