i had incredible experience with these fantastic headphones. Using these headphones combined with a Aurium tube amp By Pathos Acoustics is a fabulous listening experience, every sounds is located where it should be. You can stand to listen to music for hours and hours and you will not notice you wear these headphones super light. The sound is crystal clear and pure, turning up the volume even at high volumes makes the headphones at peak without ever distorting. the materials and the coupling of the parts are perfect, never a creaking. Choose these headphones combined with a hi-end amplifier, relax and enjoy your music, let the gossip to others.
