I actually bought headphones just as quick replacement because my Klipsch S4 unfortunately had a bad contact (after less than a year!), The in-ear. Of course not compare concerning the sound, but for 10 euros you do definitely nothing wrong. For the price, the sound is really unexpected good. I find the in-ears compared to other quite hard, but you get used to it. Whether I like of course a matter of taste. Another note: The earphones now hold since December 2012. So for over 1 1/2 years. Because of the price, of course, I pay attention not so much on the headset, which is why they are abused in the depths of my backpack from Drumsticks often times disappear in your pocket or. Still intact. As my former Klipsch and Sennheiser Inears (time for 100! Euro) despite meticulous accommodations in Cases etc. have never lasted this long. For the price so really top. As can the large cut of what. My next purchase will be so again by CSL since both my external hard drive enclosure and HDMI cables from CSL has never causes problems (not like other manufacturers).
