This is very compact but has excellent features; with the SD card there is plenty of storage. Sound quality is very good and the interface is clear an easy to navigate. I haven't had this long enough to be able to comment on durability, but with a Sony product I expect good quality construction. The only minor problem so far is that I haven't been able to connect to Bluetooth headphones; I have tried more than one pair but without success. It is, however, no problem to use them with a wired connection. It may be that I am missing something in the setup process. I still feel that this is worth an 'excellent' rating for the design, storage and sound quality.
