The US military heard it and didn’t necessarily want to give away capability of listening devices around the sea floor.
The sub was difficult to get to the debris field because it was at an incredibly deep section that few craft are capable of reaching safely.

It was frustrating they made a big deal about something we ultimately could have done nothing about in the first place. However it’s not like the whole “hearing the implosion” thing was something the military wanted to give away and at that depth we have to be careful. Don’t forget we’ve put more people into space than have been to the deepest point on the planet.

Don’t forget we’ve put more people into space than have been to the deepest point on the planet.

Fun fact, space is easier. It takes more effort to get there, sure. Coming from the "normal pressure" here on earth (about 1 atm) and going to space (0 atm) is a pressure difference of 1 atm. But: Diving into the ocean, the pressure increases the deeper you go. For every ~10 meters (~33ft) you go deeper, the pressure increases by 1 atm.

That means, that a space ships would only need to dive 10 m deep to get to the pressure difference it experiences in space. They went to see the Titanic which is about 3,800 m deep. So the sub needs to withhold a pressure difference that's about 380 times higher than a space ship experiences.

(OK, little difference I omitted: In space you need to prevent the vehicle from exploding, while in the deep sea you need to prevent it from imploding)
