See video on Amazon.com First, beware! if the top -parleurs Creative T4 are announced without son is not entirely true, there are son between the subwoofer and the speakers, son that you see no picture on the presentation, nor on the Misleading packaging box ... ... I expected a wireless system and was therefore disappointed by discovering the product. The only aspect "wireless" is the ability to connect the central box via Bluetooth to many devices with them also to the same function, of course. That said, the Bluetooth connection works perfectly well and I could easily connect and trouble Imac and 2 "smartphones" from different brands. Numerous connection options: -NFC -Bluetooth -Digital (optical input) -Entrance AUX-in / Headphone Pregnant Creatives T4 are equipped with Multipoint technology to simultaneously connect up to two devices to your smart Creative. The Audio control panel that allows the Bluetooth and NFC receiver connection is equipped with a headphone jack, so you do not have a wireless headset. A remote control can manage remote sound. All necessary cables to connect your not equipped with Bluetooth devices, are provided. The connections and operation are simple and the Creative T4 system offers a surprising sound, good quality with powerful bass, payable at the back of the box (single set point) if you do not want to take off! Impressive for its small size. Side look I find it all pretty outdated and trivial; if it was wireless I could have a little stash in the room ... shame In conclusion, a very good all pretty simple in its operation, with very good sound quality resulting in frenzied dance sessions in the kitchen, with a price maybe a little high but certainly because of its Bluetooth connection
