Sony RMF-TX621U Voice Remote vs Sony Bravia Voice Remote Replacement
Buy the Sony RMF-TX621U if you own a recent Sony Bravia or XR set and want the remote Sony designed for it: metal front, backlit keys, voice, and RF pairing that works without pointing. The generic voice remote is a cheaper-feeling third-party replacement with a two-year warranty and six streaming buttons, but it is infrared only, so you must aim it at the TV. Owners of the Sony remote report it works perfectly and arrives as described; the generic one has little owner feedback to judge by.
- Choose the Sony RMF-TX621U if you have a compatible Sony Bravia or XR TV and want backlit keys, a metal front, and RF control that does not need line of sight.
- Choose the generic Sony-compatible voice remote if you want a spare or replacement with a two-year warranty and six streaming shortcuts and do not mind aiming it at the TV.
