I got the pro alpha. The high are way too bright, headache inducing actually. I use them to listen to Spotify on my Nexus 5x. The interesting thing is that these earbuds are the only ones that respond well to Spotify's built in EQ and it actually improves the overall sound. The proalpha's tanglefree cable is pretty awesome. Overall great for the price I paid.
foureight84"headache inducing"! Same here. But with my iPhone's "treble reducer" EQ they sound very nice. And the double flange tips actually work in my small ear canals. So over all, I'm pleased with them for the price.
