Listened to the at Axpona in Chicago and decided to buy them. Must say that the first impression is not fantastic. Came from "bass heavy" SE846 and these KSE1500 is less bass heavy but much more neutral and really reflects the music 100%.

I get tired after listening to the SE846 longer than 2 hrs but the 1500 I can listen to for 3-4 hours and I just realize how much more detailed they are.

Specially listen to Jahres Köln concert - new things that I have never heard before shows up.

Pitty that many iPhone 7´s have problem with external DAC and especially KSE1500. But to get away from it I use Cebntrance fantastic HiFi-M8.

So at first you think they are a bit too neutral but after 30 minutes you will just love them!

They are also smaller and easier to fit in your ear than the SE846.

Tries so many headphones,but just coming back to my 700. Decided to stay with them and my HiFi M8 simply because I love the portability and the sound is great to me.
