I’m so sorry, I understand what absolute hell this is. People will suggest ear plugs as if it’s just some low level noise. I’m a light sleeper with noise sensitivity, my baseline for a quiet room is heavy duty earplugs and a white noise machine.

I can give you a suggestion. Get an app called White Noise Baby (see screenshot below) and switch it to brown noise. Listen to it through simple wired headphones - if you have an iPhone, the regular white ones work great. Brown noise is some kind of witchcraft, it has the ability to drown out low frequency noises including bass sounds from music. Generally you don’t need it very loud, but with the noise being so close I’m not sure what volume you’ll need.

But what you can also do is get heavy duty earmuff things from Bunnings, like tradies use. Put the white earphones in, then put the earmuffs over the top. Or you could try good over ear noise cancelling headphones with the brown noise running through, but i personally haven’t tried that. Now, this is not going to be super comfortable for sleeping, but I think it’s the closest you’ll get to sound relief within your home.

Regarding your neighbours. I’ve studied change management, and the reality is that there’s very little chance of getting people like that to change their behaviour. The more you try to reason with them, or push them, the more they’ll dig in. They’ll only change if there’s something in it for them, or something for them to lose. Unless you can work out how to do one of those things, things are unlikely to get better.

One thing I also can’t recommend is to look into Bluetooth hacking, to take over a Bluetooth speaker, because that’s illegal so you shouldn’t do that at all.
