Sennheiser HD 660 Headphones

These are so worth the price! They are soft and comfortable around the ears. I can hear clearly and separately of each orchestral instrumentation into my Logic Pro X software. Nothing compares to theses headphones even though they are expensive. They are expensive because they are made with very good quality and sound.
