I have almost never used the headphone jack on my S7 and zero now that I picked up some bluetooth headphones.
Same. Almost never used the headphone jack on my Galaxy S6.
I used to always use a dac/amp for music but I almost never listen to music on-the-go anymore, when I do, I accept its inferior sound quality in comparison to my static system and non-mobile headphones.
I had this epiphany listening to some incredible-sounding music while kicked back with my eyes closed. The experience was so profound I thought to myself... why do I even bother trying to get this level of sound while out on walks using a portable DAC/amp, or sitting at my desk at work. You can't appreciate the sound quality if you're not focused on it.
So, I'm fine with wireless headphones while out walking.
