The headset is flunked me because I could not use my headphones S4 Mini couple because the mobile headset simply not found. Even my computer and the cell phone my wife did not find the headset. So a replacement unit ordered, thanks to Amazon super fast as well with no problems upon return. However, even in this earphone, the same problem. Is not to be found as a Bluetooth headset. Without further ado, my friend and also could not find the headset. We tried three different cell phone's, a Kindle and two computers. All did not find the headset. Then I happened to come true in the media market and since the same headphones was again and also because the same problem. The friendly seller wanted to help me and we have then tried about 4 devices in the media market all could not find the headset. From me so do not buy recommendation. Property me then at Amazon ordered the deleyCON SOUND TERS Bluetooth Headset and immediately all the devices I have no problems find the headphones and the way is really great (5 stars). Guess that because a defective production of Philips in circulation is different because you can not explain. I hope I could help you in your buying decision. Greeting Jochen
