I would have liked to of pushed the shafts of the bits in farther but they are a bit tight. I bought these to replace my Keen Newports after years of faithful service. Not a good choice for serious hiking but great for Summer travel and walking around the mall and beach. But it doesnt stop there. I wasn?t expecting top of the line and was completely disappointed with what I got, just wish they would have lasted longer than a few months. Unfortunately, same problem. And guess what? It is awesome for gaming too! Anybody know whats going on? Speaker is fine as it works perfectly with my cell phone and laptop. These headphones work really great for this purpose, too, because I can really crank the volume up and get great sound, whereas other headphones I?ve owned haven?t really been able to do that job so well. I don?t know what?s going on.
