The DB12 is powered by THX AAA technology to deliver studio-quality analog (gloriously not digital) amplification to any wired headphones. The DB12 is compatible with 3.5mm equipped audio devices with extremely simple plug and play use. This ensures that you can carry a phone or player in your pocket or bag and still access the inline controls without taking the device out.

The cable’s length from the source to the DB12 is a very long 24”, and the distance from the body to the headphone adapter is 2”. The high conductive silver coiled cables that extend from both sides of the unit are wrapped in cloth, flexible yet sturdy, and non-microphonic. The DB12 as a physical device is noiseless and generates a slight warmth in use which I never find bothersome. The aluminum dissipates heat and is remarkably resistant to fingerprinting and smudging (refrigerators claiming to do the same could learn a lesson or two from the DB12 materials experts). One side of the DB12 has a USB-C port to charge the device while the small light indicates battery status. Once there, it will not move on its own or with an accidental swipe. Depending on your fingers, this slider can be challenging to shift into place and not overshoot the position you are going for. The upside and downside of the small 3-position plastic slider switch are that it’s stiff and requires effort and precision pressure. Inline controls are primarily designed for mobile devices and vary on PC, Gaming Consoles & Music Players.
