Summary: Wonderful product. I earlier had 'Philips SHS8100/98 Earhook Headphone' which were good but did not have microphone. This one has microphone as well. Since its in-ear and fits over the ear, I can use them on my bike while wearing my helmet and it doesn't fall off. Sound quality is good. It says that its water resistant and can take some load etc, although I haven't tried that.
Summary: I had the earlier model which lasted for more than 1 year of daily 12 Km runs in all weather types including rains. It was excellent. But this model, seems a little different in terms of the ear fit. After sweating a little or some rain, it starts slipping out of the ears so it ruins the run as every 10 seconds you have to push back in the ear buds.
Summary: The sound quality is really poor - very low volume so not useful in the gym at all, unless you want to talk while listening to music. The design style and comfort is very good but sadly the sound doesn't match.
