A wonderful review on CNet by the very well respected Steve Guttenberg. He has a lot of great things to say.. Here's my favorite: The Remastered let me hear not only the music, but hear the music played in the room it was recorded in. I kept having "oh, wow" moments as I moved through my collection of well-recorded high-res music. https://www.cnet.com/news/for-your-ears-only-ultimate-ears-reference-remastered-headphones/ Check it out.
