Are the Sonomax PSC-250 Sculpted eers the best ear-buds I've tested? Yes. By far. Of course, that's a short list right now. But even when comparing them with my full sized Denon AH-D1000 and Audio-Technica ATH-M50 headphones, the Sonomax come out on top. They may not have the flattest frequency response, but they have a very full and rich sound and is a joy to experience. The molded earpieces means that you've got a set of earbuds that are tailored just for you and, paired with the earhooks, will take an act of extreme violence to get them off your head. If you are looking for high-end audio even when working out, check out the Sonomax PSC-250 Sculpted eers. You won't be disappointed.
