If you’re sticking with flying I’d buy the A20 rather sooner than later. Best investment in your flying career. Plus they don’t really lose that much value. You could buy a used pair for 700 euros and sell it for 700euros a couple of years later.
You can use them during your whole career: from a C172 to a B737. They’re well built, have good ANC and you can listen to music. What else do you need. We beat them up at my airline and I’ve almost never encountered a faulty pair.
I refuse to fly GA aircraft without them. A pair of DC make my ears bleed, it just takes so much more energy&attention to actively listen trough the noise.
