Looking for some functional earphones that will look hot with your summer attire but not break the bank? Radius has a sweet line of Ultra-Light Aluminum Earbuds that come in a slew of bright colors and boast noise isolation. They only cost $30 a piece and include three sizes of silicone fittings to ensure a snug fit — great for those with tiny earlobes.
And not only are they iPhone compatible, but they feature a U-style cable so that you have the extra length if you need it and a matching cable that's shorter for things like trips to the gym (so you don't get all tangled-up on the treadmill like I have!).
