Poly StarSet H31CD Headset Review: Is This Wired Single-Ear Headset Right for Your Desk Phone?

A practical look at the wired, over-the-ear Poly StarSet H31CD headset for office and call-center phone work. We dig into the single-ear design, flexible boom mic, and the trade-offs of a QD-based headset.

Last updated Aug 15, 2026

Choosing a headset for an office phone often comes down to whether you need one ear open to the room or both ears in the call. The HP Plantronics Poly Over-the-Ear StarSet H31CD Headset 8K780AA#AC3 is clearly in the first camp: a wired, over-the-ear headset with a flexible boom microphone, priced at USD 214.99.

Quick verdict

This is a durable headset for someone who spends long shifts on a desk phone and wants a lightweight feel. Its design is straightforward: a flexible mic and a comfortable hook over the ear. The TAA-compliant label may be useful if you're buying for a workplace that requires it.

Who it suits

The StarSet H31CD fits into a traditional office phone environment. It works with Poly/Plantronics QD adapters and compatible desk phones, so it's aimed at people who already have that infrastructure. If you work at a call center or a busy front desk, and you need to hear a phone call while still being present for people around you, this headset is designed for that kind of multitasking.

What stands out

The flexible boom mic is the most adaptable part of the headset. You can bend it into the position that works best for your voice, and it doesn't feel like a big obstruction. The Quick Disconnect interface is another notable feature: it lets you step away from the desk without pulling off the headset, provided your phone system has the matching QD connector. The hook is lightweight and low-profile, which supports all-day wear.

Meaningful trade-offs

The main trade-off is the monaural audio. You hear the call in only one ear, which is great for staying aware of your surroundings but not ideal for focused, immersive listening. The wired connection also keeps you tethered to your desk, and the over-the-ear hook isn't a full headband, so some people may prefer a different fit.

Product note

One reason to choose the StarSet H31CD is its TAA-compliant status, which can be a deciding factor for certain buyers. A limitation to keep in mind is that it depends on a compatible Quick Disconnect adapter or phone system to deliver its main convenience. The listed price is USD 214.99.

Bottom line

For desk phone users who need a durable headset with a practical design, the Poly StarSet H31CD is a worthy candidate. Just go in knowing it's a mono headset and not a dual-ear model. If that matches your workday, it's a solid choice.
