Harman Kardon Soho Review
Delicious design, superb sound
The Insides That Count
Since beauty only runs skin deep, we put the Harman Kardon Sohos through a day in the lab. Test after test revealed praiseworthy quality: The Sohos tested with a well-balanced frequency response, very low distortion, and acceptable tracking results. These on-ears offer high quality from the inside out.
Great sound to please a variety of listeners
The great thing about the Sohos' frequency response is that it suits casual and refined listeners alike. That's because these on-ears don't put too much emphasis on bass, but there is just enough power in that low end to maintain the rich, deep bass notes that so many listeners crave. Not only that, but mid and high frequencies are allotted plenty of emphasis as well.
The final result is a soundscape with prominent bass support, but one that retains lots of detail and volume in the mid and high portions of the range as well—full, textured sound.
Clipped harmonics and extra garbage won't rain on your parade.
Another performance highlight under the Soho's belt is the distortion test. These headphones produce very little distortion across the board, with no audible issues on the whole. Note that the spike in the sub-bass range is nothing to worry over, given that human ears are so insensitive to frequencies this low.
Be sure not to increase volume past 111dB, though—this is not only an unsafe volume for extended listening, but will also increase THD (total harmonic distortion) to upwards of 3%.
