There are many mid-priced earphones to use with your iPhone. Sony MDR-EX90LP is a good choice considering sound, design, comfort, and bass response with Sony quality. And there is a low-cost way to get this high-tech from Amozon offering it for as low as $66.27, and currently in stock.

But I should warn you that fake Sony earphones is also on the market. And you may not understand which one is the original. Actually the fakes sound louder than the original but the quality of course is so bad that you can easily see the difference. Before you buy, please read more from google.
