Simple use of numbering to tell you everything
- Power inlet is beside source input, on the left
- audio out on the right, with 2 LED: blue for power display, red for charge
- back is shirt clip
Cable that comes along is one right angle 3.5mm to straight 3.5mm jack. Charger is usb to DC inlet
Since it's a passive amp, so I am expecting it to not draw it's own characteristics to sound, but merely amplifying what you give them. So, this is a confusing part, does it have it's own colouring or just a impedance lift up? I have no idea
Cant say much about it, but for people who thinks they need more power, say for 250 ohm headphone maybe, can sure try this unit. It's not expensive at all, really. Maybe a pack of cigarette or 2.
