Deciding between Grado SR60i, Nokia Purity, and Beats Solo HD. I've had the Beats Solo HD for about 1.5 years and they're starting to fall apart and sound quality is getting bad. So i'm thinking about getting new headphones. I listen to hip hop (not that radio rap garbage though) and some classical music when I'm studying. However, I mostly use headphones when watching movies/TV shows on my MBP and listening to lecture recordings. That's where my primary use of headphones comes from. I'm not really concerned with the bass, but more about clarity of sound and decent mids and lows, ect (whatever that means ). I would also like headphones that have some decent noise blocking capabilities for when I'm studying/listening to lecture recordings. Before the Solo HDs, I only used the Apple earphones and other <30 dollar earbuds so the Solo HDs were a big upgrade for me. Reading review's i've heard great things about the SR60i. The price point is attractive too. But i've read some reviews suggesting there is significant sound leakage. The Nokia Purity (http://www.amazon.com/Nokia-Purity-On-Ear-Headphones-Black/dp/B0074F5F4U) are new on the market, but from reading some reviews they offer pretty good sound quality too. They are attractive headphones with nice colors. Also, I think AT&Ts selling them for $99 and they would go great with my new Nokia Lumia 920. Reading Wilstreak's review on Amazon for the Nokia Purity headphones, he suggests that these are better than the Solo HD and even the SR60i. Based on your experiences how are the SR60s? How is the sound leakage? And which headphone set would you choose considering that Nokia Purity's are selling for $99? Thanks in advance.
