Thanks musicday, first thing that came into my mad mind.
Regarding your last question, here is an image with the Westone/Shure grey silicone which I squeezed on.
No you will not get an "olive" on though due to the rigid core. If you do want to use foam, the T400 series fit but unsure what the true series number would be, maybe T500?
Never heard the IE800.
At this price range there isn`t really better for a normal universal, most can deliver good audio and is really signature/genre related differences.
I listened to Radiohead via my W4 on the way to work this morning and due to the nature of the W4, great mids and pretty intimate soundstage work really well with them whereas the SD3 is too much of "phone", not delicate enough.
This could be the mp3 quality of the album I have. Although it is 320kbps I don`t think this is good enough for the SD3 imo. I mentioned the Little Dragon - Ritual Union album in the review which sounds fantastic on the W4, better than most that I have on my Ipod touch.
With the SD3, it delivers the album with more of a warm feel but due to the added space it is a much better sound experience than with the W4.
I hope that makes some sense. I will say again these are like a home cinema in comparison to the W4 and you may not like how the sound is delivered but there has to be a compromise to allow you to have a big space filling sound?
Pretty much why I think in a nightclub, you are not after pure audio, you want big full thumping heaven that just sounds good. If you would rather go to a classical concert then that is your choice, I may even join you on a night off
Edit: Once you get used to the signature and delivery these can be subtle with great impact. One surprise after another.
