Excellent quality headphones.,
This review is from: Klipsch Image S4 "II" In Ear Headphone - Black (Electronics)
There are numerous different types of in-ear headsets and you should be very careful to choose the ones that you exactly want.
These - are in-ear and are much less cumbersome than over-ear ones, are very comfortable to wear, fit nicely into most ears, isolate you from surrounding noise effectively and have great sound quality.
Please note that these do not have the remote control & microphone on the headset cable but it is widely believed that not having this facility yields an improvement in sound quality - this headset certainly delivers high quality sound.
However, if you do want the remote control, then buy the alternative model of Klipsch headset which includes this facility. Although the sound quality may be very slightly compromised, you may feel that having the remote control facility is important to you.
All in all, a very good and comfortable headset, especially for listening on the move. Consider the alternative model if you want the remote control & mic facility.
