Plantronics SHS1890-15 Push-to-Talk Headset Amplifier

Plantronics SHS1890-15 – Push‑to‑Talk Headset Amplifier for Two‑Way Radios

The Plantronics SHS1890-15 is a rugged, portable push‑to‑talk (PTT) amplifier designed to connect a standard Plantronics headset to a two‑way radio or other push‑to‑talk communication device. Whether you’re in security, event production, construction, or public safety, this amplifier provides clear, amplified audio and a tactile PTT button for instant voice transmission. It bridges the gap between high‑quality headsets and professional radio systems, improving comfort and clarity during long shifts. The amplifier is ideally suited for use with Plantronics headsets that feature a Quick Disconnect (QD) connector, and it includes a built‑in belt clip for easy carrying.

How It Works

The SHS1890-15 connects between your Plantronics QD headset (or compatible headset) and your two‑way radio’s microphone/speaker jack. The amplifier boosts incoming audio for better listenability in noisy environments and provides a large, easy‑to‑locate PTT button on the inline module. When you press the PTT button, the amplifier sends your microphone signal to the radio; release it to listen. The unit also includes a volume control dial, so you can adjust the speaker level without touching the radio. It is powered by a single AA battery (included), making it portable and ready for field use. For a complete hands‑free communication setup, pair this amplifier with a durable corded headset from FindHeadsets – we offer a range of Plantronics and compatible models designed for rugged environments.

Compatibility & Design

The Plantronics SHS1890-15 is compatible with most Plantronics headsets that use a standard Quick Disconnect (QD) connector, including the StarSet, SupraPlus, and EncorePro series. It also works with many two‑way radios that have a 2.5mm or 3.5mm jack (check your radio’s connector type; adapters may be required). The amplifier module features a heavy‑duty belt clip, a coiled cord to the radio (approx. 1.5m), and a straight cord to the headset (approx. 1.2m). The PTT button is large, tactile, and positioned for glove‑friendly operation. The unit incorporates a gain control for mic sensitivity and a volume dial for speaker output. The amplifier is powered by one AA battery (alkaline or rechargeable) with a typical battery life of 100+ hours. The housing is impact‑resistant and rated for indoor/outdoor use.

Why Choose This Product

Using a standard headset with a two‑way radio often results in poor audio quality and uncomfortable earpieces. The SHS1890-15 solves this by letting you use your comfortable, high‑quality Plantronics headset with the radio. The amplifier boosts incoming audio so you can hear clearly in noisy environments, and the inline PTT button eliminates fumbling for the radio’s tiny button. The rugged construction withstands drops, dust, and everyday field use. For security teams, event staff, or warehouse crews, this device dramatically improves communication efficiency and reduces fatigue. It’s also a great spare to keep in your kit.
