Kind of off topic, but I have to laugh at the sheer amount of bass difference tip swapping can create with my Rose Pudding. I wanted to try out a bi-flange tip I had with a larger aperture than I was using, assuming bass might increase. Not paying that much attention, I swapped the tips and tried it out, going back and forth a couple times, and the tips I had previously been using, a smaller sized bi-flange had noticeably and without doubt more bass than the larger aperture bi-flange. So actually paying attention as I swapped tips back and forth just to see what other differences there might be, I noticed that the larger tip slides all the way down the nozzle, leaving the mesh nearly at the end of the tip, where the smaller tip (which this particular tip is easily my favorite tip I've ever tried) only allows the nozzle to go halfway or so through the tip, leaving more space. I might have to look into spacers before I try the larger tip again.
And now for something completely different: Does anyone have any thoughts on the KZ GR as it's only $6 with free shipping, and allows for tuner swapping like the ED9? http://www.aliexpress.com/store/product/KZ-GR-Metal-Retro-Copper-Gold-Headphones-Stereo-Noise-Isolating-HiFi-Bass-In-Ear-Earphones/1358152_32612691117.html?spm=a2g01.8041047.101.1.xD1d5Z&sdom=101.282758.225819.0_32612691117
