Here is a new entry to TDK more budget / casual oriented CLEF series of IEM called the CLEF-BA (or BA700, if you like). It is single BA based, 55 ohm impedance with a silver plated OFC cable (if I am not mistaken). Being the budget line, the IEM will be sold at just under US$80 in Japan sometime this summer (staring mid June). Anyway, the slightly interesting part will be its adjustable outer ear rubber 'hook' (*not sure what to call it, the blue part in the picture above) that will provide the user with a more secure fit. This design is kind of like the long discontinued HifiMan RE252, but with more flexibility.
