I'm looking for headphones that I can use plugged into my PC at home, and wirelessly to my phone on the go. I already own Audiotechnica m40x's and Philips shp9500's, and while I do prefer the wide sound stage of open back headphones, I know that closed back would be better for travel. I have tried on the Sony XM4's and while they were comfortable and seemed to have good imaging, a friend suggested the Sennheiser Momentum 3's, as they apparently have a more neutral sound and better construction. I prefer a neutral sound as I listen to a wide range of genres, and did not like the V shaped curve of something like the Beyerdynamic dt990. I work at best buy, and can take advantage of my employee discount for any brands sold there, but my budget is somewhere around the $300 mark, so if they are sold by somewhere like amazon, keep that in mind. Any questions you have I would be glad to answer, and I know this is a strange use case, but I'd like to just have one pair of headphones for all my uses, instead of spending more to get one for home and one for travel
