My Polycom IP331 has an RJ9 port for the headset like the handset not a 2.5mm, but this list that model??? How does that work?

The 2.5 is the typical size, but Radio Shack will have adapters. Go do that, this headset is outstanding. Best of luck. Rossi

If you want to use the headset as described above it will not work for the 2 pin choice. The 1 pin operates both mic and earpiece

...if that model has a headset jack that is the same size as the handset wire connector, it should work. Mine works well on a Cisco IP Phone 7945.

Looking at the handset and at the ans mach base unit, I do not see a port to adapt a headset to this device.

I'm not a speaker person so I honestly cannot answer that part of your question. I only use the speaker when calling in scripts or listening to vm. It only has 1 headset port.

Yes, I've sold hundreds of these headsets and this will work great! Plantronics.com will help coordinate the phone and headset. Go to "Support" and then click "compatibility guide" for an overview. Let me know if you need any additional assistance! Good luck Ritesource

These only work with the Cisco/Polycom conferencing phone. They have a specific connector that only works with that phone model.

It only connects to the phone via RJ11. The AC charger that goes into the outlet plugs into the headset base via 3.5mm.

I can not say for sure as I don't have that model. But I can ask two questions; Does your phone have a seperate headset button? and does your phone block your talking in the earpiece? In other words you hear the other parter speak but when you speak you do not hear yourself? If you say yes to both questions then I believe this would work with your phone. The input for the headset is a standard 4 wire phone jack. I am very pleased with my purchase and use it almost every day.

I think that's what I was using when I had this headset. The headset was okay, but people were always asking me to speak up. Maybe it was because we had 5 or 6 people in a small room all on the phone at the same time. I highly recommend you getting a two ear headset, such as the Plantronics 478 Headset. We quit using the one you're asking about after a few months. I don't know if it will work with the soundpoint IP 335, though. I don't use that phone anymore either. I'm straight VoIP and use the USB Plantronics 478 Headset. I hope this helps.

It only works with expandable Soundstations. Turn your Polycom over and look at the bottom. If it has only one port/jack for the telephone cord, then it's not expandable. If it's expandable, it will have the port/jack for the telephone cord plug-in and will have two additional ports/jacks for the two microphones to plug into.

Well, a 3.5 MM plug is too big, so I'm guessing it takes a headset with a 2.5 MM plug. I don't know if it's mono or stereo. Next time I order from Amazon, I'm adding a Monoprice 107121 2.5mm Mono Plug to 3.5mm Mono Jack Adaptor, Gold Plated and hoping it will work.

Hi Jewel,Yes the 2.5mm works perfectly, if you get a 3mm there is an adapter available on Amazon or Radio Shack but if your phone calls for a 2.5 this headset will work very well. I'm an executive recruiter and wear the thing from 9 am to 4 pm and it's light, comfortable and doesn't break (I'm hard on head sets... really hard believe me on that one.) I would buy again, and probably will before summer, after I drop it on my chair and I sit on it, or jam it in a drawer without looking or one of the office cats chews on the wires. Hope this helps.Mike DesmondCincinnati OH

So far I know, your headset works with only 3.5mm 4-pole jack.. but cannot assure on the selected one. :(

Oops. I read headset in stead of handset. But the answer is the same. I don't know and can't help.

The 214 headset has a 2.5mm pin for use with a portable phone. The Headset Buddy adaptor is what I use with my Plantronics 214c with my cell phone. The Headset Buddy has a 3.5mm pin that fits in virtually all cell phones.
