Query: Sturdy, but otherwise not that great

I've been using these headphones for a few months at the gym.Pros:- They are sturdy and well-made.- Sweat does not seem to bother them.Cons:- They don't fit well in my ears. I don't have a problem with most earbuds, so this is unusual. The buds are large and the earpieces don't give much support on me - they fall out easily.- The earpieces are not adjustable.- The sound is just not good when they're not in your ear canal. No bass at all, and the other frequencies are muddy.Summary:I would not recommend these for those looking for good sound. I would also not recommend these for people doing vigorous activity where they're likely to fall out.
