For only $39, the Fireye Mini will improve the dynamic range and sound quality of any 1/8th" line out, but that's only the beginning. It will drive any pair of headphones for a full 24 hours before the mini-USB battery needs to be charged, and it's packed into a casing so small that the Fireye Mini is more at home on your key-chain than in your backpack.
The all-new Firestone Audio Fireye Mini is one of the smallest headphone amplifiers in the world, and offers improved sound quality across the board with all iPod, iPad, iPhones products, as well as anything else with a 3.5mm headphone output. No matter the device or the headphones, this matchbox-sized amp will give you better bass response and authority, clear and open highs, and improved stereo imaging.
The Fireye Mini could not be easier to use: simply charge via the USB connection to your computer, and then connect to the headphone output of your portable music player to enjoy great sound on the go. Aside from this one extra connection, you can use the controls of your music player just like you normally would. It's available in a choice of five colors: Green, Gray, Purple, Red and White.
Sound and Vision Magazine Fireye Mini Review by Brent Butterworth, December 2011 The Mini’s performance was anything but mini. It reminded me of some of the old tube amps I’ve owned, with the same fat, satisfying sound. The treble is super-smooth, although it’s also a bit on the soft side. The horn-heavy jazz orchestral arrangements on Freddie Hubbard’s Hub-Tones tend to sound a little blarey through many IEMs, but the Mini mellowed them out nicely.
Head-Fi Forum Review by tomscy 2000 April 2011 I can say is that the Fireye Mini feels significantly better as a portable amplifier. There seems to be better bass energy, better high end sparkle, and a noticeably more expansive soundstage --- pretty impressive for something so small. It doesn't seem to extend too far down low, and there's a slightly warmish coloration and very slight reverberation to every note, but because of that, there is a definite airiness that is constantly present, giving better instrumental separation to my music.
