Razer refers to their Pro|Tone m250 ear phones as "Street Style," which, I think, refers to the fact that they are not "in-the-ear" phones. Instead, these phones clip onto the outside of your ear via a hinged arm as shown here:

Quite frankly, after just a few minutes of testing, I knew they were not for me. But since ear phone selection is a very personal thing I asked several of my friends to check them out and tell me how they liked them. I was surprised to discover that at least one of my friends (hi Chuck) has a problem with in-ear headphones and can't get them to seal properly in his ear canal. He says he's never found a pair of in-ear headphones he can use, much as he wishes he could. And he really liked the m250s, saying they offered "pretty good" sound and were lightweight and comfortable.

Personally, I much prefer in-ear phones, the kind that have foam tips to seal in the sound and reject ambient noise. So the m250s missed the boat for me in several ways. First, I didn't find them particularly comfortable. Second, they weren't loud enough and their bass response seemed to lack punch. And finally, ambient noise was much more annoying than with in-the-ear headphones.

The m250s come with a two-prong "jet-set" adapter for use on airplanes with two-prong audio jacks and a soft fabric case with mesh pockets, both shown in the photo above, and are also available in black (not shown).

Last but not least, here are the Pro|Tone m250's technical specifications as provided by Razer:

Frequency Response: 50 ~ 20,000Hz
Dynamic Transducer

Max Sound Pressure Level (SPL): 105dB
Cable Length: 1.15/ 3.77ft
3.5mm connector plug

The Bottom Line

If you don't care for in-the-ear phones and want lightweight earphones, the m250s may suit you. But otherwise almost any in-the-ear phones are probably a better option.
