I’ve got a pair of Sennheiser HD580. They work for me. Recently, I tried the Massdrop HD6XX (HD650 voice) but they simply didn’t offer me anything over the 580, and less comfort. I also tried Mr. Speaker Aeon Flow closed, and like what I heard but they simply didn’t fit me well and were 7x the cost of the 580!
I’ve got these Nuraphones on their way to try out. I’ve also got a AptxHD bluetooth transceiver (selectable) to go wireless from the BHK preamp.
I’ll report back what I find. Oh, I have no connection but found this review with a link to save 20%, worked fine.
