Jai personally connected simultaneously, a MacBook Pro, an iPad, an iPhone 5 and Samsung Galaxy S3 at each connection of a device is assigned a color (5 respectively) to be displayed by sector on the pentagon, lorsquun device is connected and transmits an audio file, ALL OPERATING pentagon shows the color assigned to it. What can seem a gimmick initially turns out interesting, it is possible to know (in the case of a family and a number of connected devices) what is the device connected about it just looking at the color displayed.
I got paid an NFC device time to do a test, lappareillage no problem this is simple and effective.
Bluetooth range on a Smartphone / tablet does not exceed ten meters around unless you dispose of a Class 1 Bluetooth device (these are typically dongles (adapters PC or MAC) dune maximum power of 100 milliwatts, their reach is around 100m (barrier-free), it is given for about 90m.
This little device is powered via a micro USB socket and a small power supply unit to the standard US (a French adapter is supplied), you no longer QuĂ connect an amplifier, even denceintes amplified and voila.
To: quality, functionality, compatibility class 1.
Against: for prixrien
Conclusion: I have a similar device from Logitech, much more expensive (excellent incidentally) but which does not allow me dy connect as equipment, a store them as easily. So for the price announced this without being a revolution gives men more (NFC, number of connections) and for me dear, this is my adopted home appreciates old stereo and everyone is counting.
