You've barely heard music if you don't have decent audio gear. If you love it, it's absolutely worth the investment. The amount of music enthusiasts I've met who haven't invested in good headphones or speakers is crazy.
This is something I preach. I honestly nag my music enthusiast friends who haven't bothered investing in decent audio gear, they don't understand what they're missing out on.
It makes the biggest difference. Music literally sounds at least 2-3 times better. It sounds crystal clear. Listening to songs you've already heard is a new experience because you hear so many more sounds you couldn't hear before.
And it's not even expensive. You can get a decent pair of headphones for $150-200 AUD that significantly outperform overpriced trash such as Beats. Sites such as Massdrop frequently have very good deals.
My headphones (the Sony WH-1000XM3, which I highly recommend) set me back about $400 AUD. I use them almost all the time, so I've probably used them for hundreds of hours already even though I've only had them for a few months. It's so worth it.
My speakers (KRK Rokit 5s) and sound card (Focusrite Scarlett 2i2) cost me around $600 on sale. And again, I've spent ages using them so it's worth it. I don't expect to ever have to upgrade too, I don't see why I'd ever need to. But even if they last me 5-10 years, that's still a very long time.
And if you want to take it even further, listening to music on drugs is incredible. It's really a transcendent experience. Getting baked and listening to music makes music sound like 4 times better. Pairing that with decent audio gear is a 600-700% improvement, which is nuts.
But it doesn't stop there. If you're open to it, listening to music whilst tripping on psychedelics is absolutely fucking incredible. It's literally the best thing I've ever experienced. I'm not exaggerating when I say music sounds like 20 times better on it. It's insane.
So if you love music but haven't yet invested in some decent gear, do it. You're missing out.
