These are DIY sweet cheeks of wood that Felib put together using drivers from somewheres in the interwebz. Let's start by going through the process of unboxing these coconuts: @#$! But it's all good, eventually I was able use my skillz to pry open the virginal box. And Howling Shite are these Big. Materials are top notch and workmanship is way and beyond what I would expect from a DIY can. It's just too awesome. The cans are set pretty wide. Think Abyss. Cans are comfy but a little on the heavy side. This is likely due to the materials which are top notch. Cups are very nicely finished. Cable is also nicely braided. Now as far as the sound, I wasn't expecting what I heard. Awesome mids. Treble was also pretty good. But the mids were very well executed. It is often the case that things go somewhat wonky with closed cans. Not so with these. These are bassy. And they are not uber-clean in the lows. But they are very engaging and very musical. These marries really well with the balanced mids. Again. These are NOT SHIT. Very masterfully done. Measurements: Frequency Response Distortion Right Distortion Left CSD Right CSD Left I would like to point out that the channel balance is remarkable. According to Brandon, these are tuned by ear, which IMO is quite an accomplishment.
