I use these earphones with small earbuds. To really "to carry him invisible, the plug must be pushed deep into the ear canal, which goes, but it needs some time of familiarization. That being said, is the comfort then pleasant. I use the earphones in combination with a Nokia N8, which I wear on a belt. For this, the cable length is ideal, and the winding of the cable allows me to take the phone once in the hand when the cable is worn under a jacket or sweater. The sound is much quieter and duller than but still clearly understand conventional headphones (even with telephone calls). Since the invisible use was the purchase criterion for me, I admit, despite the aforementioned limitations 4 stars
