Summary: I bought these earlier this year for the gym. I have tried lots of sports headphones and the over ear ones work best for me. So these looked perfect. They arrived promptly - no issues there. Seemed to be perfect, cheap, sound ok (but not great) and pretty comfortable to wear whilst running.
Summary: Overall the sound quality is not that good but what's worse is that it does not last long: both my wife and I had a pair of those and within few training sessions one of the speakers stop working! Waste of money.
Summary: As other reviewers have said, the sound is of decent quality, rather than amazing. I bought these to wear while running though. For that purpose, they are fantastic. On sprints, tempo runs and long runs, they stay in place perfectly... so five stars from me. UPDATE >>>> No longer five stars.
Summary: The build quality of the headphone seems OK but I was disappointed with the sound quality which lacked bass. My expectation weren't that I was buying anything exceptional but even at this entry level I would have expected better from a Panasonic branded product.
Summary: These headphones have a terrible sound. They sound just like some very cheap mobile phone, there is no bass at all. I used to have some Sony that did that but they were easy to adjust as the clip rotated. This doesn't. I am not demanding about sound quality, these headphones are really awful.
Summary: Well, it worked great, for all of about 20 seconds... and then the right side stopped working. (Not an exaggeration)! I know these were a fairly cheap pair but I was expecting them to last a couple of months at least.
Summary: I had these earphones just over 1 month now. At first I thought they were great, good strong sound etc. and great for gym/jogging. But after about 4 weeks the right side stopped working. It may be a a loose wire. Ideally I would like to return to amazon, but am outside the 30 day period.
