Ts-500 fit, but you have to push them onto the upper part of the nozzle. I've read T130 and T140, but cannot confirm. I also sent Comply a note, but haven't heard back from them yet.
100% without a doubt, you are a .
I crave extension for the weight but not amount for the rumble I am guessing I will think the MKII's are very close to perfect but not quite there as far as bass (I will probably still settle with them as the best IEM choice for me) and the BE's are a little too much.
BE's have quantity/rumble, MKII's are nearly as deep. I think you might be surprised with the MK2's low end weight.
