User Impressions & Discussion

• The sound is often described as similar to the KPH40 (another Koss model) but with slightly more bass.

• Very lightweight and comfortable for extended wear.

• Because it is open-back (i.e. non-noise-canceling), ambient sound will be heard.

• In reviews, the maximum volume is noted as being “louder than I would want to listen to” with minimal distortion.
