What Buyers Say
Koss Utility 21299195352
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.

Overall, they are a good value for the sale price, especially for those willing to use DSP correction or aftermarket ear tips.

- Detachable cable design
- Comfortable silicone tips
- Good value on sale
Cons
- Bright sound without DAC
