Pros Audio quality is okay.
Cons All kinds of cons. Product does not work as advertised. DO NOT BUY THIS UNIT.
Summary I have had to return this to the retailer once, and just got off the phone after arguing with Plantronics about a free shipper to warranty it for a second return.
The unit will not hold a charge. The first one would only hold a charge for 3 hours and I refunded/repurchased in 2 weeks. The second one has done okay but within 3 months the same thing has happened, it will not hold a charge. They are using totally JUNK batteries in these units. Go and look at the other reviews all over online before buying this, then DON'T BUY IT. It is not worth 5 dollars.
The on-off button is just WEIRD, you have to hold it down for 2 SECONDS ONLY or it won't shut off/turn on. If you hold it longer, it starts flashing thinking you are trying to resync it to the receiver. The initial (new) charge takes about 20 hours, not 10, and after fully charging it regularly over a couple months (or less), forget it, it doesn't work for more than 2 hours.
Pros Comfortable for long calls. Covers the ear to isolate you so you can focus on the call. Decent sound (inbound and outbound) for Skype. Moderate distance from USB transmitter (20 ft max). Long talk time.
Cons Mute is built into the boom mic by rotating it up. This causes a lot of noise to be transmitted while you rotate it up - a bad idea during a conference call. I never used it after a few complaints. And, that connection seems to wear out over time, caus
Summary I considered this top of the line when I purchased it. I wasn't disappointed. But, its function did degrade over time. I make skype conference calls all day long, so this has many 100's or even 1000's of hours of use. I didn't see any degradation in talk time. But, with headsets offering greater distance and sound quality, I'd keep searching if you are looking to use this for Skype calls.
