"Worked great for about 2 years"2.5 starson by john070171
Pros: Great sound, fit my ears/head perfectly, did not fall out while running, nice to have expansion cord for plugging into other devices, case a nice extra to keep cord from getting tangled/mangled.
Cons: Right ear died right around the 2-year anniversary of purchase.
Summary: These worked great for about 2 years, but I kind of like stereo sound :) so after the right ear died, I'm going to try a different brand. Had Sennheisers last time, done with Sony for now, think I will give Philips a shot.
