I lost/ruined my OEM tips for my ES SM3v2's so I ordered some of these from the UK. I was about to only order 1 pack for myself, but then I figured someone else in the US might want a pack and want to save a little bit of money (the shipping from the UK for these is killer!)
So I ordered 3 packs total, leaving 2 packs for sell.
I also ordered a pack of 10 shure yellow foam tips off Amazon, as I will need to cut out the cores to put on my SM3's to fit these Sensorcom tips.
Btw, the $20 is for 1 pack. Saves you about $10 ordering from the UK.
EDIT: So for some reason the tips fit on my SM3v2's without any modifcation. Unfortunately, these tips don't seem to completely fill my ear and leave a lot of outside noise leaking in (really useless for when I'm riding my motorcycle). Gonna just stick with the shure foam tips I guess.
