I have been seeing this neckband being worn by many. I see them on the train, on the bus, and on the streets. It had become fashionable and so I wanted to have one. I got this HX1200 model. What I like with this neckband is that it is neat. No messy wires since these are retractable and easy to manage. Therefore, it is neat. It pairs very easily with my iphone at HX 1200 bluetooth setting. The stereo sound is great. More so with its noise cancelling feature. When fully charged, I can play music for up to 12 hours. And when I am getting a call, this headset vibrates to alert me. So far, I am enjoying this electronic device.
