Just purchased a pair of the Etymotic HF2's.
Excellent bit of kit. Don't listen to the people who say theres no bass. My head shakes with the bass
Most people think there is less bass because these earphones are so clean. Cleaner bass, less distortion (Some people mistake this distortion for their thumping bass)
You do need to bed them in a little. I've only used them for about 10 hrs and can already hear the improvement. To be fair the medium flanged plugs fitted my ears perfectly and isolated the sound pretty well(Other people aren't so lucky). They do disappear into my ears about 2cm into my ears but for me they are pretty comforable!
I had a pair of the Shure SE210's (No Mic) and I thought these were pretty good, they are definitely not as good as the Etymotics
Haven't tested the mic much but appears to work pretty well so far.
There is just one button on these. One click for pause/play, two for next track, three for previous track. Works pretty well in my opinion
Would highly recommend!!
