I should be studying for exams but I'm temporarily brain dead so need to talk about something more fun than statistics, even for just a bit. @Ainsworth (awesome name by the by) dropped mention of the KLH Ultimate One headphones in the Verite thread and my curiosity was piqued. More than a passing resemblance to the Klipsch Heritage HP1 that never made it to production from the gimbals down and the fact that the person spearheading this project was David P. Kelley, formerly of Klipsch, got a raised eyebrow out of me. Eh, nothing but supposition at this point, but the resemblance is uncanny (even if they stole the headband design from Focal instead of Klipsch). MSRP is also close to what Klipsch was targeting. Tyll's video from CES 2017. See around 2:00: One difference between this and the unborn Klipsch is that while the HP-1 was meant to house a 40mm biocellulose/biodynamic driver, the Ultimate One houses a 50mm pure beryllium one. Big driver in a housing designed for a smaller one brings Sony MDR Z7 to mind— I liked the Sony cans, but not really enough to buy it despite my brand fanboyism and appreciation of the stellar build. Found some measurements of the Ultimate One by Brent Butterworth, which is a name people on here might be familiar with given his history in the published audio space. He's got a database of other headphones to compare against including the HP-3, and while I may not necessarily agree with how things look on his coupler or editorial comments about how the HP-3 sounds "normal" (HAH), it's a useful data point nonetheless. Do note that the Focal and Klipsch measurements have two sets of FR, he was in the middle of a transition from KB0065 simulated ears to KB5000 and wanted to keep both for posterity. The KLH only comes with KB5000 measurements, and yes the differences in FR are significant enough to warrant notice: KLH Ultimate One Measurements: https://www.soundstagenetwork.com/i...-ultimate-one-headphones&catid=263&Itemid=203 *third image in link shows FR comparison with HD6XX, HE400i, and the Nighthawk Klipsch Heritage HP-3 Measurements: https://www.soundstagenetwork.com/i...heritage-hp-3-headphones&catid=263&Itemid=203 Focal Clear Measurements, for something more normal-sounding: https://www.soundstagenetwork.com/i...3:focal-clear-headphones&catid=263&Itemid=203 No KB5000 measurements but the bass response should be similar— the way the bass drops off into the midrange is reminiscent of the Bowers & Wilkins P9, which I've been meaning to listen to: https://www.soundstagenetwork.com/i...-p9-signature-headphones&catid=263&Itemid=203 Has anyone here gotten ears on these yet? Just based off the measurements and guessing what sticking a large Be driver in a small housing might do kinda puts me off, but I'm still gonna try getting ears on these when I can, maybe see if I can generate squiggles of my own. EDIT: Some grammar and FR added to save clicks. For blue and orange traces, blue is old pinna while orange is new (which was used for the KLH).
