Pros Very comfortable and secure fit. Sound quality among the best I have heard at this price for a non-noise-isolating in ear headphone.
Cons Does not block external noise - which could be a pro for some.
Summary I use these every day to listen to my iPod to and from work and I can definitely say these are a significant upgrade for anyone using standard earbuds, with very good sound quality and a very comfortable fit. Brings out subtle details in music and improves bass response with a much more balanced sound. Most Bose products are arguably over-priced relative to the competition, but this is an exception. As noted these are not noise-isolating, which I actually prefer. In their category I think they are one of the best in-ear headphones out there. Highly recommended!
Pros I have used Bose for about 5 years; I listen to music constantly and these are the most comfortable and best-sounding in-ears I have found.
Cons In 5 years I have had to replace my headphones five times. The plastic sheathing on the wire cracks and splits very quickly at the junctures with other elements. The newer ones which I bought 9 months ago have cracks at the Y-junction and at the bast of
Summary If the wire quality were better, I would be a lifelong devotee even with a higher price tag, but as it stands I'm looking for others with comparable sound and comfort.
Pros sound is good, fit is good, light and great for working out.
Cons gets painful in ears after a period of time (for me about 30 mins) sound quality could be much better
Summary if ur gonna spend a 100 dollars on earphones...DONT! save up a bit more and buy other bose headphones (the ones that go around ur ears AE2) the ones i want to buy after i try selling these ones :P
Pros Comfortable, can sound ok if you can hear them
Cons You cannot hear them on a city street, subway or anywhere there is ambient noise.
Summary The reviews really downplay the fact that in a subway or city street you cannot hear the music at all. They could sound like a pair of $30k nautilus speakers but it wouldn't matter. The openness is way to open. Even in quiet I find the sound to be very harsh, low end weak an mids non existent. Just get a $20 pair of skull candy at least you can hear them.
Pros Great fit and comfort
Sound quality is a 7 out of 10
Cons Poor quality and engineering. Last less then six months for the two pairs I purchased.
Summary These do not last long at all before the cable frays at the ear piece. I expected more from Bose. Do not buy if you plan to use them regularly as they will not last.
