I recently refurbished a Bose IE, so I don't know what it's supposed to sound like. Music definitely comes out, and it's all there, however, they sound anywhere near as good as I expected. I was surprised, since I like the Bose Triports, and some "audiophiles" here who have bashed the Triports, have praised the IEs, so they must be better, right? (I dislike the Bose IE and QuietComfort).
Compared to my $25 Chinese-made ViSang R02s, they sound bad. The upper midrange is the loudest, bass is moderate, and treble is barely there past 6kHz. There's a dip around 2-3kHz, and the bass has very little impact. Overall, they sound a bit dark and distant, and muddy in the upper bass and upper midrange around 5kHz.
Originally the right and left channels were shorted and the ground was disconnected.
I've replaced and measured the wiring, and I can't find any problems with it now.
Can any one else confirm they sound like this?
