Clear-Com Earphone Adapter (Model #1620) Quantity: 1 If you need multiple units, please send us a message and we will accommodate your request. This is our original design, and we use non-degrading solder for all connections. This product is for concert, TV, and theater professionals. Please do not purchase if you are not in these fields. This "earphone adapter" allows you to listen to audio without a headset by plugging your own mini-stereo earphones into a Clear-Com or compatible device. Even in extremely loud environments, simply connecting your earphones to this product will not only block out unwanted noise but also provide significantly clearer audio compared to the original headset. Returns due to customer circumstances are not accepted. However, if the product is unopened, we will accept returns if you cover the return shipping costs. Thank you for your understanding.
