  1. Lael R.

    I love having this item because it means I would never have to buy batteries for my amplifier. Awesome.

  2. Weeezie

    Nice headset, fits nicely over my ear. Easier than the handset.

    Now if I can figure out how to plug everything in properly since I can hear the individual on the other end, but they can’t hear me. Had to go back to using the handset, which I loathe.

  3. Margie

    I purchased this adapter when I ordered my M22 amplifier. I was told I didn’t need the adapter, because the batteries in the M22 last a long time, but I figured the price was so low, I went ahead and ordered it. One less thing to remember. Thank you Headset Direct!
