The boAt Rockerz Prime 255Z adopts a neckband design with in-ear fit, offering a wired connection between the two earbuds while keeping the setup free of additional cables to a device. It carries an IPX4 rating, making it sweat resistant and suitable for use during physical activity. The earbuds feature stereo speakers but do not include wingtips, RGB lighting, a display, or UV light functionality.
The Rockerz Prime 255Z covers a standard frequency range of 20 Hz to 20,000 Hz and supports spatial audio for a more dimensional listening experience. It relies on passive noise reduction to limit ambient sound rather than active noise cancellation, which is not included. Dolby Atmos, Dirac Virtuo, and a neodymium magnet are absent from this model.
The Rockerz Prime 255Z is equipped with a rechargeable battery rated for 50 hours of use, and a built-in battery level indicator lets users keep track of remaining charge. Charging is handled via a wired connection, as wireless charging is not supported, and there is no solar power option on this model.
The Rockerz Prime 255Z connects wirelessly via Bluetooth 5.2, with a maximum range of 10 meters and an audio latency of 65 ms. It charges through a USB Type-C port, though fast pairing and NFC pairing are not available. The earbuds do not support any aptX codec variants — including aptX, aptX HD, aptX Adaptive, aptX Low Latency, aptX Lossless, or aptX Voice — nor do they include LDAC, LDHC, AAC, Bluetooth LE Audio, or Auracast.
The Rockerz Prime 255Z supports multipoint connectivity for up to two devices simultaneously and can function as a headset for calls, backed by a mute function and voice prompts for hands-free feedback. An in-line control panel and an on-device control panel are both present, keeping playback and call management accessible without reaching for a phone. Fast charging is supported, though a travel bag is not included with the earbuds. Features such as ambient sound mode, in-ear detection, a find device function, notification readout, a built-in translator, a body temperature sensor, and a camera remote control are not part of this model.
The Rockerz Prime 255Z includes a single noise-canceling microphone, designed to reduce background noise during calls and voice interactions.
