1. ASG-1 is the universal fit earphones
2. ASG-2 is not out yet and shouldn't really be talked about. Dale, the director at Aurisonics stated that the ASG-2's might come out in summer or even later after its been tested by their musicians and used (liked) by them.
For previous ASG-1 owners it will be an upgrade option available. The ASG-2's will have a dual driver, one being 15mm the other 10mm in the same sheel (unconfirmed, but assumed, seeing as ASG-1 owners can upgrade)
3. AS-2 will be the "upgrade" to the AS-1.
The AS-1 is like the ASG-1 but instead of being UNIVERSAL its based on CUSTOM ears
4. AS-1b is just like the AS-1 but has an adjustable bass port
So in short:
AS-x = Custom-made earphones
ASG-x = UNIVERSAL earphones
1's of the models have been released
2's of the models have not been released and won't be available till Q3 of this year.

Anyone have thoughts on the ASG-1 sound quality at low listening volumes?
