So I'm borrowing a set of YH5k from a buddy of mine and I've got some thoughts. I absolutely LOVE the look of these headphones, they are by far the best looking headphone I have seen to date. Thats kinda where these headphones shine and really only where they shine. The Sound of these headphones stock is just kinda weak. There's very little decay which feels very natural. The only part of the sound i can really compliment is the bass is nice and punchy and the attack of these headphones are pretty on point. The tonality of these headphones is just poor. I took the liberty of measuring the FR of these headphones as a launching point for trying to fix the sound to something more pallet-able.
Out of the box they aren't so bad that they aren't unlistenable I just want to be clear on that,
they just aren't impressive like a $5k headphone should sound.
I tried every pad I have at my disposal with very little luck fixing the upper mids with exception to one set...
my Grado G pads XD.
A little unorthodox but the clamp of the YH5k is enough to keep them in place when on my head.
That mixed with a little front damping using micropore tape lead to suprisingly great results.
If you have micropore tape and some G pads I highly recommend you try this out. My problems with the decay havent been fixed by this but the tonality is WAY better now imo.
