Pros: FUN, great value for money, very powerful bass, decent mids and highs, very comfortable and light, sturdy, great isolation, removable cable.
Cons: Bass tends to slightly overpower mids and highs in bass heavy songs, looks cheap, thin cables.
These are my favorite headphones. I've had them for years, I don't even remember when I bought them, but still to this day, every time I put them on, they put a big smile on my face.
I own headphones such as Sennheiser HD650 and AKG Q701, and have owned many others much more expensive than HD212's, but none of them were as fun.
HD212pro are in my opinion one of those headphones which make you forget about sound neutrality, or soundstage, or imaging, etc...they just make you have fun. Any music, from techno, dubstep, rock to classical and jazz sounds great for the money, and that constant smooth bass envelops you. No other cans that I have tried can produce as much bass as these. I mean, HD650's bass feels thin after listening to these for a while.
Overall, great set of cans for the money.
