Hi ericp10, as I indicated in my PM to you, the diameter of the Audeo silicone tips is about 1/3 the size of the 900's nozzle, so getting them on was a b***h!!! The sibilance is gone, for the most part, but I feel that some of the great highs are also gone and the phone sounds a little muffled now.
Sorry for the amauterish pics but you can see how the Audeo tip tube is also almost twice as long as the 900's nozzle and so the tip narrows back down toward the output. You can also see the difference between openings using the Shure olive foam tips compared to the Audeo tips (large size).
What kind of detrimental effect would you expect from having a
narrower output tube and also
further away from the tip of the phone nozzle? I thought I would get greatly reduced bass but it all seems to be there but
only with the Audeo tips over the ears as this is the only way I can get a decent seal with the smaller Audeo tips.
What do you think about cutting the Audeo tip so it is the same length as the 900's nozzle to place the driver closer to the eardrum? Would this bring back some of the sibilance that is now gone?
Any feedback is most welcomed!!
TIA.
