how often does it happen that you find a product which covers any demands you had about a problem?

for me, that was the case when i discovered open-ear buds.

i don't like regular in-ears and proper headphones are impractical when moving aroud. also. i like to have some awareness of my surroundings and want good quality hands-free phone calls.

these things solve all of those requirements. i sometimes even forget i'm wearing them at all. sound and mic quality are great.
