'Good build quality and nice running specific touches. Definitely recommended!'
Strengths: Good sound quality Durable In line remote and microphone is great with iPhone and Nike+ app
Weaknesses: Nothing really. Cord can be a bit of a pain if you lose the clip because the mic has a tendency to bounce at face level!
Overall: This is my second pair of Sennheisser sports headphones after my acidic sweat corroded my first pair. Really pleased with all aspects of this pair. Had them for nearly 2 years now and run 4-5 times a week in that time! Still going strong!
