M22 Amplifier is FANTASTIC ! Review by Jeff
I needed a solution for my company phone instead of the traditional shoulder phone rest. I had a head set from a previous employer but it did not work with new employer's phone model. Locating the website was a snap with the phones model number. I was able to pinpoint the exact amplifier match for my phone and for my existing headset. The detail provided about the amplifier gave me confidence in my purchase and prepared me for what to expect in the operation of the amplifier and it's connection to my headset and phone.
Very pleased with everything - Thank you
Device works as expected Review by NWPa
We have had several of these in the office for years. They have proven to be very dependable and provide good sound quality to both users.
Very good piece Review by La Estrella
I bought the amplifier so that i can use a headset at work. I thought it was going to be hard to connect and use but it actually was very easy to install and the instructions were easy to follow.
Finally Working Review by David
I originally purchased my Plantronics headset with the the quick disconnect cable for my Aastra phone , but found that I couldn’t place my calls on mute. So after researching it further, I found I needed the M22 Vista Amplifier. After installing it my headset was finally working as expected.
good, basic unit Review by edwithasled
I first acquired the M22 unit several years ago, and it worked fine until a leaky battery (not a cheap one either) took it out. I checked other possibilities, but at least for hard-wired units this appeared to be the best. My new M22 works just like the old one, which is to say just fine. Useful volume control, easy install, and looks OK. Note: we lost another M22 to leaking battery. Even after careful cleaning and retouching a couple of solder joints, neither of the M22 units came back to life. So, check the battery conditions once in a while.
Great Product! Review by Margie
I was a little tiffed when I found out my Plantronics Starset headset could not plug directly into my new office telephone set. I needed to purchase an adapter. I didn't know which adapter so I called Headsets Direct and spoke to Wayne Baumgartner. Wayne told me I needed the Plantronics M22, I made the order over the phone. I received the adapter in a matter of a couple of days! This adapter is great. It was easy to set up, and even easier to use. I am now one happy camper. Thanks Wayne!

Plantronics M22 Amplifier Insider Info:
TECH REVIEW - When we demo any H-series headset, we always use the M22 Vista amplifier in lieu of a Direct Connect cable. The reason is an amplifier will be compatible with almost any phone, and it gives you complete volume control. Most phones have a speaker adjustment, but few, if any, have microphone volume control. With the M22 you control everything, so you and your caller hear each other perfectly. The M22 amplifier also uses a compatibility switch so it’s quick and easy to find a setting to make your system work. This is especially useful for users that travel and plug into multiple telephones. Have you ever had to interact with a co-worker and find yourself constantly trying to cover the mouthpiece of your handset? With the M22 amplifier, you have a mute button to take care of this problem, and it completely shuts off the microphone so you’ll have complete confidence your caller won’t hear your conversation. The M22 uses two AA batteries for power that will last for years. It’s also good to know that as the batteries become weak, you will hear beeps in your headset to indicate a battery change is needed. You’ll have days, if not weeks, to replace the batteries and will only notice a slight decrease in quality.
HOW TO INSTALL - When using the M22 amplifier on older phones, you will plug the telephone cable (or pig-tail cable) into where your handset plugs into your phone. This typically means you will remove the handset from your phone to use your headset, and place the handset back in the cradle to hang up calls. On newer phones with a headset port, you will use this port and typically push the ringing line or a headset button to initiate and terminate calls. Install 2 AA batteries in the side compartment (+ facing outward on the top battery and - facing outward on the bottom battery) and slide the battery cover into place. Next start with the compatibility switch (located on the side) on setting 5, which is the most universal. Plug your headset into the M22’s coiled cable at the Quick Disconnect connection and lift your handset (on older phones) or press an available line on newer phones. You should have a dial tone. If not, slide the compatibility switch to the other numbers labeled 1-6, using the white pick tool located on the bottom of the M22 amplifier, until you have a dial tone. Once you have a dial tone, call a co-worker and adjust your microphone volume. Once the compatibility switch and microphone volume settings are complete, slide the included cover over them to ensure they’re not accidentally changed. You are now set for years of use with your Plantronics M22 Vista amplifier.
HOW TO CLEAN - When cleaning your Plantronics M22 amplifier, always use non-alcohol chemicals or wipes. Using alcohol-based products over time will break down the cords making them very stiff and clumsy to use. You will want to wipe all plastic components and cables, but avoid saturating any openings where electronic components are in close proximity. For the M22 amplifier, this will include around the speaker volume dial and other buttons located on the top of the amplifier. An old toothbrush works very well to clean dust build up from the groves in the casing. When cleaning your M22 amplifier, also avoid sticking anything into the end of the Quick-Disconnect connection where the four metal contacts are located. This connection is made to last, and more damage than good will come if you try to clean it.
WHO USES THIS MODEL - The M22 amplifier is used by business professionals that require the best possible audio sound quality. It’s compatible with most phones, making your life much easier, versus using a Direct Connect cable, which requires determining compatibility and then hoping the volumes are adequate.
