The Philips Bluetooth adapter has clearly exceeded my expectations. This I have connected to a high-quality hi-fi system and thus play MP3 music in the highest resolution or videos from my phone off. It is opposite a cable connection no noticeable loss of quality. Simply a super sound in spite of Bluetooth. The range is my cell phone up to 13 meters. With greater distances, disturbances occur in the transmission. This adapter facilitates the connection between Bluetooth players and a stereo system already significantly since you not only must put up with any leads, and you therefore also has no tripping hazards.
