I have been thinking about buying one of these headphones and I would like to know which of these would be the better choice. The cheaper version has really good sound, the more expensive version is more portable and easier to store. Not sure how the sound compares though. So I’m not sure which to get. Things I like about these headphones 1) Great mids, large soundstage. 2) Instrumentals sound great as do vocals. 2) very light weight and easy to carry around. 3) great passive noise reduction. 4) I hear Bose has great customer service in the event that something breaks down. I mostly listen to things like Adele, Alicia Keys, Amy Winehouse and other singers. I also listen to country and some Rap. If you have suggestions that would be better, feel free to chime in. But I will probably get the Bose as they do sound great. If I were to choose something different, it would have to be cheaper and include all of these advantages.
