Went around all HK and only found one shop selling this Bluetooth Audio Adaptor. Most shops tell me such a device is extinct as almost ever computer and handphone has bluetooth built in now. One sales lady even told me to try Singapore, like that is where you find extinct gadgets but not in HK.
Any case i bought this for HK220. Not cheap. It works as it should on the iphone and allows me to control the audio volume on the IS800 now. But as you can see it is only 2 black strips, meaning it does not allow for mic or other controls on the headset. So no pause and start any more. This make it even more hassle to use actually. I did see online that there are iPhone/iPod connector adaptors that will not need charging as it uses iPhone power, and allows for calls (through mic) and music control (volume and start, stop only). But i dont see it around in HK.
Any case another reason why i decided to buy this is because i can use it on the trackmill in the gym. So i no more need to jog on the trackmill with a wire running form the machine to my ears if i want to watch the Tv on the monitor.
Technically, it works for all audio devices like TV, iPods and Car stereo (if there is a 3.5mm jack) if i want private audio.
