Chiming in a month after getting my HD650s and a few weeks into using them as primary headphones. I have to say, the Bifrost+Lyr combo with these is pure bliss. Vocals are just fantastic. I probably have easily 100 hours of head time with them already... I'd say 3-6 hours a day on average, in one month is 90-180hours. So even saying 150 hours is a good estimate. Either way... Lana del Rey's latest album, Ride, is a lot of gorgeous vocals... her voice is just haunting with these. It's so real.
Man, it's funny when people say the HD650 is one of the most overrated headphones... because it's totally not. It's pretty much everything I could have wanted in a pair of headphones. I still want some quicker, slightly brighter ones with just as good bass, so I got the Custom One Pros but they had a clipping in the right ear any time I turned it up moderately loud. Turns out I'm not the only one with that exact problem, so we sent them in to Beyer and I'm getting a replacement... asked them if I could get a DT880 instead doubt they will do it, but it never hurts to ask. But when I heard the COPs, the bass was great, better than the HD650 (not as accurate or refined though) but just more pleasing. Except, there were parts in a song that I knew were there, but couldn't hear them very well. The HD650s might be warm sounding, but they are definitely detailed. Whereas the COPs don't actually resolve detail as well, but I can't expect them to for half the price. But I got my DT880s for 180, my COPs for 150... if the bass wasn't so epic on the COPs I'd just return them and buy some DT880s when they drop down from $240... that kind of clarity is awesome. A nice changeup. Just wish they had a LITTLE more bass.
But I'm rambling -- I'm just trying to say how impressed I've been with the Lyr/HD650 combo. It's very pleasing and with a little EQ for more bass punch it blows me away from time to time. Some dubstep just sounds great because they use more midbass than subbass, like Kill The Noise. The song Saturn from their newest EP (Black Magic) has this one part where it just gets to the right frequency... it's like a bassgasm. Love it.
HD650... 2 BIG thumbs up.
And I've been avoiding these forums so I could stop spending money and appreciate what I have. And appreciate I have :)
