Rated 5 out of 5 by from HeadsetBought for Ring Central product, sound quality and microphone are perfect just like a handset. Great price also. Don't need $100 plus headset to do the job

Rated 5 out of 5 by from Ok sound, w/sensitive microphone - when it works.Was issued one of these to use at work with Skype for Business.The microphone kept indicating that it wasn't working. People would NOT hear my voice until I clicked the toggle switch for the microphone off & on.I would NOT recommend purchasing one of these, EVER.

Rated 5 out of 5 by from Very effectiveI had tried another headset through Nuance but it never was able to translate my voice into Dragon for Mac. Your product worked perfectly right out of the box.

Rated 5 out of 5 by from Skip the 300s and go for 200s or 600sWe ordered the 300s when our supplier was unable to obtain additional C-210M. They are horrible, they pick up back ground noise from the office and are hard to hear on. The 200s and 600s we have are a much better quality and have not had any of the problems with them that we've had with the 300s. We had to send the whole lot back because of the issue, and we tested more than one to make sure that it wasn't an issue of getting one that was defective.

Rated 5 out of 5 by from Distracting, unimpressive, minimally sufficientSetup is simple, plug it in and everything is working.  The audio quality is ok.  Volume is low, my ancient headphones have better sound, and when the microphone is on, if my breathing isn't silent I can hear it.The biggest problem is the mute notification that cannot be disabled.  Every 15 minutes, there is a loud beep (louder than anything I'm listening to reminding me that my microphone is muted.  It is totally unnecessary (there is a red light on the unit showing mute, an icon in my application showing I'm muted, a light on my laptop showing I'm muted, and I'm no longer able to hear my own breathing) and extremely distracting when I'm in a conference call.After multiple calls to support, I have determined that Plantronics considers this problem to be a feature, and provides no way to disable it.  The Spokes software will recognize the headset, but there are no device settings for it.  Until this is corrected, I highly recommend choosing a different headset.

Rated 5 out of 5 by from Great Sound - headache after 10 min on bold headsI like the product sound quality, but the headband, that after a few minutes touches my bold head cuts into the skinn more and more, so that after 10 minutes I get a 5mm deep notch and real headache. So sorry. But I will add some wider headband support with cardboard, and see if this makes it better.

Rated 5 out of 5 by from Cable tanglesThe cable keeps on tangling, otherwise the product is good. The foam covers have disintegrated long ago though.
