Roland R-07 black

At its core, the Roland R-07 delivers the same excellent sound quality for recording and playback as its predecessor, the R-05. It also weighs approximately the same and has very similar size. Even though its body is all plastic, versus the R-05's metal housing, it feels good in the hand due to its rounded corners and rubberized surface.

The R-07 features a built-in speaker, unlike prior models. Therefore, it comes as a major disappointment that the speaker, even when set to its maximum volume, is too quiet to be of any use for monitoring vocals.

Bluetooth, which is another new feature, works well as far as connecting to bluetooth-enabled speakers and headphones. Connection is quick and stable, and sound quality is excellent. Automatic re-connection when turning the recorder back on is a great feature.

However, I have experienced several glitches where the recorder froze up during playback of certain files, which required restart.

When starting up, the recorder initially says "No SD-card," and it takes a moment for the device to recognize the card. In one instance, the micro SD-card was not recognized, requiring reboot. Furthermore, I find it impossible to remove the micro SD-card by hand, tweezers are needed.

The remote connection sometimes works, sometimes doesn't (with android 8.1.0.) With an android 5.0 device the remote connection worked fine. But I can't really trust it to work so it's a no-go.
I'm also wondering why you can't move the files remotely. You can listen and browse them kind of, with the app. The audio does not stream to your phone/tablet at any point, you need to connect headphones to the R-07.

I didn't like the app. It's not a good app appwise.
