Bought these to replace my old Etymotics ER5is which are no longer made. Third pair so that tells you how much I like them. I wear them most of the time on my motorbike either just as ear defenders or to listen to music on boring runs. There is a choice of ear fitments with them so you should find something comfortable - all ears are very individual! You can also go to an approved ear clinic and get made to measure fitments - might do this if I ever have the time/money. My first two pairs wore out through a bike related issue - the cables frayed in the wind, rubbing against my leathers. I now take more care routing the cables so they might last better. Sound reproduction seems fine to me - I can hear music clearly at motorway speeds. I couldn't tell you whether they are technically as good as a more expensive set but they are good enough for my purposes. They are reasonably priced by my reckoning - you get your moneys worth.
