Just got a 5S and the volume is weak. Disappointing to say the least. Switching to MONO in accessibility helped slightly.Then of course no volume limit or EQ. I also downloaded a couple of these crap volume booster apps. Minor improvements, still it's not as loud as the 4S.
Apparently this is supposed to help. It's a rechargeable headphone amp. £20. http://www.bigmouthstrikesagain.com/archives/5186
If you only play music through the official music app the app "Denon audio" seems like a good solution. However if you use other apps like spotify or YouTube it doesn't help.
None the less I shouldn't have to do this! Apple stuff is ******* expensive. With the amount everyone pays for it you would at least expect it to be of a better standard. It's not even like the gear lasts long. Laptops, phones, headphones, chargers all break so quickly.. Would be nice to know your getting what you pay for. Seems like all wer paying for is the name..
I'd rather have decent audio quality than a ******* finger print reader.
It's a real shame. Hopefully something can & will be done about it..
