Sound is really great but had after 8 months a cable break. An exchange is now no longer possible. I had the predecessor and because the cable break occurred only after 2 years. Had I therefore for the S4i II decided in assuming that it keeps longer.
A cable break after 8 months is really weak. Can not recommend this model unfortunately.
If Klipsch to contact me for an exchange, I am pleased to adjust my review on.
Just look at the competition for other headphones.
