The total disappointment followed: The SHP 8500 sounds compared to SHP in 2700 and as the centers had been removed. Some songs (eg Shakira - Waka Waka) clink the centers. Bass has a presence, heights are available, but the sound is anything but round. Besides, I always had with this model feel that the left earphone was a little louder than the right. The SHP 2700 sounds in comparison, much fuller and rounder, there is no clash and it costs less! Last of comfort when SHP 2700 is even better.
Conclusion: It does not always make sense to take the better model of a manufacturer.
