I hope you love them as much as I do, if I recall this would make you only the 4th person to own an MX400 bud. Resolution is absolutely ridiculous.
I was thinking the same, but there was another order of the MX400 when he shipped mine out. I guess this model is in higher demand than we both expected, although not as much as the other models. Probably because of the higher impedance which makes them more for desktop use.
Indeed, the 400Ω is the rarest driver that Wong has used with a total of
only thirteen to sixteen earbuds ever made using this impedance driver since it first debuted in the 2018 Blur 1/3 Copper.
Currently, there have
only been five (5) earbuds made now using the
new version 400Ω driver.
Unfortunately, Wong has had to temporarily suspend this driver option on all models. This recent newer available version of the 400Ω driver has proven to be very challenging for him to install as it is quite sensitive to soldering more so than any other driver he has ever experienced. Unless he can figure out a solution this driver may be discontinued all together. Solved! Wong is currently working on a new, soon-to-be-released model that will utilize these pesky 400Ω drivers... the Blur OFC MX400 Special Tuning Edition (400Ω; non-aPs Clear Shell).
400Ω Newer Version Total = 5
2021 Blur 173 MX400 aPs (2)
2021 Blur 266 MX400 aPs (3)
The
older 400Ω driver version was used in six (6) models from 2018 until 2020 (seven models if you consider the 2019 silver metal shelled variant of the Blur 1/3 Copper as a separate model). Approximately, a
total of eight to eleven earbuds were ordered and made using the old version 400Ω driver.
