Since only one combo jack for headsets is available on my Lenovo laptop, I needed this adapter. Unfortunately, the headset manufacturer delivered this not with. I bought the adapter in August 2012 and it was delivered a decent part. The adapter really makes a good impression. The cables are all firmly. A first functional test was positive. The sound is good. Previously, I had my headset always at the dock and I always had a hum and noise in my recordings on it. Alternatively, I've always put the mic just in the combo jack and then always had to pull the plug in the sound reproduction. Of course that was not practical. All the more I was glad to find this adapter in the network. The price is ok
So who wants to operate his headset on a combo jack, should strike here. On a Lenovo Thinkpad T410 is still working properly.
