Was looking for a replacement for my Shure SE846 tips. These did fit nicely and securely in the ear, sizing is good, sounds quality is not compromised. However due to more porous material than the stock SE846 ones they let more mids from outside world in.
Perfect size, work realy well... until the memory foam starts to disintegrate and fall apart after 3 stints of usage. Quite sad about this as the extra length is great. Far too expensive for the short period of use though
By far the best noise cancelling ear tips I've used!
