I’ve mentioned a few times that the iPhone 5 is much quieter than the iPhone 4/4S on some headphones, such as my Atomic Floyd Superdarts, and I suggested using the Denon Audio app to boost the volume. It’s better, but it isn’t perfect: if you’re trying to address a lack of low-end thump, as I am, it runs out of puff long before you’re happy.
There’s a more elegant solution, but it’ll cost you Â£20: the FIIO E6 headphone amp. It’s good for ten hours between charges, it’s the size of a large postage stamp and it’s bloody brilliant.
If you’ve moved to the iPhone 5 and feel your headphones now lack oomph, this’ll solve your problems. I’m really impressed by it.
