"Great upgrade to Bose IE2"5.0 starson by Osa007
Pros: Great sound, durability, cool design, Reebok partnership, and Bose customer service.
Cons: They don't block out sound completely and in really loud environments you can barely hear your music. Price maybe too high for some people.
Summary: I have nothing to complain about because I upgraded to these headphones for about $30 thanks to Bose excellent customer service that offered me that price for trading in my Bose IE2 for repair in exchange for this at a discounted price for being a loyal customer.
What separates these from the Bose IE2 is that they are more durable and do not fall out of ears easily even when your extremely active. I tested them on the elliptical for 45 minutes and it stayed in my ears compared to my Bose IE2 that would have slipped out due to the sweat. Also they are more durable, which is a good thing because I have rarely been able to get my Bose IE2 to last over the 1 year warranty and I used it often. The wires, sound, or something would always give out close to a year of excessive use so I am grateful that Bose came out with this and I hope to be using this for a long time.
