Genius has a new product that will turn just about any 3.5mm audio playing device into a wireless streaming system. The device I called the HS-905 BT and it is a little gadget that looks a bit like a flash drive. It has Bluetooth connectivity inside and when you plug it into your normal headphones or speakers and it makes them wireless.
It will plug into any speakers that have a 3.5mm input. The HS-905 BT also has an integrated mic so you can use your headphone or speakers for hands free calls at your desk or the gym. The device comes with a set of headphones too, but you can use any existing 3.5mm headphone with the HS-905 BT.
The drivers in the headphones are 10mm units with 20Hz-20KHz frequency response. The impedance is 16 ohm and the battery inside the adapter charges with USB. The package includes a carry pouch, the charge cable, and a quick guide.
