HiFiMAN RE-600 In-ears @ techPowerUp
 

HiFiMAN's newest high-end in-ear gets put to the test. The RE-600s are a beefed up version of the RE-400s we loved. The price has also been hiked up to $399, making it just as expensive as several great in-ears, like the UE900s. We test the RE-600s to find out whether the asking price is justified!
