Its a review about this product
We have Cisco SPA525G phones with headset jacks. We purchased the "Plantronics 18straight Cable - Quick Disconnect To 2.5 Mm Plug" and then attached this headset to it. Worked great. Sound quality is good and microphone doesn't pickup a bunch of background noise. Only comment is that the cord from headset to disconnect is only 24 inches, so even with the 18" cable isn't long enough for a few of our users. consider distance.
