In my case, the largest size of the Wh2 fits me well and the sound is very good, but after a few minutes my ear begins to sweat a little and they begin to slip and the sound quality is totally lost and as they pass the minutes hurt me a little in the lower part of my ear.
I bought the Spinfit CP360 because I have always used size M in eartips and I figured that if I was using the bigger ones with the Hiby ones, the bigger ones of the CP360 would fit me better.
The XL size of the Spinfits don't fit me and they don't fit in the case either, the L size does fit me but I still feel that they are somewhat large, in the case at first it seems that they don't fit, but if I close the case they do load, The bad thing is that with the Spinfit CP360 the bass is reduced a bit and the treble is lost a lot, I suppose it is because since they are a bit long there is more distance between the driver and my ear. I would like to know which one of you fits the larger size of the WH2 better and which one did you replace it with? I don't know whether to buy the Spinfit CP360 M or the CP1025 M.
