I've had the opportunity to listen to these a bit, so I want to post some impressions. I'm in no way an expert in the headphone world or really an audiophile - this is the first set of cans above $200 I've heard and my only other reference point is a pair of Westone IEM's - so please bear with me. Though hopefully this nooby perspective can help my fellow audio novices. At first listen, to be honest, I kinda felt the same way that the one guy who thought his set of cans had been blown somehow - I'm not sure what it was, but it sounded like something was wrong. The thing that was wrong must have been my ears, though, because I got accustomed to them and I think I'm sold. They're so CLEAR. The bass isn't booming, but the attack is so fast that it has thump, especially in electronic tracks like Madeon's "Imperium". I think my ears have accustomed themselves to the balanced sound some and that helps - I've been used to bigger bass and these did sound bass-light at first, but a little EQ (I use the Rock or Latin presets on an iPhone 6 and iTunes mostly) and some acclimatization have settled me in. Jed Whedon's "Drones" was a pleasure to listen to - every instrument and sound is easily distinguished and sounds clear, crisp, and tight. Watching movies brings out some extraordinary detail. I watched the Podracing and duel scenes from The Phantom Menace and the quality was amazing, though the soundstage is small. Gaming can sometimes feel anemic in my view because the bass isnt boosted, but I did notice a lot of detail I hadn't heard before, and perhaps some EQ'ing or amping could solve the issue of low bass - I don't yet own an amp. The build quality is excellent on these cans. They look and feel like a premium product. As part of my testing, I took them down to the Apple Store to compare them against a couple other pairs of headphones I'd heard were good: the M&D MH40's and the Bower and Wilkins P7's. While both sets had noticeably bigger bass, they sound muddy in comparison. They're easier to drive than the PM-3's and I felt the P7's were more comfortable, but the PM-3's had better isolation and the MH40's made me feel like there was a strange pressure differential around my ears that I didn't like and were difficult to attain a good fit with for me. My access to different test units for headphones is pretty small, but out of these three, the PM-3's won based on their clarity and comfort, and sounded like enough of an upgrade from both sets that I feel like I'll be hard pressed to find a dynamic can that can match the PM-3's clarity. Overall, for me, the PM-3's give you great clarity and level of detail at the cost of some volume and boom in the lower range. For me, that cost is worth it. I'm sincerely happy with these cans and will probably be purchasing a pair soon. Thanks so much to JiffySquid and Oppo for this program! Edit:Speaking of not having an amp/DAC, has anyone tried pairing the Oppo PM-3 with the Audioengine D1 or a similarly priced unit? It looks to have what I need and I'm curious to know if anyone could tell me how they pair.
