wow, the props. niceeeeeee. Better than headphones in the 1000$ range! 
I’ve ordered these and i’m sending the Sendy’s back, for a nice 300$ credit back to my card
Its good to have confirmation that they are as good as Z says. I want to buy headphones in the 1000$ range but cant afford it. this is the next best thing! I love the detail on the Aiva’s and the sound is just fantastic. I love the forward sound of them. A little too aggressive though so looking for a good profile to EQ them down or a good mod. Now that Monoprice are making them i might get one. Sendy being a more obscure company. Monoprice has a history of their headphones being moded.
I agree that these are important headphones. Maybe they can force the industry to drop their prices or make better headphones.
Looks like its time for you to take the plunge Mon
