Put it in the back of my 06 Envoy as it didnt come with any power source behind the center console. Will update when it reaches. Just try these on before you buy it. After a couple of hours it looked like I had been walking through tar. But at work I want to other voices blocked as much as possible so I can focus, so I have "hear-through" set to Off. If you?re good with walking in heels, I would absolutely recommend. The build quality doesn?t disappoint. Plenty of bass without muddying the mid-range and crisp clear highs. Using a frequency generator through my phone I was able to hear from about 55Hz to about 11500Hz. BUT IT IS BETTER THEN A DEAD PHONE.
