The boAt Immortal Airspeed Pro follow a true wireless, in-ear design with no cables, neckband, or wingtips, keeping the form factor straightforward and unencumbered. They feature stereo speakers and carry an IPX4 rating, meaning they are resistant to sweat — a practical consideration for active use. The earbuds do not include RGB lighting, a UV light, or any display element.
The boAt Immortal Airspeed Pro use 10 mm driver units and cover a frequency range of 20 Hz to 20,000 Hz. They rely on passive noise reduction rather than active noise cancellation, so there is no ANC circuitry involved. The earbuds do not support spatial audio, Dolby Atmos, or Dirac Virtuo, and they do not use a neodymium magnet in their driver construction.
Each earbud carries a 40 mAh rechargeable battery rated for 8 hours of playback, while the 380 mAh charging case extends the total to 32 hours. Charging is handled via cable and takes just 0.5 hours, though wireless and solar charging are not supported. A battery level indicator is built in, so checking remaining charge is straightforward without guesswork.
The boAt Immortal Airspeed Pro connect wirelessly via Bluetooth 5.3 with a maximum range of 10 m and a rated audio latency of 40 ms. The codec support is limited to the standard SBC baseline, as AAC, LDAC, LDHC, aptX, aptX HD, aptX Adaptive, aptX Low Latency, aptX Lossless, and aptX Voice are all absent. Similarly, Bluetooth LE Audio, Auracast, NFC pairing, and fast pairing are not available. The case charges over USB Type-C, and the earbuds can also be used in a wired context for charging purposes, though all audio transmission is handled wirelessly.
The boAt Immortal Airspeed Pro support fast charging and can function as a headset, with controls placed directly on the earbuds and voice prompts to assist with navigation. A mute function is also on board, though there is no in-line control panel, in/on-ear detection, ambient sound mode, notification reading, find-device feature, temperature sensor, or camera remote function. A travel bag is included in the box, and the earbuds come backed by a one-year warranty.
The boAt Immortal Airspeed Pro include a noise-canceling microphone, which works to reduce unwanted background noise during calls and voice input.
