    I have a Plantronics .Audio 340. It was purchased for my PC. Once I plug it in, I can hear other players but they cannot hear me. Any suggestions?

  2. July 17th, 2009 at 10:46 | #2

    If you have the two plugs connected to your computer (3.5mm mic & speaker plug) and you can hear just fine but no one can hear you, it could be a couple of things. I would first check and make sure that something didn’t change the audio mic settings through the control panel on your pc. Sometimes a window’s update or antivirus programs change settings without us knowing… Other than that, it could be that the microphone has just gone out or something is wrong with the mic cable / plug. If this is the case, then it’s just time for a new headset. But check your pc settings and unplug & re-plug the cables first.

    Help- Shoretel/wireless headset question. We have Shortel phones and are using Plantronics headsets. Is there a way to answer muliple lines on your phone using a wireless headset without having to press a button on the phone? We have clerks that need to be able to answer an incoming call on phone or button box when they are away from their desk. At this time, they can only answer the first line on the phone.

    Hi Charlie, thanks for your inquiry with us.
    Most phones are programmed to roll over to the next available line, for example if someone is on line one and you need to make a call, when you pick up your handset you should then be on line two. If your phone is programmed this way like normal, then your headset would work the same way. However if you are refering to being able to answer a specific line, for example someone intercoms you and says “call holding line 4”, the headsets are just not capable of doing that. Just remember that a headset only takes the place of your handset, and it relies on your phones programming just the same. Thanks for your question.

    Help! I am looking for a USB headset to use in our new call center that will be using Avaya. We are only using the soft phones. I would like a headset with yjack/training capabilities. How can I make this happen?

    Can you please tell me what bottom end cable I need to use with my Polycom SE-225 speakerphone? I want to be able to use headsets we have in stock but can’t find the right 2.5mm adapter?

  9. August 10th, 2009 at 09:07 | #9

    A: You can use any “H-series” headset with the Plantronics “Y-Training Cord”
    (model 27019-03) along with a DA45 USB adapter to connect two headsets to a computer for training.


  10. August 10th, 2009 at 09:16 | #10

    A: The Polycom SSE-225 should just have a standard 2.5mm headset jack, you can use any Plantronics “H-series” headsets along with the 2.5mm adapter cable (model 43038-01).

    How can I use a Plantronics headset and amplifier with an Avaya phone wothout having to pick up the handset for every call?

  12. September 4th, 2009 at 08:15 | #12

    Derek – You can use the CS55H wireless unit without lifting the handset. As for corded headsets, the M12 or M22 amplifier will require lifting the handset. Plantronics made a model called the SP-02H which plugged directly into the AUX port allowing you not to lift the handset each time. Unfortunately, the unit was discontinued early 2009, but maybe searching online, you could find a used one.

    I need a headset for work that will do the following –

    1) Plug into a Cisco VOIP phone (the standard one you see everywhere)
    2) Greatly amplify volume (so for example, if the call is very hard to hear even with phone’s volume blasting, headset would further amplify sound)
    3) Has a mute button on board the headset
    4) Cordless would rock but could live without it.

    Any suggestions?

    Hi! Panasonic KX-TG9391T base unit 2-line. What headsets available that can plug into it? It does NOT have a headset plug built-in, but something must exist that can plug into the handset plug. Right? Maybe?

    whats so great about voice tube headsets?

  16. September 14th, 2009 at 09:05 | #16

    In a quiet environment, a voice tube headset will give you your most crisp and clear outgoing microphone quality (What you callers hear). A noise-canceling microphone can soften your voice slightly in a quiet environment.

  17. September 14th, 2009 at 09:11 | #17

    The Plantronics CS55 wireless with the HL10 handset lifter would be Cisco compatible, give you great volume range control and have a mute button on the headset. Click here to view:

    isn’s there noise cancelling tips for voice tube?
    are they functional?

  19. September 23rd, 2009 at 10:23 | #19

    Noise canceling tips for voice tubes are called background noise suppressors (BNS). They don’t electronically filter out background noise like a true noise canceling microphone. They’re trying to capture more of your voice and directing it down the voice tube towards the microphone. Any background noise that’s also present and will still be heard. A noise canceling microphone electronically targets your voice and differentiates it from background noise, thus making your voice more dominate.

    Having trouble identifying a headset to work with a home analog service and a new Dect 6.0 phone (uniden 2188). Cordless handsets do not have jacks and I planned to run it thru the corded base handset. My older M-12 plantronics amplifier and headset do not seem compatiable. What will work together with Qwest home service, Dect 6.0 and provided amplification for the headset? THANKS!

  21. January 22nd, 2010 at 12:46 | #21

    You have a couple of options. First you can replace your existing M12 with a Plantronics T10H and use your current headset. Second would be to use a wireless commercial grade product called the Plantations CS-55H. The third option is the Plantronics CT14 make for home use.

    We have the Plantronics CS55 headsets and were wondering if there is a part that allows a person to use both the handset and the headset with the push of a button? We’d like to be able to go back and forth between the headset and handset. Thanks for your help!

    Good Afternoon,

    I would like to know if it is possible to use any type of wireless headset to switch between analogue (i.e., radio — Maestro), digital (i.e., Nortel 3904) and VOIP (i.e., Nortel i2004) radio/phone systems. I am looking using the Savi Office from Plantronics as a possible solution but I would like to know if there are other products out there that would meet my requirements.

    I ask because our Fire/Rescue dispatch is looking to implement wireless headsets to allow the dispatchers hands-free ability when answering an emergency call(s).

    Is it possible to use the Plantronics CS351N headset with a Panasonic
    KS-TG9381 digital cordless phone? I want to use it with the base unit of the phone but there is no handset or headset port to plug the CS351N into. Any suggestions?

  28. kim
    August 28th, 2010 at 17:06 | #28

    Correction – actually, the phone model is KX-TG9381

  29. August 29th, 2010 at 10:05 | #29

    Any of the CS wireless headsets require a desk phone with a handset to plug into. Your simplest option is to purchase an inexpensive desk phone and use the CS wireless headset with it and use your Panasonic cordless phone as a separate phone.

    i am interested to buy a headset for an Avaya 4610SW IP phone.

    Do you have any recomendation please?

  31. September 9th, 2010 at 11:32 | #31

    We have several headset options that are compatible with the Avaya 4610SW IP phone, you did not specify what type of wearing style would be preferred or if you were looking for corded or wireless, so here are both options.

    As far as corded, you can use any of the “H-series” headsets and you would need the HIC cable to connect the headset to the telephone. The HW251 headset goes over the head and covers one ear, or you could go with the H141 headset which gives you the option to wear it over the head or over the ear, it includes a headband and an earloop (if it will be used in a loud area, you would want to get the noise canceling models – HW251N, H141N). Just remember that whichever corded headset you choose, you will also need the HIC cord (model 49323-44).

    As far as wireless headsets, we have the Plantronics Savi WO100 and WO200 on sale right now which is the best deal. The WO100 is convertible which includes the headband and an earloop, so it can be worn either way. The WO200 goes over the ear and it has an earbud that goes in the ear. The Savi promotion that we have going on right now ($250 each, regular price is $358) includes the HL10 Handset Lifter for remote one touch answering, and is while supplies last.

  32. September 9th, 2010 at 12:15 | #32

    Typically that integration is done within the dispatch console itself, and you would then use a 6-wire push to talk dispatch console amplifier such as the SHS1890-15 with any of the Plantronics H-series headsets to toggle between your phone calls and the dispatch radio. Some dispatch consoles even have a switch that lets you choose between the regular 4-wire and the 6-wire push to talk configuration. You will want to consult with either your IT person or the company that installed your dispatch consoles on how to integrate the two.

    I have an an Offfice Savi WO100 that I use with a Shoretel 230. I have it plugged in to the extra phone port made for the headset and use it by answering the phone on my screen, how can I configure the system to answer using the on/off button on the ear piece? Everything else works fine but would like to use on fucntion and not two.

  34. November 16th, 2010 at 10:34 | #34

    Usually you can answer a call just by pressing the button on the headset, you may need to configure the “Automatic Off-Hook Preference feature” in the telephone menu. Once you configure the telephone “Auto Off Hook” for the headset (go through options, auto off hook, headset), hopefully this will fix the situation. Please consult your user guide or phone person if you are not sure how to configure.

    Is there a T-Adaptor or Y-Splitter that is compatible with the Plantronics CS351N Wireless Headset?

  36. July 19th, 2011 at 14:11 | #36

    Our Wireless Training Adapter will let you train on any of the CS-series of wireless headsets.

    I have a a Plantronics HW261N headset and would like to know if I can use it on the T10? When I tried it I could not make a call out and got a funny noise, I was told I could but now I am not sure if I have to do something to the phone or not.

    help! my plantronics hw261n wont work with cisco ip phone 7940

  39. January 28th, 2012 at 11:20 | #39

    You will also need the 26716-01 cord to make the HW261N headsets work on the Cisco 7940 phone.

    I have a Plantronics HW261N (D261N Stereo/DA-M/A – PN 80762-42)
    Is there a RJ9-QD adaptor that would allow me to plug this headset on my Shoretel 265 IP phone ?
    Thank you.

  42. June 4th, 2012 at 08:42 | #42

    The Shortel IP265 phone has a dedicated headset jack, this will allow you to plug the Plantronics A10 (66268-03) cable directly into the phone. On the other end of the A10 cable there is a QD adapter for the Plantronics HW261N headset to plug into.

    How do I replace the battery in my Plantronics Discovery 925

  44. July 3rd, 2012 at 10:21 | #44

    If you’re having battery issues with the 925, you will need to replace the entire headset. To make it so light-weight and small, Plantronics had to fully enclose the battery in he casing which doesn’t allow for battery replacements.
