Chosen after comparing models intra in the range 80 to 100, I set my heart on this model Hifiman RE-400 after reading a glowing article on DigitalVersus. While the article reported a slight predominance of low, I was surprised at the clarity of sound and delivered the perfect balance between the frequencies. I personally would come almost regretted that low are not actually put a little more forward, but it fits with the various equalizers of my appliances and is therefore not an insurmountable problem. The finish of the product is extremely attentive and the multitude of tips offered makes it perfectly adaptable to all ears. Excellent value for money and therefore a recommendation!
