I have for sale my Sony EX800ST in-ear monitors. These are in mint condition and will include the original packaging, manual (in Japanese), case and 4 sets of Sony hybrid eartips. These phones have the same type removable cables as the EX-600, 7550 and 1000 and do have a very similar SQ to Sony's flagship EX1000. The EX800ST has a SQ that is very well-balanced across the audio band. Bass is deep and well-controlled while highs are smooth and exhibit no sibilance. An excellent all-around performer. While easily driven directly from a source player, these phones scale very well with quality amplifiers.
