Excerpt: After spending way more money than the cost for a pair of SIE2i for quite a few "low cost headphones" this is the way you want to go! Headphones just work, sound is good and the most important thing: They stay where they are, you don't have to constantly adjust them.
Pros: Comfortable, Compact Design, Easy To Use, Great Sound Quality, Quality Microphone
Summary: Let me start by saying even though I own other quality Bose products, and I knew I was paying for the Bose name and therefore the QUALITY OF SOUND, I was nervous about the price just for sport headphones. However, after only three short days, I am in love!
Summary: When it comes to Bose you would expect world class sound. I admit I am a man that is picky with his headphones, very picky. I do not like the headphones to get in the way of when I run or lift weights. The good thing about this product is that the reebok arm band allows just that.
