Seeking recommendations from headphone experts (that would be you). I don't want to overlook any options. My needs are: ~$400 to $450 Over ear, closed back (will use at work) Listen to indie rock, electronic I'm coming from a string of bad luck with headphones. My NAD HP50 (excellent mids) broke after 1 year. I am now on my third pair of Monoprice M565C. The M565C ended up being a much better performer than the HP50 (which surprised me) but the female cable inputs in the earcups are so loose that audio drops with any head movement. I've tried multiple cables and sources with the same issue. I love their sound but can't continue using headphones with such simple QC issues. I'm increasing my budget a bit in the hope I get something that sounds great and lasts. So far, I've researched the following: Fostex TR-X00 Mahogany -This is my leading contender but I'm a bit concerned that the semi-closed design may leak sound and annoy coworkers. Is this an issue I should be concerned about? Audioquest NightOwl - Concerned that these are increasingly difficult to find to audition. These seem to have a love it or hate it reputation. Oppo PM-3 - The M565C turned me on to the speed of planar drivers so going back in time for a used or new PM-3 via eBay may be an option. Some concern with build quality -especially as there is zero chance of support. Thanks for reading! I appreciate any advice you can offer.
