Westone is introducing a new series called the UM Pro with three new models, UM Pro 10, 20 and 30. So far they look very much like the old UM series with similar driver configuration, same price tag, shinier packaging and an user replaceable cable with the very *dreadful* MMCX connector (same as the one on Shure). Just by the connector itself, Westone seems to be taking a step backward...oh well, not sure what is so "pro" about them.
