iPhone7 Without Headphone Jack

It's reported that iPhone 7 may not have the 3.5mm headphone jack to make it simpler and thinner.And the jack to headphones will be the lighting jack.It causes many people feel unsatisfied because they can't listen to musics while charging.But as I think,Apple may do a good thing.If people can't put two plugs into one jack in the same time.There is an other way for headphone,the Bluetooth headphone.Someone may say Bluetooth headphones cost to much power and the tone quality of Bluetooth is worse than wired headphones.But in fact,the Bluetooth has become into an energy saving technology so it won't cost to much power and though its tone quality isn't as good as wired headphones',the tone quality can satisfies most of the customers.And wireless headphones don't have the wire tingling trouble.Wireless is the future.If iPhone 7 drops the headphone jack.It will be a big progress.
