It’s the best GE-90 sound in the world.

In the late 1990s, Boeing began developing ultra-long-range variants of the 777, the 777-200LR and 777-300ER. For these aircraft a more powerful engine in the thrust class of 100,000 lbf (440 kN) was required, leading to talks between Boeing and engine manufacturers. General Electric offered to develop the GE90-115B engine
The GE90 engine was launched in 1990 to provide a large turbofan engine for the Boeing 777, a wide-body, long-range, twin-engine jet airliner.
