I bought these headphones for the occasional jog and so far they have worked perfectly. I have fairly small ears which these headphones snuggly shaped around so if you have large ears there may be a chance this product will be uncomfortable. Some other reviewers reported looseness but so far even when running they have stayed tightly fitted. The audio quality is pretty average, at best it's similar to the iPod bundled headphones so don't be expecting too much on that end.
Pros:
- Brilliant for jogging
- Comfortable design
Cons:
- Average sound quality
- May fall off for some
Conclusion: Buy these headphones if you intend on going running with them, if not, these headphones are pretty average in sound quality so you may want to look elsewhere. Recommended.
