Pros: Sound Qualiy,Fully Customizable Sound, Portability.
Cons: Wating Time..
Headstage Arrow 12HE is an excellent product, offers an unmatched sound quality at a very low price. It is an amplifier that can shape your sound depending on our phones. In terms of portability is one of the best, only beaten by iBasso T-series. I use the Arrow with a TF10, and I tell you it is a great combination. Apart from the waiting time (from May 16 till now) I am totally satisfied with your purchase, 100% recommended!
