User Review: M4U 2 Headphones - Simply Amazing.
After turning on the ANC, connecting the headphones to my NAD C326BEE Amplifier and starting the CD track (Pink Floyd - On The Turning Away) I was amazed at the clarity of the vocals and instrumentals. When I closed my eyes it felt like I was listening to a concert sitting in the front row. Hands-down, these are the best headphones that money can buy. I only wish they came with a longer cable.
