I have purchased the product in order to equip my car stereo, which has input on a 3.5mm jack with Bluetooth. I for almost a year with me pursuing it now in the car and always had a stable connection. Normal listening music via Bluetooth works just as well as to call it. Here, the microphone is integrated in the device, my opponent understands me at all times well. To answer and to end can be easily operated of the device button. Music also can be paused and continued About. On the top are still two button for backward and forward navigation of songs, this also works for every point perfectly! Therefore I can only express a strong buy recommendation for this device!
