1.0 out of 5 stars It's a great idea and the service was very good 24 Dec. 2015
By PhilP
Verified Purchase
It's a great idea and the service was very good; however, it's not useable for me. I have a Polycom VVX 410 and using the Headset Buddy there is an echo on the line at both ends which is very distracting. Disappointed as it's a great idea and would be a fantastic product but for that issue.

2.0 out of 5 stars Not for Polycom VVX series phones 27 May 2015
By Brian W - Published on Amazon.com
Verified Purchase
Probably not a bad product if it works with your phone, but did not work properly with any of our Polycom VVX phones (310, 410 or 500). The other caller would hear themselves talk, echoing back. As soon as I switched to speaker or the handset it went away and they could hear fine. Was using with a Panasonic 2.5mm headset that I've been using on our previous Polycom Soundpoint phones just fine. The VVX series was not on Headset Buddy's compatibility list or non-compatible list. Item used was 01-PH25-RJ9A. Was able to return for full refund.

1.0 out of 5 stars Poor quality! 27 Aug. 2015
By Shannon - Published on Amazon.com
Verified Purchase
Headset buddy, has no phone number on their website!!! The adapter I got did not work properly, it sounded like a bad cell reception and it had a dreadful echo that was a double echo. I could hear the other person's echo. I had Amazon ship me a replacement and it was just as bad. I will not use a headset buddy ever again, Claims they have a 100% guarantee, but no way to get in touch with them! I paid 10$ to have this shipped to my office to use for work, and the thing does not even work properly. I cannot describe my frustration and disappointment enough. Trying to talk on the new phone at work without a headset is giving me a crick in my neck and making me very grumpy. I need a head set adapter to use my headset so that I can do my job. I need it to have good quality so that the other person can hear me. The Amazon guy, could even hear the double echo and had a hard time hearing me, he said that he could hear himself better than he could hear me when I talked to him on the headset. I switched to the hand set and he was like, that is much better. So returned both adapters and ordered a audiocom one, and I am hoping that it works. Dont buy this piece of crap!

1.0 out of 5 stars NG in my Avaya / Nortel phone, maybe it will work in your phone 2 Jun. 2012
By darknology - Published on Amazon.com
Verified Purchase
This converter cable does not work on the Avaya (or Nortel) 1120E IP phone. Emails exchanged with Buddy Support (prompt and agreeable) not helpful; they suggest using a different headset and profess no knowledge of this phone. I then examined the wiring: The RJ9 side of this cable has only 3 conductors on it (pin 1 has no connection). Two of the four pins should be tied together to make a common for the ear circuit and the mic circuit. Buddy seems to assume that this would have been done in the phone itself. I'm sure Buddy works in some other phones but not this popular model. Could have bought a useful stack of toilet paper with the $16. Damn!
1.0 out of 5 stars Echo!!!!! 21 May 2015
By Amazon Customer - Published on Amazon.com
Verified Purchase
I really wanted this product to work with the headset I have for my cordless phone at home. I have the landline base (Panasonic KX-TG6671) in home office and bought this so that I can use the headset with the base. That way while on long conversations I wouldn't have to worry about having the cordless phone battery die on me etc. When I used this product it caused a lot of echo and everyone on the conference call could hear it. They said it sounded muffled and as if I was on speaker phone. Using the same headset on the cordless phone with the 2.5 mm port built in and that worked flawlessly. Unfortunately this product did not work for my setup and I had to return it.
1.0 out of 5 stars Great idea but... 9 Oct. 2016
By John L. - Published on Amazon.com
Verified Purchase
Great idea but did not work with phone as advertised. This item was purchased as it was listed for a specific brand of phone. However when used, the individual calling in had an echo of their own voice. It was tested from both land lines and cell phones from multiple locations and different headsets (Plantronics, Panasonic, Radio Shack) producing the same result. No echo was heard on the receiving end and communication was clear. I was hoping it was my answer.
