What Buyers Say
Koss Utility 21299195352
65 out of 100 low confidence 7 reviews
The Koss KEB90 earphones deliver clear highs and punchy bass when paired with a DAC, but many users find the stock sound too bright and lacking bass without one. Build quality is a mixed bag—some appreciate the detachable cables and included tips, while others note flimsy wires and uncomfortable foam tips. Overall, they are a good value for the sale price, especially for those willing to use DSP correction or aftermarket ear tips.
