The iPhone 3G S is here, and it comes with some freebie headphones. We tested these headphones. They're not great, but they aren't nearly as bad as we would have guessed.

The DT 770s are another set of headphones in Beyerdynamic's MANUFAKTUR line. The MANUFAKTUR service allows users to create customized color schemes as well as fine-tune other aspects of their headphones.

The DT 770s are a solid pair of headphones with good sound quality and average isolation for over-ears. We had some issues with fit, like with other Beyerdynamic headphones. Try them on for a few hours before your warranty lapses.

The DT 770s are available for $285 via Beyerdyanmic's website.

The Sennheiser HD 650s are a set of high-end, open-backed, over-ear headphones. The HD 650s implement their open-backed design in an aesthetically interesting way, covering the backs of the ear cups with a grey grate which offers barely any physical barrier between your sound and the world around you. This will create a large, open soundstage, but means the headphones won't be good isolators. The headphones also feature a removeable cord. Since the cord is often the first thing to break, this feature should help extend the life of your headphones.

The HD 650s are currently available for about $500.

The DT 990s recently got re-released under Beyerdynamic's MANUFAKTUR line. This line lets you pick out the headphones' color, impedance, and cord style. These new, improved DT 990s have above average audio quality, but suffer from some significant fit issues.

The DT 990s can currently be purchased for about $350.
