A bit skeptical, I was the same when I first kept the things in hand. They should stick to their ears? The earloop are basically flexible so that it can be individually adapted to the ear each. The plugs ear, then press the strap around to somehow around the ear. Sometime sit the plugs since then, where they should be. The first sound test is promising; Good, full, round sound. There is no question here of the OMX 185 has its real strength and provides the cheap competition quickly in the laces.
But: Who actually thinks, with the OMX 185 can also sporten - forget it. The curved temple stay while jogging not in position. They constantly lose their grip, the plug slides out of the ear. Time right, sometimes left, sometimes both at once. Running repeatedly bend the bow to his ear and push the plug in his ear - and after a few moments the strap with a screwdriver and the plugs are out of the ear.
I have the OMX now since 4 weeks and thought at some point you will find it out the position in which keep the plugs. But think. Any bets: No Sennheiser OMX 185, the designer has ever worn during exercise, for such they are totally unsuitable. Upon jogging simply not in the ear.
For the good sound I give smooth four stars. Since the OMX 185 but advertised as sports headphones and sports completely unsuitable - depreciation on a star. Sorry, Sennheiser, which was nothing at all.
