A:AnswerI compared these for a couple days with the Sennheisers and found that the Beoplays had more clarity in vocals and drums, but the Sennheisers had a bigger sound stage and more immersive sound. I had trouble deciding which ones I liked best. I ultimately chose the Sennheisers, but you can't go wrong with either one, just personal preference.
A:AnswerYes they work with iwatch. There is a video on YouTube showing E8s with a series 1 iwatch so if you have that or a later series, you will be good to go.
