If someone does not listen to sports and MP3s, I would recommend this product only. Unfortunately, come to my Bluetooth stereo headset (Sennheiser MM 100) the MP3 songs only mono. Furthermore, I still see a need for development in the mp3 ringtone store and when filing the MicroSD card (unfortunately, because you need a steady hand). If someone can give up a busy schedule and on an Internet connection, the device is just right. Furthermore, I still see in the operation of the Media Player a pent-up demand (such. As create your own playlist). All in all, recommended as a second phone in any case continue to this mobile phone watch. In my phone to a 16 GB MicroSD card is SanDisk and works with the mobile phone watch with me properly.
