I haven't done a thread on it , but I got it from this video. https://www.youtube.com/watch?v=9QpgDCYyRcY I did it. Bought a set of the Panasonic headphones on Amazon. Cost me $20. The headphones are normally $60, but most ofteb if you pick the right color, you canfind them for much cheaper. Color doesn't matter because it's only the speakers you're using. Don't know how they compare to the speakers with the 50S, but they sound great and so much better than the stock.
You know I would love to come out west. Been wanting to get back to Colorado since I was there 2 year ago. The dates would be hard for me I think.
