Verdict

The boAt Rockerz 400 is a lightweight, 124g on-ear wireless headphone featuring 40mm dynamic drivers that deliver a bass-heavy 'Super Extra Bass' sound profile across a 20Hz-20KHz frequency range. It offers dual connectivity via Bluetooth 5.0 (with a 10m range) and a 3.5mm AUX port, powered by a 300mAh battery that provides up to 8 hours of playback on a 2-3 hour charge. Key pros include its foldable/portable design, integrated ear-cup controls for calls and media, and high value for its budget price. However, notable cons include an unadjustable headband that can feel tight, lack of fast charging, and an on-ear fit that some users find uncomfortable or painful during extended listening sessions.
