When you listen to music through a crummy pair of headphones, it’s hard to really get into what you’re listening to if exterior sounds keep creeping in. Sometimes, even when you have a good pair, you just can’t drown out the outside noises. The volume is just never loud enough, and there’s nothing you can do about it.

That is, unless you have something like the Fiio E1 Headphone Amplifier for iPhone. It will work with all generations of iPods and iPhones, which is good news for those of you that still have a gen 1 and don’t intend on upgrading anytime soon. This was manufactured by Texas Instruments, and uses the signal from the line out to make things easier for plug and play. The playback control is conveniently located on the line, so you won’t even have to have your device out to change out songs or volume. It will only cost $20, and comes with a clip so you can attach it onto something convenient like your jacket or purse.
