Problem is not how weak or strong the encryption is
Here it's definitely part of discussion. The context was
It’s encrypted anonymous communication capabilities.
It's barely anonymous, and poorly encrypted. The latter is the reason Durov is in custody while Signal devs are scott free. He could easily turn illegal stuff over to French authorities, but doesn't.
The bigger problem is that people somehow assume this a huge threat, while all previous cases didn’t involve anything like that.
There have absolutely been cases where a backdoor/weakness/lack of encryption used to catch criminals before: https://en.wikipedia.org/wiki/Operation_Trojan_Shield https://en.wikipedia.org/wiki/Ennetcom https://en.wikipedia.org/wiki/EncroChat . I distinctly remember that there were also arrests of opposition activists in Russia based on personal messages in VKontakte, but can't find the news right now.
real criminals do their stuff everywhere (especially on telegram) for years, staying safe.
Some are staying safe, others are being caught precisely because of this.
Problem is not how weak or strong the encryption is, but that once you are under oppression and do opposition activities, you’re going to learn by yourself how to deal with it.
Using better encryption schemes is definitely part of that.
I'm not sure you should "cheap out" on headphones per se. The really cheap ones are usually horrible, both in terms of sound quality, usability and comfort (well, except for wired Apple ones, allegedly, though they never fit me right). It's just that it makes no sense to go for really expensive ones, unless you're really into audio and love hearing the tiny sound reproduction differences between them, or enjoying the different tech etc. The middle ground of $50-$100 for in-ears and $100-300 for over-ears will often offer you good/great/excellent sound quality and the same usability&comfort as more expensive ones.
