Harman Kardon upgrade

[Onahi]

Has anyone upgraded their Sena 50S HD speakers for the new Harman Kardon speakers ?
Did it make any noticeable difference ?

I did the ones in my 30s

huge difference , the 30s also has a sound profile for using the upgraded speakers

Well worth it

My 50S has the HD speakers. I don't want to buy the HK speakers if there's not really much difference.
