Summary: I brought these for use with Dragon naturally speaking and they are working very well. Possibly the noise cancelling is helping with the accuracy, possibly not. All I can say is that for the price, these are working, they are light on the head (no unreasonable tension between the ear cups) and you could easily forget that you have got them one if it wasn't for the use I'm using them for.
Summary: I use these with my dragon NaturallySpeaking software. The pair that came with the software were absolutely awful. I saw these on Amazon at a very good price. Plugged them in and we were off. I like the fact they have a separate volume control and a very easy on off switch, which is very useful if you are dictating and somebody arrives, you don't have to scrabble back to the main machine to turn it on or off. They have good adjustment to ensure good fit .
Summary: I use a number of different applications to keep in touch with my colleagues across the world and travel relatively frequently and so needed a headset that would provide excellent sound quality, but also be durable so it wouldn't break after 6 months. I've had headsets around this price point before which haven't lasted either through poor sound quality or pieces "fall off" after a while.
Summary: Bought these because my sons laptop does not have an external microphone input jack. He uses them for Skype / Minecraft "team chat" etc. Very easy to configure, true "plug and play" with Windows 8. Good quality audio.
Summary: I use it for Skype calls, mostly Skype to mobile, so far so good. The call quality is fantastic, literally no complaints. I also bought it to cancel out some exterior noise and it seems to be doing the job. Highly recommend.
Summary: The PC8 headset is a decent quality headset, for both audio and the microphone. The biggest issue with it is the microphone quality is regularly dropping during use, causing distorted sound so that others cannot understand what you are saying. Could be a faulty unit, but the problems started directly outside of warranty. Would not recommend.
Summary: This headset works really well. I use them when I am teaching on-line and wear them from 8:30 am through till 5:30 pm (or sometimes a little later) and they are just so comfortable. The sound quality, both hearing and speaking, is tremendous and I have not had any adverse comments from my on-line students regarding mike drop-out or excess noise. They work really well and, like the header states, theyre - effective and comfortable.
