After the very popular W Pro (a.k.a. TWF11R), Radius decided to keep the heat on and announced the W Pro II. There isn't much spec at this point, but the DDM (dual diaphragm matrix) system is expected to be in the new IEM as well. The releases date is around December and we will know more about by then.
After the EX700 almost 2 years ago, Sony has been quite quiet in the IEM market - Not anymore. Here comes the MDR-EX1000, the new flagship that aim to put all its competitors to shock. Large 16mm driver, liquid crystal polymer diaphragm, magnesium housing, user tunable sound, removable cable and a gorgeous leather box are just for starter. The MSRP in Japan is estimated to be over US$700, most definitely not your budget option by a long shot. It should be released soon so it is time to break the piggy bank, that is if you have that big of a piggy bank in the first place. Do check out some closeup shots in its Japanese photo gallery, but Flash required.
