Uni4 Auxiliary Rj9 To Single 3.5Mm Smartphone Headset Adapter Cable For Cisco Ip Desk Phones (Black)

Amazing product for the price offered. It works perfect for my CISCO IP phone. Don't need to buy costly RJ9 headphones. I have neck pain problem and need to be on office calls continuously for hours. But now I don't need to hold the handset in awkward position and I can continue to work on my PC while being on the call.However, this adapter was not working for my another IP phone from Avaya. I contacted the seller and he promptly responded to address my issue. They are launching a new product that will work for Avaya as well. I'm eagerly waiting for that.Thanks Uni4 for the amazing service and being so courteous. Really happy! :)

It serves the purpose well, but the quality could have been a little better. There's too much noise on a slightest touch on it, and the voice echoes..But again, I think this all right for price.Update after a month:I find the noise issue not so critical, I can only feel the loud noise amplify while connecting/disconnecting and if moved too much, apart from that, the jack has been very helpful for me in all my meetings, upvoting it to 4 stars!!

Great product & great service.As soon as I placed order, I received call from seller to confirm my IP phone model. Seller confirmed that they will provide the cable compatible with my Yealink IP phone.Item was delivered timely by Amazon & and it works perfectly fine. Now no longer holding receiver for lengthy conference calls, as I can use headphones with my IP phone.

The converter cord looks fine and good quality. was easy to install. Worked fine for the voip phone 7940 model.i was able to use the adapter along with the mobile headphones for a clear conversation using voip phone.Worth the money since it makes the voip hands free and not dependent on speaker, there by maintaining privacy of the conversation. It is easy to switch from headphone mode to speaker mode using the Headphone button in the voip.

Had purchased this cable and worked for an weak only,later it stops working and all calls are coming noise only. Contacted amazon people also, amazon team told they cannot help and ask to directly contact seller.There is no way to contact seller and amazon team is saying that they cannot help, since don't have seller info. Such a big online shopping website saying that not able to contact seller and not able provide any information on the seller.

It works great while I have to listen to long duration calls without holding receiver and be hands free.But, my speech was not heard on the other side (muted). Had to switch to device speaker when I wanted to speak with my Cisco IP Phone Model No. CP-6921.

I have been looking for something like this for very long online and in offline stores. Finally found it on Amazon.This is a great product and makes taking long calls on office VoIP very convenient. My hands remain free to work on the desktop or take notes while the call is on. The build quality of the cable is good and it doesn't feel like either the 3.5 mm female jack or the RJ11 male plug is going to fall out of the cable.Thanks to the seller and Amazon to putting it online.

Great product especially for those who spend a lot of time on calls over an IP phone and are not at liberty to keep the calls on speaker. I used to use IP phone headsets earlier and had to carry multiple pair of headsets. Now with the RJ9 to 3.5 mm adaptor, I just need to carry my normal 3.5 mm headphones along with the adaptor which is less bulky.The adaptor is working well with my earphones on Cisco IP phone 7942. Voice and mic clarity is amazing.
