Shark would be correct.
Currently, there are two versions of the UE 700 in the market: one fits a 200-size Comply Foam Tip, the other is not compatible with anything. We had to remove it from our site and label it Not Compatible because customers from both of our companies were confused. I believe Ultimate Ears is working on reverting to the old sound port design, or is adjusting it again to fit our tips. Don't quote me on that though, I'm not really in the loop for those discussions.
Unless you know exactly what to look for in the sound port design, it's impossible to tell the two earphones apart — they are identical in every way except for the sound port. If the sound port of your earphones is shorter (average looking) with an angle ridge slanting downward toward the earphone body, then it IS compatible with our tips (T-200, Ts-200, Tx-200). If the sound port looks a bit too long and has a flat ridge that acts as a stopper, then it is NOT compatible.
Sorry to see that this looks to be the version that is not compatible with our tips.
Best Regards,
