For a smaller diameter, try these.

These seemed a bit larger in person but look lovely in my ears. I did have to spread one of them to get it into my ear, the pair was not opened the same at the bottom. They have nice weight and a bit of swing to them and they do turn a bit so I reach up and make sure they are hanging straight from time to time. I bit too large to sleep in but that was not my intention anyway.

The insertion gap on these is tiny so I'll probably have to open them up a little bit but other than that they seem to be pretty good.

I love the weight.
Great quality and medium size.

Just make sure if you want a pair you order both at the same time. I had one from a previus order (I got it for my septum) and the curve and diameter on the ends aren't quite the same.

4g
I've bought every size omega from 10g up to 4g and they just get more awesome with each size increase. The 4g are solid and weighty looking but not too heavy.
