They've got big quality bass with a lot of texture while still sounding very open and wide. The sound is just aggressive enough to have a good sound without hurting your ears. Cymbals have a little bit of a fizz to them, but they sound amazing and clear. The vocals are as if JVC and AT had a baby. They are throaty and deep while being whispery and sweet. Female vocals still edge out male vocals slightly though. I like the sound because it is bright and warm, it's definitely not neutral it is very colored. It does remind me of Audio Technica in a lot of ways. It's like everything is forward while still retained depth, width, and openness which is what is really blowing my mind.
For my nephew's birthday, who's a fledgling head-fier, I originally purchased the VSD1S for him as a step up from his Monoprice. But when I asked him his sound preference, he mentioned liking a warm and open sound signature. Thinking the VSD1S might not jive with his preference (and it might not arrive in time for this weekend), I searched this thread and Joker's reviews thread for an IEM to fit his taste.
Lo and behold, your post pops up word for word on what he wanted. So I purchased the Gratitudes and thanks to Prime Shipping it'll arrive today, plenty of time until the weekend. So tempted to open it up and have a listen but I'll resist. Hope he likes it not only for the sound, but also for the looks because EW&F was beyond his time (he turns 22).
As for the VSD1S, I guess I'll hold on to it and complete my VSD1 collection along with the "original" and the LE.
