ambient noise.

OVERVIEW

These monaural headsets work with mobile phones that

accept a 2.5-mm plug. For mobile phones without built-in 
2.5-mm ports, optional adapters are available.

Each of these lightweight, compact headsets provides

superior sound quality.

Six models are available. They differ according to their

wearing styles and additional features.

Wear the 

Pro-Fit Mobile Headset (HS400A)

in one of three

ways. Choose a flexible earhook, four sizes of earloops, or a
monaural click-stop headband with an ear pad. It also
includes a maintenance kit (an ear pad, mouthpiece cover,
and cleaner).

Position the 

Genie Mobile Headset (HS401A)

over the

head. A click-stop headband assures a secure fit. The headset
features a flexible microphone boom that you can adjust
when you want to eat or drink. Like the Pro-Fit, the Genie
Headset includes a maintenance kit (an ear pad, a mouthpiece
cover, and cleaner).

Use the 

2-in-1 Mobile Headset (HS402A)

in one of two

ways: over the ear or over the head. Switching between the
two wearing styles is quick and easy. The 2-in-1 Mobile
Headset cuts down on static via radio frequency (RF) shielding.
Like the Genie, the 2-in-1 Mobile has a flexible microphone
boom. It also has an adjustable earpiece and swivel-mount
receiver for added convenience. It includes a maintenance kit
(an ear pad, mouthpiece cover, and cleaner).

If you’re looking for a super-lightweight headset, choose

one of the Eloquent Headsets. Each weighs less than an
ounce. Like the 2-in-1, you can wear the 

Eloquent Convertible

Headset (HS403A)

either over the ear or over the head via a

headband.

The 

Eloquent Compact Headset (HS404A)

is small enough

to fit in a purse or pocket. You can wear it over the ear.

The 

Over-the-Ear Mobile/Cellular Headset for Nokia

8260/8290 (HS405A)

offers a secure and comfortable fit. An

adjustable microphone has sleeves for all-season protection.

Black Box also carries adapters for mobile phones with

connectors other than 2.5 mm. We have adapters for Nokia
and Ericsson

®

phones. Call Technical Support for details.
