    1. The best recorder for sensitivity

      Posted by DT on Jan 19th 2018

      hard to believe the distance from which this recorder picks up voices, does great job at filtering out other (non-voice) sounds

    2. very clear

      Posted by JT on Nov 13th 2017

      very clear recordings, fast shipping

    3. Amazingly clear recordings, crazy long runtime

      Posted by J Stanton on Oct 16th 2017

      Switched to these after using the older diasonic 5300s for years, the speech clarity on the recordings is remarkable, and the gain on that little mic is nuts. Highly recommended for investigative use. haven't used it for memos, etc.
