For this very reasonable price, finding an equally good sounding iem will be a serious challenge. This time you can trust those rave reviews. The Zero:Red is extremely neutral, detailed and free of distortion. It deserves to be partnered with your best DAC/headphone amp. They are also comfortable. On the other hand, for those people with small ear canals, keep in mind that the nozzle size is bigger than usual: 6 mm.
Initially there was a supply problem at the manufacturer (I suppose) due to the high demand, but those fantastic people at Audiophonics kept me informed at all times. A shining example of how to do business!
