Can look very sophisticated. Is either of metal or thick coated with metal and accordingly "difficult". Connectors for Micro SD card, smaller USB connector (or antenna for radio reception) and plug. Probably all This should be covered in "modern" connectivity. Bluetooth connection works immediately. Sound, class, nice bassy and good loud. This allows some excellent sound, for example placed in the hallway; o). A tiny bit too much treble. You notice but only if you fully turned up on the particle or Classical / audiobooks. Then there is something to rauschig / light but at least no clatter. But call was not so outstanding and rauschig own echo for callers. While speaking directly into the microphone was a bit better, the Hall remained, however. However, I as a listener have the caller super good and clearly understood.

One just has no display, white / so do not look at what is currently selected (which mode and what / r radio station / frequency). 1 button also has unfortunately several functions (longer / shorter press). I verheddere me before you. Forward is for example at the same time turn down the volume. But at least all of the functions are arranged around and logic and no one under the appliance. The announcement (on power) is extremely loud (because I twitch fully together each time), the sound setting was no matter how loud / quiet beforehand. Practical storage box - above the device down cable and manual.
