I know what you’re probably thinking.
“Alex, why aren’t you comparing the AKG K371 to the Audio-Technica M50X?”
Because there’s not enough to talk about there.
The K371 so thoroughly trounces the M50X that there’s no real reason to buy the latter headphone anymore, in my opinion.
They’re both targeting similar design goals and usage scenarios, but the K371 is just better at every turn. It sounds better. It’s more comfy. It has a sleeker design and a comparable set of cables, but with a sturdier connector.
If you’re considering an M50X or M40X, consider a K371 instead.
Beyerdynamic’s DT770, on the other hand, is its own beast. It’s a headphone I’ve loved for a long time, and it has its own distinct character that will put some people off. But that character has also helped it stand the test of time on the market.
