RMF-TX520U Replacement Remote for Sony TV - Voice Control

In this review of the RMF-TX520U replacement remote, the bottom line is simple: this is a practical, budget-friendly spare or replacement for owners of Sony Smart TVs from 2019 to 2023 who need full voice-command support and quick access to streaming apps. The remote reproduces the original RMF-TX520U layout, responds to the TV in roughly 0.2 seconds, and works up to about 15 meters, making it a convenient second remote or a like-for-like swap when the original is lost or damaged.

Key Features

• Voice control support: Built to work with Sony TVs that support voice commands from 2019 to 2023, so users can search, play music, or ask the weather hands-free.
• Streaming hotkeys: Dedicated Netflix, Disney+, Prime Video and YouTube buttons speed access to popular apps without navigating menus.
• Quick pairing: Pairing is straightforward: long press VOL(-) and the Google Assistant button for two seconds and the remote enters pairing mode with the TV.
• Fast response: The remote claims a 0.2 second response time and works up to 15 m, which keeps navigation feeling responsive across a typical living room.
• Full-function replacement: All functions mimic the original RMF-TX520U, making it a plug-in replacement for compatible Sony BRAVIA XBR/XR/KD series models.

Who It's For

The RMF-TX520U replacement remote is best for Sony owners with 2019-2023 models who need the same voice and app functionality as the factory remote. It is especially useful as a second remote for family rooms or as a direct replacement when the original is missing.

It is not suitable for older Sony TVs made before 2018, and it will not control external TV boxes. Shoppers who require universal control for multiple devices or support for pre-2019 Sony models should look at other universal remotes or model-specific alternatives.
