I needed to pick up a pair of headphones for a quick road trip pretty quick so i ran into the store, looked around and narrowed things down to either SkullCandy GI's and Sennheiser HD212's. I ended up leaving with the GI's but having read so many reviews online about both I'm not sure if i should stick with the GI's or exchange them for the 212's... I should mention i'm obviously looking for sound quality and so far the skullcandy's sound allot better than what i'm use to. But im not an audiophile so i wouldnt know much.. Furthermore i'm also looking for isolation and the GI's aren't as good as i thought they would be, but than again from what i've read while some find the 212's great in terms of blocking out external sounds, others finding them lacking as well... So your thoughts??
