This mini version of the Volbox is a tiny and slim inline audio volume adjustor that makes volume control quick and easy. Just pass your audio through. The knob is nice to grip and smooth when turned. You can keep it in a spot that's easy to reach, or mount it somewhere out of sight. The stereo input and output jacks are the common 1/8" (3.5mm) size. No batteries are required. It works great as an inline headphone adjuster. It can be used with aux jacks or as an attenuator too. The Volbox Mini is hand built in Canada with good quality parts to provide many years of service. It has a tough ABS case that's held together with screws. It measures 1 3/8 x 1 3/8 x 5/8 inches thin (35mm x 35mm x 15mm) and weighs 0.6 ounces (17 grams). The knob pokes out 5/8 inches (15mm) and is about 3/8 inch (10mm) in diameter. You can pull off the knob and replace it with a bigger one if you prefer. Note: This will NOT make the volume louder than the music player's maximum level. For that you would need an amplifier. No cables are included. The Volbox includes a brief instruction card and uses minimal packaging to reduce the impact on our planet. Please contact me through at any time if you have questions about using the Volbox in your system and I will be happy to help you. Please remember that the cables are not included. -Clark
