I'm sorry, but I don't think this is the case, at least not for me. I actually own a pair of Bluetooth earphones, which I use at the gym. They do well, I don't have to worry about the cable or accidentally hitting the phone in my pocket when picking up weights. They have a reliable connection, sound is decent.

But I have hundreds of dollars invested in good-quality wired headphones, plus wired earbuds, and I want to be able to use those with my phone without needing to re-spend that money. Plus, regardless of quality of the product, I'm occasionally a forgetful human. I've actually run out of juice mid-workout with my wireless set. Instead of not having music for the rest of my workout (I like music!), I simply walked over to my bag, pulled out my wired earbuds, and finished up.

Not having the ability to do that is a deal-breaker for me on a phone, and it's not something that can be fixed by improving the Bluetooth tech. While this is obviously anecdotal, I don't imagine I'm the only person who feels this way.
