Avaya 1400, 2400, 4600, 5600, 9400, and 9500 series phones (1408, 1416, 2410, 2420, 4606–4630SW, 5410–5625, 9404–9508, and the 4400+ Partner-style models) all take headsets the same two ways: corded through the phone's headset jack, or wireless with an EHS cable for remote answering. Here's how to choose, and the current certified picks for both.

Corded or wireless: how to decide
Corded headsets are the cheaper option, generally $120–$185, and plug directly into the phone's headset jack — press the headset button and you're connected. Wireless headsets start around $260 and let you answer calls away from your desk, which most people find is worth the extra cost once they've tried it. If your office is noisy, choose a binaural (both-ear) headset for better passive isolation, whichever connection type you pick.

Most people who go wireless want the ability to answer calls away from the desk phone — that requires an EHS cable to complete the setup.
Myth
The Plantronics Savi 8220 is still the top wireless pick for these Avaya phones.Reality
It's discontinued. The current Poly Savi 8400 series replaces it: the 8410 (mono), 8420 (stereo with active noise cancellation and hearing-aid compatibility), and 8445 (convertible with a hot-swappable spare battery for unlimited talk time). All three connect to a desk phone, computer, and Bluetooth mobile device simultaneously — the same tri-connectivity the 8220 offered, with a current chipset and better encryption.Poly CS540 + Avaya EHS bundle

What headset works with an Avaya 1400, 2400, 4600, 5600, 9400, or 9500 series phone?
Corded headsets like the Jabra Biz 1500, Biz 2300, or Poly HW540/HW710 connect directly through the phone's headset jack. Wireless headsets like the Poly CS540 or Savi 8400 series need an Avaya-certified EHS cable bundle to enable remote answering.

The current Poly Savi 8400 series replaces it: the 8410 (mono), 8420 (stereo with active noise cancellation and hearing-aid compatibility), and 8445 (convertible with a hot-swappable battery).

Should I choose corded or wireless for an Avaya desk phone?
Corded is cheaper (typically $120–$185) and simpler for a fixed desk. Wireless (from about $260) lets you answer calls away from your desk, which most people find worth the extra cost. If you go wireless, you'll need an EHS cable bundle for remote answering.
Is there a hearing-aid-compatible wireless headset for Avaya phones?
Yes. The Poly Savi 8420 is hearing-aid (telecoil) compatible while also offering active noise cancellation and tri-connectivity to a desk phone, computer, and mobile device — a strong option for anyone who wears hearing aids in an office environment.
Whether you go corded for simplicity or wireless for the freedom to step away from your desk, the picks above are current, certified options for your exact Avaya phone family.
