    Lightweight & flexible aux to USB-C cable

    Connects your phone/tablet to a receiver or as in my case, a mini amplifier that powers a couple of bookshelf speakers for my garage radio/stereo. Sound quality is superior and less of a hassle than via Bluetooth or other means. Cord is a little on the thin side, but with my setup, I actually prefer the lighter weight and less rigidity of say a braided or jacketed variety.

  • Can this cable be used to connect my AirPods Max (usb-c) to my MacBook Pro headphone jack?

    The Insignia™ 3’ USB-C to 3.5 mm Cable is designed to transmit audio from a USB-C device to a 3.5 mm audio input. However, it does not support audio transmission in the reverse direction (from 3.5 mm to USB-C). Therefore, this cable would not work for connecting your AirPods Max (USB-C) to your MacBook Pro headphone jack. Patricia | Insignia Support

  • I am wondering will this work for my projector (3.5mm) connected to speakers (USB-C) and play sounds from the projector out of the speakers?

    Hello Andrew! The Insignia™ 3’ USB-C to 3.5 mm Cable (NS-MCX321K) is designed to transmit audio from a USB-C device to a 3.5 mm audio input. This means it works well for connecting USB-C enabled devices to 3.5 mm audio jacks, such as headphones or speakers. However, in your case, you want to connect a projector with a 3.5 mm output to speakers with a USB-C input. Unfortunately, this cable won’t work for that setup because it doesn’t support audio transmission in the reverse direction (from 3.5 mm to USB-C).
