Purchased the FS-HAL1s to replace my recently evaporated (ie gone AWOL, soon to reappear now that I purchased a new pair) NuForce pair that were a few years old. I love the sound of the FS-HAL1s and have uber subjectively tested them from punk to Chopin. I am very happy with my choice. Build quality seems great and they fit my ears well. I did use one of my own silicon ear tips for my left ear since it is inexplicably different than my right. The right one that came with the earbuds fit great.
