For those with a deeper wallet (it's not expensive for what it is though) and/or 2 left hands: you might want to try the Mr Speakers Alpha Pads ;)
I tried these with the Hifiman 4s and 5LEs with excellent result! The comfort is the best of any Hifiman pads I tried (this include the old velour pads) and the sound is shifted (slightly) toward darkness (the whole is not dark, of course) for the most natural result I heard.
This is good to know. I'm on the fence about using the J$ pads at the moment for the HE-5LEs. While it would only take about 10 minutes to get them up and running, I also don't want to contort the headband in such ways yet so they'll handle the slightly thicker J$ Beyerdynamic pads.
