The Galaxy Audio HS13-UBK unidirectional headset is a standard choice for the EDX Headset System. Its comfy wrap-around design covers both ears, keeping the mic firmly in place. Key features include unidirectional sound, ear-hooking design, standard for EDX, and a TRS 3.5mm connector.

Using this headset is easy. Just place it over your ears with the wrap - around design. The unidirectional feature means it works best when pointed towards the sound source. When connecting, plug the TRS 3.5mm connector into your device. For maintenance, keep it in a dry place. Avoid pulling on the cable too hard. If it gets dirty, gently wipe it with a soft, dry cloth. Don't use harsh chemicals. Also, make sure to store it properly when not in use to prevent any damage.
