All right, so it is about time I put my opinions down. I have been having trouble uploading photos I took of these and will continue to try to load some.
My listening included sourced from and iPOD Touch 3G, BB Q10 playing Pandora, and my MacBook: ALAC > iTunes > DragonFly 1.2v > CustomArt. Music primarily ranged from Lindsey Stirling, Apocalyptica, Shelby Lynne, Eminem, Green Day. I also listen to other artists, but less time was spent with them.
Initial feel. These all had a slight tacky feel due to the silicone, they are very comfortable and I never felt like they would slide out of my ears. Even the cables felt soft to the touch. All had standard 90 connectors to 3.5 plugs. The One is a black cable and opaque. The Two and 330 are a soft white rubber and allow sight of the cables inside. The 330 has the clearest silicone allowing a nice view of the electronics floating inside the iem. The cable length is about 44" from the connector to the Y, and 10" from the Y to each ism, There is no attachment point. It is a solid connector into the silicone iem, which I was worried about initially. I tried both wrapping over the ear and drop down for the cables, I found the drop most comfortable. The cables run out the front when set in my ear and I had no discomfort wearing them, my listening times ranged from 30 minutes to about 4 hours.
Music One. This has a nice sound, well balanced. I heard low sounds as a punch, not booming. Not a bass heavy setup for rock music, but showed what the music can do. This was comfortable to listen to across my library. All the music sounded good. Nothing dominant, just allowed me to relax and listen.
Music Two. Slightly more clear than the One, but more high forward. I felt I heard less bass on this one that the others. It played the whole range of music without any problems, I never felt it was maxed out on range, went high into the treble and low into the bass, just less focused on bass. As Barra stated, "a good impact/" I heard the bass, but it was not dominating the music. There, then gone.
Pro330v2. Overall, better than the others. I feel clarity is a great description and well balanced. It allows full range and I never felt it struggled to show all the range. I felt on my phone and computer, there was some slight background air when I wasn't playing music. This was very quiet and never was noticed when the music started. This one just sounded better than the others, more clear, more punch on the bass, and more treble. I never heard breathing, but I did hear audience conversation listening to a live album.
Overall, I want to thank Peter for allowing this tour, and Barra for organizing it. I enjoyed my time listening and really like the feel of silicone as a form. It is nice to hear single and dual drivers produce quality music as companies seem to race to create more numerous driver oems.
