The sound is great, but I don't see the purpose of this. Boba Fett has no sounds, except the working microphone and speaker (in the Supertrooper footage) and the spurs (in ESB) added later by Ben Burtt.
The Supertrooper footage has some background noise, but this might be the noise from the nearby city (the whole footage was filmed outside) and partially from the telemetry or feedback between Ben's microphone and the Supertrooper's built-in speaker.
In the Empire, the first time we see Boba Fett on the Executor's bridge, there are a lot of background sounds created by the ship's electronics, but there's no 'Boba sound'; the same goes for the Slave I cockpit scene. When Boba Fett appears at the left side of Vader, there's only the sound of the 'invisible' spurs but there's no 'Boba sound'. At the entrance to the Torture Chamber scene there's only a quiet humming noise created by the building's electronics (?), then the spurs again when they are walking to the elevator, but there's no 'Boba sound'. In the Carbon Chamber scene there are clear sounds created by the overall action and we hear again the spurs in the Hallway scene, but there's no 'Boba sound'. In the Slave I's close up scene we can hear the ship's door opening, but there's no 'Boba sound'.
I agree that this is a good addition to your suit, but there's no clear evidence that any of those sounds were directly attributed to the Boba Fett character.
