KOOMOER For Sony TV RMF-TX800U
The KOOMOER remote replaces the RMF-TX800U and works with all 2018-2025 Sony Bravia Google TVs, including 4K UHD and OLED models, with voice control via a dedicated mic button. It adds four quick link buttons for Netflix, YouTube, Disney+, and Prime Video, and pairs through the TV's Bluetooth settings in seconds. Best for Sony TV owners who want a budget-friendly replacement with voice search and one-touch app access, though it lacks portability features.

Snapshot
The 30-Second Version
The KOOMOER RMF-TX800U is a dirt cheap replacement remote for a huge range of Sony Bravia TVs. It's not fancy and the build is light, but it gets the job done for around $16. If you need a working remote without paying Sony prices, this is the one.
Pros & Cons
Pros
- Works with a massive range of Sony Bravia TVs from 2018 to 2025 68th
- Voice control button included for compatible models 66th
- Quick link buttons for Netflix, YouTube, Disney+, and Prime Video
- Dirt cheap compared to an official Sony replacement
Cons
- Batteries not included, so you'll need to grab some AAAs
- Build quality feels flimsy and lightweight
- Voice pairing can be finicky on some TV models
- No backlight, so good luck in a dark room
The proof
Performance
Setup is straightforward if you follow the pairing steps, hold VOL- and the Mic button for a few seconds and you're in business. The voice control works on compatible sets, and the quick link buttons do their job. But this is a budget replacement, so don't expect premium build quality. The buttons feel a bit hollow and the plastic is light. It's functional, not fancy. In our database, it lands around the middle of the pack for display and social proof, but it's not winning any awards for smart features or connectivity.

vs Competition
Compared to the LOUTOC TX810U, another popular Sony replacement, the KOOMOER is basically the same idea at a similar price. The LOUTOC might have slightly better button feel, but the KOOMOER has more model coverage. The TAGUO Apple TV remote is a different beast entirely, no Siri and no touch, so if you're in the Apple ecosystem, skip this. The Mounting Dream MD2263-XLK is a TV mount, not a remote, so that's not even a fair fight. For Sony owners, the KOOMOER is a solid pick among the budget replacements.

Value & Pricing
At around $16 USD, this is a no-brainer if you just need a working remote. An official Sony remote can run you three or four times that. The KOOMOER won't feel as nice in your hand, but it'll change the channel and turn the volume up, which is the whole point. For the price, it's hard to complain too much.

Common Questions
Q: Will this work with my specific Sony TV model?
It's designed for 2018-2025 Sony Bravia Google TVs, including XBR, XR, KD, and KDL series. Check the compatibility list in the description to be sure, but coverage is broad.
Q: Do I need to pair it for basic functions?
Basic buttons like volume and power should work right away, but voice control requires Bluetooth pairing. Hold VOL- and the Mic button for 3-5 seconds, then connect through your TV's settings.
Q: Does it come with batteries?
No, batteries are not included. You'll need to supply your own AAAs before you can use it.
Who Should Skip This
Skip this if you want a premium feel or a backlit remote for dark room viewing. Also skip it if you need Siri or Apple TV control, this is strictly for Sony Bravia sets. If your original remote still works but you just want an upgrade, this isn't an upgrade, it's a sidegrade at best.
Verdict
If your Sony remote is dead and you don't want to spend official money, buy this. It's cheap, it works, and it covers a ton of models. Just don't expect it to feel like the original. It's a utility purchase, not a luxury one.
