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: These headphones are great; I can barely feel them when they're on and the sound quality is great, just what you would expect from Bose. I haven't used the armband so I can't comment on that, but having a short or long wire is much more useful than I thought it would be.
Summary: These are the best earphones for comfort I've used they just do not fall out , you forget you have them in as they are so comfortable. The sound quality is more than adequate but not the best I've heard. I would still buy them again over any other just because of the comfort.
Summary: These are super amazing! I have had Bose IE's for about 5 years now and my old ones are still going strong but, the in line volume control lured me, not only that I have used these on my iPhone 5 and my Ipod Nano, brilliant on my iPhone can answer calls seamlessly and when playing music can skip...
Summary: Whilst I'm not sure I would be willing (or indeed be allowed to) fork out £130 of my hard-earned on a set of earphones, I was delighted to receive these through the ever excellent Vine Programme.
Summary: Bought these for my hubby for his birthday because I already have a pair of the MIE2i which I love. Not surprisingly, he loves these SIE2i headphones. He finds them really comfortable to wear, light and non-restricting, especially with the extension cable.
