Review: Sturdy metal construction great sound and up to 32gig micro SD card(not included) storage. - I purchased this recorder recently from desertcart as I wished for both Bluetooth connectivity and FLAC type recording. I was very familiar with this design recorder as I also own their fine DM-720 which uses the same NiMh battery type with USB charging and built-in USB plug. The info on desertcart is not quite correct as there is only one battery needed and included that being their proprietary 1.2v 750ma NiMh rechargeable battery. My older model also uses the same and both have long battery life. This LS-P4 also comes with a 5mm to 1/4-20 camera thread adapter if used on a tripod. The BT function was easily setup and paired with my Android app Audio ctrlBT Olympus App. Connection is fast and accurate however; if you chose any of the three recording formats PCM(wav),FLAC,or MPS, the remote app only has use of the PCM format and not the other formats.One other issue encountered with this fine recorder and by comparison to my Olympus DM-720 in similar design is the Red "Record" button. My only issue is that it does require a double press of this button in order to begin recording. The first press "sets up" the record for a quick visual of settings but, you must press it again to record. This process may catch you off guard in a fast record situation as you have to insure that the screen says "record", and not "pause". This is different as stated compared to many other makes and models when there is only a single press for record. Not an issue for me when I remember this fact.I have tested the remote app up to 30 feet,no problems and it works fine. Remember to disconnect the BT feature when done and to reset your format to FLAC or MP3 as it remains in PCM even after disconnecting from the remote app.
Review: Great Recorder for Quick and Easy Nature Recordings in Field - This is a great recorder, period. I bought it after using a 15-year-old Sony that is not capable of a fraction of what this recorder can do. This recorder is very small and lightweight, yet it boasts features and options previously found only on much larger and more costly recorders. I tested the LS-P4 this morning in the field for bird and other nature recordings. The microphones are very sensitive, and the adjustable recording level, quality, format, and zoom-mic features are very helpful for field recordings. The menus are easy to learn and use. Time will tell if the built-in USB connection will hold up well. I hope so - now that I've used the LS-P4, I would not want to do without it. Highly recommended, along with a download of Audacity.
