One of the best values in full-size headphones, the HE-300 utilizes dynamic drivers and low impedance so they are easy to drive on a portable device (i.e. iPod or iPhone) but can also be used in a high quality hifi system. The HE-300 combines the advantages of a traditional dynamic design such as 93dB sensitivity and high output yet offers a familiar sonic signature of HiFiMAN’s top-of-the-line reference models.
