    Ferrite Cores (1 PAIR) for 24AWG HDMI® Cable

    Ferrite cores are great enhancements to any electronic signal transmission line. These magnetic materials absorb signal interference, reduce signal errors and improve signal integrity. Unfortunately, factory molded on versions for large gauge cables tend to be disproportionately large and interfere with each other in side by side connections. These extremely effective, yet very compact snap-on versions accomplish the same task without getting in the way.
    Note:  Will not fit 24AWG cables with net jacket, or 22AWG/28AWG.

    Pros: compact, good price, effective

    Cons: none

    These are more compact than the ferrite cores that come pre-attached to some HDMI cables, so you can have multiple cables plugged into a home theater receiver without the cores pushing against each other. They also do what they're supposed to do very well no signal interference. Good product!

    Mixed feelings about this item

    Cons: Too small opening to fit easily on PID 3658 - 24AWG silver-plated HDMI cable.

    I had to squeeze extremely hard to fit onto 24AWG cable. Pliers were required and some of the ferrite cores broke when being squeezed closed.

    This was not expected as both ferrite and cable were specified 24AWG.

    Tight fit around some cables

    Cons: Somewhat tight fit over 22g HDMI cable. Once the cores are closed, HDMI cable seems undamaged and works properly.

    I was concerned about how tight the fit is over the 22g HDMI cables. I broke a couple of the cores trying to squeeze the cores closed over the cable using pliers. I did learn to do it on several cables, though. Better to squeeze hard without pliers.

    Pros: The ferrite cores seem well constructed. They stay attached properly and are exactly what I expected. Two cores (1 pair) were included in the package as expected

    I purchased these to add to a cheap pair of speakers to eliminate interference from nearby cell phones. Added the ferrite made _no_ difference. Although the ferrite cores are perfect in themselves the Internet's advice that ferrite cores would solve my problem seems to have been incorrect.
