Sure thing, but I'm enjoying these so much I won't be burning them in.
Great to hear on the 400. If you could PM me or post on here what method you used to remove the glue holding the S500 drivers into the plastic grill I would appreciate it. I am thinking if the S400 works out the way I want it to, I will start playing around with modding my S500 again and prolly put the drivers in a closed full size. I already tried an open set and Im firmly leaning toward keeping these closed as they were designed.
I used the smallest/thinnest slot screwdriver I could find and stabbed my way around the driver. That and also a lot of glue scrapping using the same screwdriver.
Just need to be patient and take your time with it. Once you've gotten around 1/3rd to half of the driver free from the glue you should be able to pry it out with the tips of your fingers.
Don't be like me, I ended up banging up the driver plate(consider it pseudo destroyed) and slipping a few times with the screwdriver, stabbed deep on the tip of one of my finger.
Right between the flesh and finger nail.
