I am gonna predict these will be in fact ISNs version of the Penon volts tuning. There are more similarities to the Volts Fr vs the H40. If so these are gonna take off like hot cakes.

It will be interesting to know what DD they are using for the bass. Sonion BA for the mids with that FR graph is already a guaranteed win IMO.

EST50 is almost in blind buy territory.

Well I can assure you guys the Dynamic being used will be high quality. I have a feeling it might be the very same dynamic used for the Globes, Orbs, Volts.

10mm dynamic driver, graphite fiber silk paper dome soft, grainless overhanging diaphragm, long-stroke, high-sensitivity surging bass.

They arent gonna throw in premium BAs and EST and then throw in a generic plastic dynamic.

Love the material choice for the DD. I think they are aiming to have the speedy bass to match the BAs and ESTs for an ultimate coherency. Nice!

Hello everyone,
Just provide some information.
The mid-frequency BA and bass dynamic driver used by ISN EST and Penon are different. If use the same driver with different tunings, I think it is meaningless. Thanks for your attention.

Hello everyone,
ISN EST50 initially made 5 different faceplate samples, and finally chose 2 colors, blue and green .
