وَإِذَا تُتْلَى عَلَيْهِ ءَايَـتُنَا وَلَّى مُسْتَكْبِراً كَأَن لَّمْ يَسْمَعْهَا كَأَنَّ فِى أُذُنَيْهِ وَقْراً
(And when Our Ayat are recited to such a one, he turns away in pride, as if he heard them not -- as if there were deafness in his ear.) means, when these Qur'anic verses are recited to one who is fond of idleness and play, he turns away from them and does not want to hear them. He turns a deaf ear to them as if he can hear nothing, because it annoys him to hear them since he gains no benefit from them and has no interest in them.
