Attention, first of all, the following notice: The Sony clock radio works ausschließich (!!!) with an iPhone 5 or iPod 5, which is not shown in the above product description so. Hence the warning to all who hope to use the device with a previous iPhone / iPod version: This is not possible. But now to the device itself: Upon opening the package will first be slain by manual in all possible languages, which are also as small and compact folded. That is: A lot of paperwork, which is actually not necessary, since the start-up and operation is quite simple and self-explanatory. Once the clock radio is powered, it automatically displays the right date and the right time. The clock was a few minutes ago, but everything else was correct. Once you have set an appropriate frequency, one can even listen to the radio. The sound is good. The sound with an attached iPhone is fine, but not outstanding. Since the device is indeed intended primarily as an alarm clock and not as an amplifier or the like, but that is still bearable. If you want to use the clock radio mainly as iPhone docking station in order, for example at a party playing music, one should resort to another device that produces a better sound. Of course it is also possible to be woken up with his favorite radio station or a simple beep. All this can be adjusted as desired. There are two alarm set, which is very convenient when the alarm by two persons is used. In addition, you can set, for example, that you will be woken up at the weekend at a different time than on weekdays. So it will save you an arduous changing the time before bedtime. The brightness of the display can be adjusted. This is good because the preset brightness at night is a bit irritating when you're normally accustomed to no light source of its kind. The appearance of the device is also good, looks nice and is quite compact. The cable is long enough, if you want to set the alarm clock on the bedside table. Overall, a good device, even if the sound with iPhone / iPod could be a bit better.
