Pros: amazing SQ, great bass
Cons: uncomfortable after a few hours
This was my first pair of over ear headphones. They surprised me a lot because I paid the equivalent of about $30 and got a whole lot more for that in terms of sound.
I tried them out in the store, before purchasing, on my Samsung Galaxy S1 and eventually used them a lot on my work computer. Amazing sound quality! They have great bass, really punchy and deep, especially after about 20 hours of usage.
The only draw back is that they get a bit uncomfy after more than 2 hours of listening. I wear glasses and the cups press really hard on my ears. I have to take them off and have a break every now and then.
They also leak sound at high volumes, but it's not anything dramatic.
Overall, these are a great pair of cans. I keep them as a backup. I've upgraded in the meantime, but I still come back to them now and then and they're still great.
