I upgraded my Sennheiser HD 660S2 wired headphones with a more powerful iFi DAC to unlock the highest quality audio — but I honestly wasn’t expecting these results
I complemented my Sennheiser HD 660S2 cans with the excellent iFi Zen DAC 3 and discovered that not every device benefits from a discrete DAC.
I upgraded my Sennheiser HD 660S2 wired headphones with the iFi Zen DAC 3, hoping to unlock the highest quality audio, but my expectations were not met. The Sennheisers, while premium, do not have their own DAC, so I believed the iFi would greatly enhance the sound. However, the results were mostly incremental, with only a 5% improvement in overall audio quality.
The mid-range frequencies, treble, and low-end performance all showed slight enhancements, but nothing substantially transformative. While the iFi made the bass sound more impactful and helped maintain vocal clarity, the overall improvement was not as dramatic as initially anticipated.
