This is a response from cosmic ears regarding the sound signature.
Thank you for your kind comments.
In summary I would class the following sound signatures:
Pure with dynamic driver: Bassy (lows boosted, mids and treble recessed)
HY3 or Flex with Triple Hybrid: Balanced (treble and bass boosted, mids recessed)
We have a priority task to add the sound signatures on the website for all our models as this seems to be a common request.
The limited edition red is not currently available, we are however going to introduce a similar limited edition red model this month, we may get a post up this week to show the red model as we will also have a similar limited edition blue model. I will try and remember to let you know when we put the post up.
I hope this answers your questions.
I would like to have a flat sound signature. Maybe have blue as stock color, rather than purple.
Comparison to similarly-priced universals would be highly appreciated.
