best bang for the buck is buying used.
Bang for the buck ... high Q/$ ratio.
If money isn't an issue it’s not too difficult to find audio gear that sounds really good. But what if we don’t want to break the bank? Then it can become harder to find that one gem. But it’s not impossible, sometimes you find an item that sounds much better than its price tag suggests.
I bet most of us once had such a 'wow' moment. I had mine with my earbuds. When I needed a pair I set my budget at $100. I did some reading and found multiple reviews on the KZ ATE, most of them claiming they sound better than pairs ten times their price. And the fun part was … they’re just $10. I ordered myself a pair and kept my expectations low, worst case there was just $10 to lose. But guess what? Every time I put them in they put a smile on my face and I’m amazed how good they sound.

That's the idea with this thread. Please share with us a 'wow' moment you had when you found a product that amazed you with how good it sounds, given its price tag. Preferably backed with a few links that confirm it's not only your own opinion.
