Review / Info: (8/10) The DR-A70C model I obtained has noticeably thicker and sturdier construction, particularly in the metal headband that sits over the head. It also has additional wiring to accommodate its bilateral microphone system. Unfortunately, I have not been able to test the microphone functionality, as I do not currently have a microphone input that uses the 3.5 mm plug system. These earphones use two separate plugs: one for audio and one for the microphone. From my initial listening, I was very pleased by the familiar tuning characteristic of other models in the MDR-A/W series, particularly its deep and boomy bass. However, with closer listening, I found that the DR-A70C has a noticeably flatter presentation than most other models in the series, even more so than the MDR-A50LV, although it does not reach the level of neutrality or harshness found in the MDR-W30. The DR-A70C reproduces vocals and treble-focused instruments particularly well without sacrificing its tangible bass presence. There were, however, moments where I found the upper frequencies to be somewhat harsh. In terms of detail, this model, like many of the higher models in the series, provides excellent texture and clarity in instruments, comparable in some respects to the MDR-W50. Despite its more neutral presentation compared with the MDR-A50LV, the DR-A70C still provides less separation between individual sounds and instruments, again resembling the presentation of the MDR-W50. Nevertheless, the DR-A70C is an excellent and surprisingly capable entry in the series, particularly considering its unique microphone system and sturdier construction. Of note, these earphones were commonly sold together with the WM-R15 (recording Walkman).
