This Fiio E6 Portable Headphone Amplifier drops from $27.99 to $18 at BuyDig. With free shipping also included, this is the best deal we could find for this amp by $7. It's just bigger than a quarter and connects to your headphones and any media player through the audio jack, improving the sound quality and decreasing noise distortions. There is no sales tax (except NJ).
