I have recently switched from vented sleeves on my KS8 HA’s to closed sleeves. One of the big differences I have noticed is that when I stream iTunes music from my iPhone the sound is terrible. It has no bass and the mid to highs are shrill. With the vented sleeves the sound was good, not excellent, but for sure way way better than what I am now getting.
Does anyone have any experience with this and what adjustments may be necessary? One of the things I noticed is that when you go into the Fine Tuning and Audio Streaming / Bluetooth tab in Connexx 8 there is totally different equalization applied by default for closed vs open fittings. I presume that is because the closed should be trapping the bass and less bass equalization is needed. But what I am hearing is not enough. I was thinking about asking to go midway between the two equalizations to see how that sounds. Thoughts on this?
Here is what the equalization looks like for the open sleeves. Each bar is one dB.
And here is what the closed sleeve equalization looks like:
