Im curious: can you give me example of how you would use a vacuum tube port on your iphone? Here is my story: i left my cruise cabin in the middle of the night and went to the bow. In shock I discovered it was almost as bright as a daylight - oh my the full moon looks beautiful. I was alone and played the titanic scene for a monent. Imagine me alone, warm summer night, carribeans, full moon and cruise ship gliding through quiet ocean. Perfect moment hard to repeat with all these circumstances. I immediately reach out to my pocket to put headsets on just to listen to some Leonard Cohen’s songs. Imagine my shock when I realized I forgot the iphone’s jack adapter ;(
