Hi, I’m new in the “headphones” world and I usually bought the first cheap option with good reviews on youtube and never really informed myself. My current headphones (Anker Soundcore Q30) are almost dead and I want to make an informed choise about my next one. However I feel like there are a lot of things I know nothing about.
For example I read a lot of good things about Sennheiser but the first pari of headphones I saw in my price range (ACCENTUM) have 37mm drivers. My Soundcore Q30 have 40mm drivers and I always thought that “the bigger the better” for the driver. From what I heard, however, the ACCENTUM are consider higher quality than Soundcore Q30.
What I’d like to know is: what should I really look for to understand the quality of the headphones?
I’d mainly use them to listen to music (some Metal, Punk but sometimes Rap, Classical or movies and videogames OST) in my house or outside (so good ANC is always appreciated).
Try them. That's the only way. Go to an actual physical place (i.e. a store) and see what you like and don't like about the models there.
Then you can ask for specific advice using those models as a reference.
