But how do the M8 and S5 compare when hooked to a car audio system via A/V jacks? I'm leaning towards buying the M8 b/c I currently have the HTC One S w/ Beats and love the sound in the car. I plugged my Samsung pro 8.4 tablet into the car system last night and playing the same song on the One S and the tablet is night and day. Much better via the One S and I'm going to assume the S5 has the same set up as the new pro tablets. Any thoughts, I like both phones, but both have pro's and con's in my book! But the boomsound and how it sounds in the car will decide for me. Just wondering if any one else is in the same situation.
