VINABTY Sony RMF-TX300U Replacement Remote with Voice

VINABTY RMF-TX300U is a direct replacement remote with built-in voice control designed to work with a wide range of Sony Smart 4K TVs.

If your original Sony remote is lost, damaged, or no longer responding, this VINABTY replacement replicates the RMF-TX300U/RMF-TX200U/RMF-TX201U layout and functions to restore full control of compatible Sony XBR, KDL, and KD series televisions. It pairs instantly with supported models and reproduces the same button arrangement and voice-search capability, so you can navigate menus, launch streaming apps, and control volume and inputs as before.

Which Sony TV models will this remote work with?

This replacement is engineered to be compatible with many Sony 4K and smart TV families. It supports a long list of XBR, KDL, KD and A‑series models from various years; check your TV’s model number against the compatibility list before purchasing.

• Compatible with XBR series such as XBR-55X850S, XBR-65X930D, XBR-75X940D and more.
• Works with KDL and KD lines including KDL-50W800C and KD-55A1 models.
• Supports earlier RMF-TX200U/RMF-TX201U replacements where TV firmware accepts the remote.

How does voice control work with this replacement remote?

The remote includes a voice button that triggers the TV’s built-in voice assistant (when the TV supports voice input). Press and hold the voice button, speak your command, and release to let the TV interpret searches, open apps, or change settings.

• Activates your TV’s native voice search — no extra apps required.
• Works for searching content, controlling playback, and selecting apps on supported Sony TVs.
• Operates like the original Sony RMF-TX300U voice function when paired correctly.

What functions and buttons are replicated on this VINABTY remote?

The layout mirrors the original Sony remote, including navigation controls, dedicated app buttons, numerical pad, playback controls, and the voice key. That means you’ll regain direct access to input switching, home/menu navigation, and commonly used streaming shortcuts.

• Full directional pad with OK/Enter center button for menu navigation.
• Playback controls (play/pause/rewind/fast-forward) for streaming media.
• Dedicated buttons for Home, Back, Options and input selection.

Is setup difficult and what should I expect after installing batteries?

Setup is straightforward: insert the appropriate batteries, point the remote at your TV, and it should connect automatically if your TV model is supported. If the TV does not respond, verify model compatibility and battery orientation, then try the remote from close range.

• Requires standard batteries (not included) — install according to polarity markings.
• Auto-pairing with compatible Sony TVs; no programming needed for most models.
• Test voice and navigation functions immediately to confirm full operation.

Who is this for: This VINABTY RMF-TX300U replacement remote is ideal for Sony TV owners whose original RMF-TX300U, RMF-TX200U, or RMF-TX201U remotes are missing or malfunctioning, and for anyone who wants the same button layout and voice control functionality without buying an OEM remote. It’s especially useful for households using Sony XBR/KDL/KD 4K smart TVs that accept third‑party replacements and want a cost-effective, fully featured control option.
