Question about Panasonic Rp-Tca430e-S

Good morning kuonilt5062, we operate the RP-TCA430E-S on a Gigaset cordless phone. The size of the jack (2.5mm) is important. Check which jack size (headset jack) your Offic 135Pro has. In general, we are satisfied with the RP-TCA430E-S, but sometimes it would be good if the volume could be turned up a notch (depending on the ambient noise). It's worth mentioning that the Panasonic RP-TCA430E-S was the only 2.5mm jack headset we found. I advise against using transition plugs. Thus, for us it was a test with a possible bad purchase - which fortunately did not happen.

Best regards, Th
