This is a review of the Sony NW-A45 after couple of week of use. This device is really good for some one who wants to invest in seperate high res audio player instead of playing file in the mobile device.
Short over view is that
1) The physical key has really good tactile feel.
2) The User Interface is easy to get used to and has easy access to common features.
3) DAC feature is a bonus and shows the audio output level and sample rate.
4) Language Study has quiet unique feature that allow to repeat within a audio file in a loop.
6) Battery life is really good and will last more than 20 hours of playback if you are playing Hi Res and CD quality sound.
Downside.
1) Bluetooth need to be paired again while switching devices.
2) Proprietary usb cable
3) Syncing Software takes forever to analyse the songs and get missing information.
