SINCODA 3 Pack RJ9 4P4C Male to 3.5mm Female Headset Phone MIC Audio Splitter Adapter Cable

It works as described but... I wanted to hook up a nice gaming headset to my landline for work. The volume is extremely low because the phone line does not have enough power to properly drive the headset. This is not an issue with the adapter but rather an issue with the whole system. I also tried buying an amp to boost this sound but it overloaded my phone line and the home phone would not turn on. If you're having trouble hearing then just buy a phone meant for the deaf and hard of hearing. They have volume controls that do what I wanted and aren't that expensive.

Great for combining a mic and headphone connection into one. However, I found that the picture labels on the plug (one for mic and one for headphone) were reversed, at least on the first three I purchased. I have yet to test the other three I bought.

Excellent

SINCODA 2 Pack RJ9 4P4C Male to 3.5mm Female Headset Phone MIC Audio Splitter Adapter Cablewas damaged 1 of the adapter cable was bend and broken where it was bend, the other adapter cable was smashed badly right under the hard plastic connection to the RJ9This package was badly abused before it got to me, beside taking a very long time to receive.I would like a replacement or refund

These work perfect for people who use a third party phone and wanna use a computer headset.

Fast delivery and excellent quality

This product did not work with my Cisco phone. I could hear the other party but they could not hear me.

Arrived fast. Was what was advertised.

When connecting to a berigner mixer, I'm receiving weird sounds. It should allow me to send the audio output to an input 1/4, RCA or XLR on a mixer. When connecting headphones or speakers it's ok. Also, sometime the sound quality is a bit altered when connecting a Mic for the third party we're talking with. It's working btw with a polycom phone that has RJ9 (Polycom IP335) or any other standard phones.

Very long delivery time but that may be partially due to mail strike happening at the same time. Once received microphone side of the cable does not work with the Corsair headset and standard rj9 phone jack. Very disappointing.

Just doesn't work at all with my phone. Maybe with other models?

Parfait pour l'utilisation que l'on en fait.

Good Product
