The PRYME FUN-2 features a lightweight microphone designed to be worn on the user's lapel or collar. It has a handy Push-to-Talk (PTT) switch on the side. A PTT locking slide switch on the back allows VOX operation (if radio has this feature). For listening, this unit features an in-line earphone with soft ear-hook that fits comfortably and holds itself in place during strenuous activities. The earphone can be used on either the left or right ear depending on your preference. The FUN-2 is great for business, such as warehouse and security operations, as well as skiing, hiking, off-roading, paintballing and many other activities.
