Review on Enhanced Connectivity with GN1200 Smart Cord 6IN Coil Direct Connect - Part #l 88011-99 by Mike Burnett

I bought this because it is required for the Jabra GN2110 headset. Works, sound quality is good. I put a star because it's not plug and play and there's no easy way to tweak the settings - you just have to try all 10 settings and see for yourself which one offers the best sound quality. If you have the wrong setup, the audio can be good on your end and bad on the receiver line, dead on one or both ends of the line, or good quality on both ends of the line. If you're connecting a smart cable, I recommend calling another line to find out which output setting to use. I used my phone for a direct comparison and found that there is a big difference in speaker and headphone quality depending on how the key is set up. After tuning the button, the sound quality is excellent.
