Do the Pro 900s continue to soften with burn in (not just a couple hundred hours but many many hours)?
Long story... A friend was looking for headphones, and I have a few and a few amps, and UAPP with tone boosters Morphit. He was looking for something with more weight in the bass, and detailed treble (V shaped). Nothing I had got him going (K7XX, HD650, HE 4XX - Valhalla and Magni 3 at the time). So I started sorting through Morphit to find some phones for him. Not gonna say Morphit transforms one phone into another, but it does give you an idea of the sound signature of different phones, The soundstage, speed, etc., no. So came across the Pro 900s morphed using the HE 4xx. Thought he might like em (Heck I might like em). Auditioned it for him. He Liked it. eBay find for like new $165 or so. Damn, I liked what I heard when I got em. Found another set for me about the same price, but... They were really really well used (or at last really really used!). No ear pads, Monster 3.5 to 3.5 cable, Head band pad is flat, not just weak - but worn out flat. A coupe of pieces from his kit, spare ear pads, 1/4” cable (finders fee - with his approval of course). And, well these phones just sounded worn out compared to his. Fast forward a couple years - I buy another set of used Pro 900s off eBay for a set a little more $, but still under half price retail, to use at work (new job in a cubicle instead of private office) . Very little use, probably not burned fully in yet, Badges still had protective plastic on em. I got that WOW factor again. Day and night between the old pair and these. So I’ve had three used pair through my hands (two still here), two with just enough use to start the break in and one that are fully broke in (or maybe worn out), and that’s the question. Do these continue to loose their “dynamics”, or did I just get a pair that are plain just wore out? Or am I just really liking half broke in Pro 900s?
By the way, even though the worn pairs headband pad is flat, the badges looked like they had been drug behind a kid’s bike through the dirt, and who knows what the ear pads were like, the frame on these are still solid - built like a tank? Ya!
