Summary: so they worked, but didn't last.
:-( the rubber ear pads would fall off. I was continually looking for the pads. You can buy spares, but only in packs of 5 pairs for $25 from specified Sennheiser dealers. Do poor design that they could fall off.
Summary: I chose these headphones as i wanted some that were good for running, light, water resistant and they had great reviews. However 5 months later and I'm regretting it! Pros - Very very good sound Cons - I still cant get my head around the design.
Summary: Worked great, but since my phone has a headphone socket at the top, the cable is bent back and soon wears out when running. Result: lost sound in one ear, headphones useless after a couple of months use. I don't know why manufacturers can't give you a choice of angled or straight plug...
Summary: Buena sujeción a los oídos, se escuchan bien y no son demasiado caros, pero tras 4 meses de uso, comenzó a crujir uno de los auriculares ¡y un mes más tarde dejó de funcionar! Ahora mismo los he enviado al servicio técnico a ver si consideran repararlos o me dicen que la culpa es mía.
