Summary: Sennheiser OMX 680i High-performance Clip-on Headset Integrated Remote and Mic is a very good earphone perfectly adjusted in ears, even when jogging. The sound is also perfect and you can hear the noises of the environment.
Summary: I wanted to get some headphones which would enable me to a) hear my music in good quality b) control my iPhone without taking it out of my pocket (volume, advance to next track, answer the phone) c) get a decent fit so that I can wear them when out walking the dog or working in the garden.
Summary: These were one of only a few headsets that seemed to meet my criteria, which were: Over ear hooks; Remote (with both volume and skip/pause/play controls) for my iphone 4; and microphone to take calls (I wasn't asking for much!).
Summary: I bought this headset for using with an iPhone whilst running. I was previously using in-ear headphones and they constantly fell out whilst I was running. These, on the other hand, are rock-solid once attached over the ear, and are extremely comfortable, even at pace.
