Since I buried it in my review, I wanted this out here since I took a soldering iron to mine. I used copper jumper wires and some lovely 62/36/2 RMA solder. To make my resurrected pair live...
My repaired pair review!
I love the look, and they are comfy. I loathe combo cable and mics so that's still in it's pouch, sorry not sorry.
I didn't want to include this because I've modified them beyond something simple by replacing the stock wires on the cup. I decided to give them a fair shakedown. The source is Tidal MQA, the device Samsung Note 9, a MavisModz cable, and a lightly concave EQ, all other audio processing disabled. I listened to a wide range of stuff... These have the pads swapped.
Chopin, Queen, Daftpunk, Nirvana, Shaggy, The Raconteurs, Migos, etc...
I will say that one thing came to my mind while listening to these, they are fun. The bass is surprisingly clean, but they can boom pretty good. The details are very present, they reproduce things very well, nothing ever feels washed out. Listening to some of the electronic stuff that swings from high to gutter low, they never stumble. On the classical music, they do well on the high notes, not missing a beat to get that thump. These don't disappoint to my ears on Chopin.
I will say they definitely flavour the music but it's not bad, in fact they make me want to listen more. At and slightly above my preferred listening volume there's no sibilance, but they have no issues driving those high frequency sounds. I'm incredibly treble sensitive, so I'd be complaining.
I'm listening to Migos new track on Tidal and the bass hits so clean. It just goes BOOM, and there's no dithering or wallowing, just clean crisp hits. I like it... heh
These have nice pleather pads, especially once you swap them to better pads in the box. I just hate how pleather feels after a bit it gets hot and sweaty.
I need to find pads... I like either humane leather or velour. I think I want to try improving the foam damping in behind the drivers a bit. Tinkering is something these things encourage, I love that there is no clips or glue locking them together.
Summing it up... a great compliment to the HD6XX, I'd think based off what I've read.
Sorry for blithering on about my can't score a franken-pair.
Disclaimer: I went through a very stressful situation with multiple bad pairs. I eventually ended up with these heavily discounted and no warranty. This pair suffered from shorted wiring to a driver.
