I’m always buying $20 headphones from Target that break in a month, but for those who care about their audio experience, these reviews done by David Mahler, a “headphone guru”, will give you a good idea of what to purchase next. Individually reviewed, he gives the good, the bad, and the ‘eh’ on each headphone. Mahler also rates the product with a letter grade based on the price so you don’t waste money on just an ‘okay’ product anymore. [Source: Head-fi]
