Convertible Wearing Styles for Individual Comfort
The H31CD gives you genuine flexibility in how you wear your headset throughout the workday. The over-the-head configuration distributes weight across your crown, ideal for team members with longer hair or those who prefer traditional headband stability. The over-the-ear option hooks securely without disturbing hairstyles, a feature our field service and customer-facing teams particularly appreciate.
Converting between styles takes about ten seconds—no screwdriver, no parts to lose. Simply detach the headband assembly and attach the ear loop, or reverse the process when your preference changes. We’ve tested both configurations through thousands of wearing cycles to ensure the attachment points maintain secure contact without loosening over time. The same wired headset lineup used in call centers worldwide features similar adaptable designs, reflecting our understanding that one-size-fits-all rarely fits anyone comfortably.
Noise-Canceling Microphone Engineering
Background noise on customer calls creates frustration on both ends of the conversation. Our noise-canceling microphone on the H31CD uses directional pickup patterns to capture your voice while rejecting sounds originating more than a few inches away. This means keyboard clicks, nearby conversations, and ambient office hum stay out of your caller’s ear.
The microphone boom bends and holds position without drifting during calls. Position it about a finger’s width from the corner of your mouth for optimal pickup—close enough to capture clear speech, far enough to avoid breath pops. The foam windscreen adds another layer of protection against plosive sounds. We recommend replacing the windscreen every six months in high-use environments to maintain consistent audio quality.
Quick-Disconnect Functionality
The inline quick-disconnect (QD) adapter sits between your headset and your desk phone or amplifier, creating a breakpoint that lets you walk away without unplugging cables or lifting the headset over your head. When a colleague stops by your desk or you need to grab documents from the printer, simply pull the QD connection and go—your headset stays comfortably in place.
Reconnecting is equally simple: align the connector and push until it clicks. The QD interface works with all Plantronics amplifiers and compatible phone systems, giving you flexibility to upgrade your desk setup without replacing headsets. Many of our customers standardize on QD-enabled headsets across their entire team, allowing quick headset swaps during shift changes or equipment troubleshooting.

Common Questions About the H31CD StarSet Headset
The H31CD requires a Plantronics amplifier or direct-connect cable to interface with your phone system. The specific amplifier model depends on your desk phone manufacturer and model number. Our M10, M12, or M22 amplifiers cover most standard office phones, while specialized models like the MX10 handle multi-line systems. Contact our compatibility support team with your phone model for a definitive recommendation.
Yes, when paired with a Plantronics USB adapter like the DA series. The adapter converts the headset’s analog connection to USB and provides digital audio processing for applications like Skype for Business, Zoom, or RingCentral. The quick-disconnect feature works the same way whether you’re connected to a desk phone amplifier or a USB adapter.
Pull the headband assembly straight up and away from the speaker housing to detach it. Line up the ear loop attachment point with the same socket and press firmly until it clicks into place. The process reverses when you want to switch back. Both the headband and ear loop ship in the package, so you have both options from day one.
We back the H31CD with a two-year limited warranty covering manufacturing defects in materials and workmanship. This includes the headset body, microphone boom, cable assembly, and wearing accessories. Normal wear items like ear cushions and windscreens are excluded but available as low-cost replacement parts. Register your headset within thirty days of purchase for streamlined warranty service.
In typical office use, plan to replace the ear cushion every twelve to eighteen months and the microphone windscreen every six months. High-volume contact center environments may require more frequent replacement—watch for compressed foam, visible tears, or audio quality degradation as replacement indicators. Both parts are inexpensive and ship quickly from our parts department.
The noise-canceling microphone significantly reduces ambient office sounds like keyboard typing, nearby conversations, and HVAC hum. The microphone uses directional pickup to focus on your voice while rejecting sounds originating farther than a few inches away. Position the boom about a finger width from the corner of your mouth for optimal noise rejection. Extremely loud or close sounds may still be partially audible to your caller.
The H31CD is hearing aid compatible when used with appropriate amplifiers. Look for amplifiers marked HAC (Hearing Aid Compatible) or those meeting TIA-1083 standards. Our M12 and MX10 amplifiers both offer hearing aid compatibility modes. Consult with your audiologist about optimal volume settings and wearing configurations for your specific hearing aid model.
