Input: I'm a professional audio editor, and I've owned the HM-50 for about 5 months now. At first I was very impressed with these headphones. The sound clarity and noise canceling ability made my music much more enjoyable. While listening to an NPR news show, with their powerful broadcast of traffic around Boston in 2009, it became clear that this was my favorite headphones on the market. For those unfamiliar with FM, Boston's Traffic Radio is free over our wireless system because they can go all day long without interruption.
Output:
Bad review
