This review is from: Bose ® SIE2i Sport Headphones - Blue (Electronics)
These replaced an older pair of the Bose in ear headphones. I find lots of in ear headphones very uncomfortable because they are too big, these arrive with 3x sets of silicon ear tips (S/M/L) that mean they will fit almost anyone. These are great for running the revised design means the tips don't fall off and the headphones stay in your ear. The short cable and extension cable is a great idea that stops you getting tangled up in the cable if you have your device in the supplied armband or a breast pocket.
Why 4* - the sound isn't fantastic. I suspect the noise cancelling equivalents will be much better, but at twice the price. These are good value.
