SONY ICD-SX77 Digital Voice Recorder

Close to CD sound quality - the newly developed STHQ mode supports up to 20kHz, achieving recording quality close to that of a CD. A 10mm large-diameter microphone is optimally positioned at the best left and right angles to enhance recording effects, capturing more natural stereo sound. It has a capacity of 1GB, with recording times varying by specification: (Stereo HQ) 17 hours 25 minutes, (Stereo) 46 hours 05 minutes, (Stereo LP) 88 hours 45 minutes, (SP) 140 hours 35 minutes, (LP) 374 hours 55 minutes. Additionally, it can play MP3 files. Its dimensions are 30.8×119.3×14.9mm, and it is powered by two AA batteries or the included adapter. I estimate this device could be used by spies. Its price is around RMB 1714. It is not yet available on the market and will be launched on March 16th.
