Device from the idea brilliant. Fits super ear ideally go for listening to audio books. Unfortunately, only modest series consistency. Have 3 units purchased and coupled with i-phone 6 and iPad mini with retinas (works immediately, no access code required). One of the devices is combined, but transmits nothing but calls Siri to connect two devices and transfer after the beginning for 1-2 minutes first prevails extremely smooth transmission quality, stabilize the transmission and works well. More is not to be expected from the low production in Hog Kong in the price or is it? Too bad, otherwise it would definitely 5 stars
