I bought the David Lucas Burge Perfect Pitch Ear Training course many years ago. It was a 12 or something CD package where he talks through the process of listening more and more deeply to notes with the ultimate goal of hearing the difference between a B and an F#.

I ultimately didn't make it. Sometimes I would think I heard the difference, others not. Not sure there is huge value to having perfect pitch, although it appears to exist as a real thing. Relative pitch skills, on the other hand, are very practical.
