Each of these headphones has to be a compromise between conflicting requirements:
* Low price vs. good sound
* Stability vs. small and light
* Good sound isolation vs. Comfort
Klipsch has managed to close here each had excellent compromise. There are cheaper and more compact headphones as the Sennheiser PX 100-II Foldable open stereo mini headphones (114 dB) black, but they are not as stable and external noise barely starting. There are also small wireless headphones like the Sennheiser MM 450 Travel Bluetooth stereo headphones black, but costs much more and takes all the time battery charges. Compared with cheap goods like Philips SBCHP400 HiFi headphones DJ-style (106dB, 500mWatt, Goldconnector, hi-fi sound anywhere, 2m cable) black of Klipsch offers a decent sound and better processing.
Ideal if you listen undisturbed on the plane or train on the i-Dings music or watch movies wants. As a kind of bonus you can also make calls with the part, the built-in microphone, the remote control buttons work properly with Apple devices, even with newer MacBooks eg for iChat or Skype.
