Designed for discreet everyday recording

The Q91 is designed for unobtrusively capturing audio in professional and educational settings — lectures, meetings, interviews and conversations. The pen writes normally while recording, and the one-button operation with wire control keeps usage simple. Lossless PCM recording at 512Kbit (upgradeable to 1536Kbit) provides clear audio capture, while voice-activated recording at a 50dB threshold avoids recording silent periods automatically. Curated by Aetheo for practical utility.

Key features

Lossless PCM recording with voice-activation

Records in lossless PCM WAV format at 512Kbit as standard, with an option to increase to 1536Kbit for higher quality captures. Voice-activated recording at a 50dB threshold starts and stops automatically with ambient sound, reducing silent passages in recordings.

15-hour continuous recording, 30-day standby

The 180mAh battery provides approximately 15 hours of continuous recording per charge, with 30-day standby. A charging time of approximately 2 hours via the included Micro USB cable restores full capacity.

128GB storage with auto split-recording

The 128GB internal capacity stores approximately 90 hours of recorded audio. Automatic split-recording manages file sizes for easier organisation and playback. The device also functions as a Micro USB flash drive for file transfer to a computer.

MP3 playback with wire control

The Q91 plays back MP3, WMA and WAV files via the included earphone, with wire control for easy in-ear operation. The LED indicator shows playback and recording status.
