Unfortunately don't get as much use out of this as I used to, time to move it along to someone who will enjoy it more.
Headstage Arrow 4G, absolutely killer little portable headphone amp. Two lines out for separate headphones, EQ, Gain, and Crossover controls. Holds charge like a champ.
Truly tiny: 3 7/8" x 2 1/8" x 1/4"
Will throw in 6" Cardas 1/8" stereo jumper cable for free.
