Talks are fine, but I don't find them to be anything special. As far as I can tell, the drama track is as it was broadcasted on the net radio. It introduces Shouko, voiced by Inoue Marina. She'll be, well, closely related to Camera-chan (Tsutako), eventually. There's more to come, of course.
Microphone is either set up badly, or is low-quality, causing clips. It's stereo, though, unlike most other radio CDs. Kugimii is on the left, Itou-san on the right, and Ueda-san in the middle. Note drama portion is perfectly fine, although it's monaural (5-stars+).
First-pressing comes with a small postcard with the same art as the CD cover. It's small because it has to fit inside a CD case. I wonder if it's usable as a postcard.
