72GB Wireless Mic Recorder

Built for mobility and endurance, this recorder measures 12.5 × 5.2 × 2.3 cm (±1–3 cm) and weighs ~150g, with a sturdy plastic body. Total storage reaches 72GB via 8GB internal memory and an included 64GB TF card — sufficient for up to 5,000 hours of voice recordings. Its 700mAh battery supports 40 hours of continuous recording and charges fully in 2.5 hours; low-power auto-save ensures recordings are preserved even as battery depletes. Audio performance centres on 1536kbps PCM recording, augmented by DSP noise cancellation and a 360° microphone array that renders speech with exceptional presence and tonal accuracy. Voice activation is highly customisable, with seven sensitivity levels — set to ‘off’ by default — allowing users to match detection thresholds precisely to ambient conditions. Two wireless microphones operate autonomously within 10-metre range, each with its own RF channel and noise-dampening sponge — reducing environmental bleed and ensuring speaker isolation. All core functions — start/stop recording, save, playback — are executed with single button presses, minimising operational friction in demanding real-world applications like seminars, depositions or field research.
