cAoku Telephone Cord Detangler Header 360 Degree Landline Swivel Cord Anti-Tangle Blackwhite Telephone Accessory (4pcs, Black)

I purchased these for my office phones. 1 didn’t fit into the phone, 1 made the line crackle every time it moved, 1 worked the way I hoped it would. When trying to remove the crackling 1 it broke off into the phone, I had to use tweezers to get it out. I’ve decided to not try a replacement.

Work fine!

Great, they work perfectly, should have gotten them sooner

poor quality - won't stay plugged
