BLUR UPDATE # 2; 15 AUG 2021
It was getting a little 'hectic & hairy' for me correctly maintaining the "
currently available earbuds list" I was posting so I decided (with the blessing of Wong) that it would be much easier to simply highlight, in
bold Hulk green, those models currently available for order on the
Blur Models Timeline as follows (this should be much easier for me to keep updated):

So currently, there are three (3) available models you can order:
1.) Blur 266v2 MX aPs Retune (available in five different impedances)
32Ω - New Retuned FR Curve can be viewed here on the FR graph
here
64Ω - New Retuned FR Curve mimics that used on the Blur OFC MX64 aPs Special Tuning Edition
150Ω - New Retuned FR Curve increases the bass, mid bass as seen on the FR graph
here
300Ω - New Retuned FR Curve is an improvement on the Blur MX300 美魔女 Beautiful Witch aPs. This better tuning increases the mid bass which has pushed back and lowered the second mountain resulting in a much less aggressive down & up frequency line (more smooth) cutting another naughty mid spike. This is the similar tuning used on the Blur MX300 美魔女 Beautiful Witch aPs Special Edition in the Stingray silver metal shell.
400Ω - New Retuned FR Curve is currently being fined tuned; receiving a nice boost in the sub and mid bass frequencies; will be ready for order.
2.) Blur 266 PK32 (
Blur 256/266 PK16 White Face replacement with "New Line" tuning; see my
update post just above)
3.) Blur OFC MX64 aPs Special Tuning Edition (see
here)

Never fear though! Wong is working hard on a number of projects some of which will be released very soon... here are a couple to tease you all:
- Blur MX300 美魔女 Beautiful Witch aPs Retune (Not Available Yet) - A similar FR curve to the Blur 266v2 MX300 aPs Retune (see above) with different cabling. Wong's mission with this retune is to further improve vocals which has always been the primary focus for the Beautiful Witch since inception.
- PK?Ω Minimalist Earbud Secret Project (Not Available Yet) - A very Limited Edition model (unfortunately, only one-of-one) is forthcoming which will kick off a new minimalist model line that will use the same driver & tuning, similar cabling, but different termination style/type.
