Tried them on/in briefly this morning with the set of connectors on and they fit really well, still gonna try out the others later though when I have time.
The main reason the Sony's failed was build quality , not something I expect to see with the Shure as they are much more heavy duty !
UPDATE: 12th April - two things I now know for sure having used them a lot recently:
- they are excellent 'phones'
- I have NO wax left in my ears
