Up for auction is an audio engine DAC3 headphone amplifier. This unit will work with Apple products and Samsung product products. And possibly many others. It plugs into your phone data connection port and amplify the headphone output significantly over what the phone itself is capable of doing. Low and high range sounds are significantly improved and you do not lose microphone and control functions. This is a very nice unit that I purchased from Crutchfield about six months ago. I just happened to have found one that I like more. It is shipped as shown with the two cables one for lightning for Apple and one usb c.  The unit is quite powerful and greatly enhances your listening experience. Unit will ship USPS priority mail.
