SinLoon RJ9 Telephone Training Adapter Y Splitter RJ9 Headset Extension Cord Adapter 1 Male to 2 Female Connector for IP Phones (2 RJ9 FM)

We used this to install a second handset on our business phone, so we could use interpreters over the phone. We can now serve a larger client base.

Jack came damaged/apart so had to return it so cannot say anything more about it as never got to try it out

Didn’t realize phone had different size cords. Wasn’t able to use and Forgot to send back in time.

At this writing, there is only one other review, 1 star, stating that the RJ9 connector is wrongly sized. I ordered with confidence due to Amazon's Free Returns (no risk if it was junk) but was delighted that the device is exactly as described.Connection was tight and secure, properly sized for my RJ9 connectors. Perhaps the reviewer Espey received a defective product?Bottom Line: I'd buy it again.

This is a very small connector. Does not work with normal telephone or landline phones.

is ok

I have 2 different RJ9 telephone line and neither fit into this splitter, not sure if this item is defective but I'm highly disappointed and wouldn't recommend the product. One line was slightly too big and the other one fits inside but slides right out so wouldn't be much of any use.

Didn’t work. I put a meter on each connection and found the wire layout going in doesn’t match what came out. I have cut the wire and rewired correctly. Don’t buy this.

Bien reçu le colis merci

I guess it works I ordered by mistake

I missed the part that this is just used for hot desking headsets, as I assumed that the style of connector was universal.I will not return it as the cost of the return mail will be almost equal to the cost of the unit. I just hope that no one else will make the same mistake.The delivery was as advertised by Amazon...so no complaints there.

It worked!

it works. hard to find the old school stuff
