Thomas M. ★★★★★

Finally, an adapter that actually works with my office phone's RJ9 port without any static. The 3.5mm female connection feels solid, and it let me swap out the cheap bundled headset for my own.

Ellie ★★★★★

I was tired of being stuck with the cheap headset that came with my office phone. This little adapter lets me plug in my own comfy 3.5mm headset, and the connection is solid with no static.

Andrew ★★★★★

Finally my call center headset works with my desk phone instead of collecting dust in a drawer. The RJ9 connector clicks in firmly and the 3.5mm female jack is snug enough that the cord doesn’t wiggle loose during long calls.
