It was once a search for the best sounding earphones for my iPhones, for me that is the Etymotic hf3. Now it being held hostage by batteries. Used to be cable failures now it is batteries failing to charge. I love the necklace design for earphones. What I would love to see is one that you could use AAA batteries. Except for the connected Klipsch Neckless all of the others are draped over my desk lamps with charging cables plugged in. Here is what Apple has done to me.
