The SMH710 is a light weight version of Pro Intercom's SMH310. The construction, though smaller, is very similar. At 3.88 oz. (0.11kg) it is among the lightest headsets suitable for intercom that is available, and far more comfortable than the most commonly available light weights. Because it has a dynamic microphone it is suitable for all intercom stations, old and new. The microphone arm is a flexible gooseneck and has a swivel mount, permitting a wide range of positioning. The headset comes with a foam microphone pop filter.
The SMH710 is for left side use only. The ear cushions, being smaller, sit on the ear rather than around it. They can be cleaned and can be easily and inexpensively replaced. The headband is adjustable and padded. On the earspeaker side the adjustment involves clicking the fitting up and down. For larger sizes the pad on the far side can be adjusted by removing a small screw and resetting the pad position.
The SMH710 has a minimal number of moving parts. Each of the pivot points has been strengthened. The flexible gooseneck bends rather than breaks. The muff, along with its frame, pops off the ear cup for almost instant cleaning or replacement. Pro Intercom's always-generous repair policy applies to these modestly priced head sets as well.
This headset is compatible with Clear-Com equipment.
