Review on ๐ 5-Pack RJ9 Coupler Connector Extender: Connect Two Handset Cables Cord Together 4P4C / RJ9 /RJ10 /RJ22 Effortlessly by Olivia Turner
Poor quality 4 out of 5 in package
I bought these to extend my phone headset. In the first, I connected each line and tried to make a call. The connection quality deteriorated and any movement of the wire in the coupler connection caused strong static electricity. I tried the remaining 4 ports and only one works with decent call quality and no static electricity when touching the port or handset jacks.
