Review: Easy to use and good speakers - Excellent for recording, easy to use and good speakers.
Review: It Just Keeps Getting Better - This is the fourth Olympus Digital Voice Recorder I’ve purchased, and they just keep getting better. I have and still use the older DM 520, but I wanted the DM 720 as a backup. After using the DM 720, the older one has become the backup. The new DM 720 is lighter than its DM 520 predecessor; it has a simpler and more efficient design, and it’s easier and more convenient to use, and it only takes one AAA battery instead of two. I’m guessing that only requiring a single battery instead of two is due to technological improvements in the device which require less power to operate. Indeed, this device is still like a miniature recording studio, and it has advanced with the times. The DM 720 comes with a built-in USB connector plug, which can be a little awkward to use because it’s hard to see the tiny screen when it’s plugged in to the PC. But when connected to your PC, it serves the dual purpose of charging the battery, and allows you to easily manipulate the files and to transfer them back and forth from the PC. Olympus should have provided a USB adapter cable AND an adapter for outlet charging, but we can forgive them these oversights since the unit really is a marvel of engineering and design. On the DM 720 there are only two major areas available for holding content, and these are the Recording section, and the Music section. The Recording section retains the usual 5 (A-E) areas for external audio recordings, with a maximum of 200 files for each letter. The unit has not just two, but three microphones built-in, with the usual high quality audio and an abundance of features. The Music section handles any and all audio content superbly, as to be expected. I have several audio books, and when I transferred them and other personal recordings to the unit, it quickly filled up the 4 GB internal memory capacity of the unit. I then bought a 32 GB micro SD Card (which fits in a slot in the battery section) to handle all the books, plus any future ones that I acquire, and all my music. The User Guide indicated that the micro SD card required formatting, but it accepted audio files and recordings immediately without such formatting. Apparently the DM 720 is not compatible with Audible Books (the one owned bydesertcart), and that was disappointing. Aside from that shortcoming, this is still a sweet, versatile, and powerful little device very worthy of your consideration and purchase.

### ⭐⭐⭐⭐⭐ Very useful
*by C***R on January 7, 2025*

My first camera was an Olympus so I was confident buying this. It is thin , almost weightless, and records beautifully. I bought it to speak my travel journals because my handwriting is so bad even I can't read it. It does MUCH more than what I use it for. I found online software that turns the voice into text. I can use it on a bumpy ride or anywhere. For the price, it is perfect for me. I bought a hardshell case for it.
