Our Verdict
Sony X80J
Sony X80K/X80CK
The Sony X80K/X80CK is the replacement for the Sony X80J, and both TVs are nearly identical, with only a few differences between them. The X80J is a bit better in a few areas like its improved color accuracy and faster response time, but the X80K also has less stutter. The X80K comes with the updated version of the Sony remote, but it has the same voice control features as the remote with the X80J anyway.
