Hi there
The two remotes in question:
The RMF-TX100E is designed for Android TVs which includes an inbuilt microphone and button. The RMF-ED004 is build for 2014 Bravia TVs. As I have not tried either remote on each of those TVs, then I can only suggest that you stick to the RMF-ED004 remote control. Unless another forum member has done so and can confirm or deny compatibilty.
Also note the other buttons of 'Discover' and 'Options'
Cheers
