iPhone 4s audio
All these reports of the new 4S not performing audio output as well as previous models is very disappointing. I was considering upgrading my iPhone 4 to a 4S but if the audio is not as good I will wait. As an audiophile type I was rather frustrated by the lack of a fully manual EQ within the music player on the iPhone / iOS . I did a bit of searching and I found the App EQ-U . I listen to my music with a pair of ACS T2 in ears and now play music through the iphone via the EQ-U app. I found a real improvement in audio output quality and can fully tweak the EQ to suit my in ears. If your having a problem with the audio on the 4S maybe try downloading the EQ-U app and see if it helps. I Hope it does !
