Falling In Love All Over Again

There is in every note, weight, and it absolutely captivates me.
Music: Nightcore”ily (Surf Mesa), AC/DC “Thunderstruck”(What can’t you focus on, is what I find, be it guitars, drums, vocals or bass, I can be there.), It’s balanced in a warm way, the bass has an elevation, and the same with the treble, yet the mids don’t take a hit, but sound simply perfect, filled with richness. Sub-bass can be felt on most tracks not as reaching like a DD, but on a few songs such as “Me and Your Mama” by Childish Gambino, there’s a smoothness with richness, and here the sub-bass rumbles and is felt as if it was truly a DD, absolutely amazing. The bass hits hard with a quick punch yet not too quickly so that the ripples are felt, detail is amazing, and there’s a crispness to them, PostModernJukebox, Iron Maiden(Number of the Beast), Opera “The Doll’s Song from “Tales of Hoffmann 2011 performance”, and many more, simply wowed over, the layering and texturing (The Weight!), the width is = in its depths. Different sources and quality, (Flac, MP3, Dac, Youtube, SamsungS9+, though there were mild differences on each, they all sounded splendid and lively, I did not feel any dryness.
Cons: Cord is built great, but way too heavy, switched it out, and fit took some adjusting and getting use to for a proper seal. )2 long of a stem for me, used foams
but I must admit, it’s the music that matters the most to me, and I have that with these, the sound that comes out of them is something I always want to

So good

I’ve had my S7 rui for almost a year now and still loving them and use them for everything they sound great. Lots of detail lots of bass my only regret would be not spending the little extra to go custom
