The K4 is also known Vibe X3 Lite and for a good reason - you get much of the same quality hardware and advanced features at almost half the price of the Vibe X3.

Lenovo Vibe K4 Note review
Most impressive is the multimedia focus of the Lenovo Vibe K4 Note. It starts with 2x 1.5W stereo speakers around the 5.5" screen, then there's a Wolfson audio codec for high-quality playback. This chip also manages the 3-mic system and cancels acoustic echo and ambient noise in the 1080p videos shot with the phone's 13MP camera.

And Lenovo built its own VR tech called TheaterMax, but first, let's focus on the most important features.
