If you're unable to find an original replacement cable or other aftermarket cable with the right mmcx connector, it is possible to modify a very inexpensive generic mmcx cable to fit without modifying/damaging the IEM itself. I've had my ie300 well over a year, I use it regularly and its like new. I have some Sony IEMs with a similar type of connector and haven't had a single problem with them, they're over 8 years old.Received mine as well, while I don't have an issue wtih the cable as yet, am also wondering on replacement options down the track if things go wrong.
