I have been using this headset for work for over 3 years now and must say this is by far, one of the best headset I have used. They are comfortable and battery last long enough to finish all my meetings. I think there was only a few times it had ran out of batteries because I have meetings for 6 hours straight. Not only do they have a great product, I had a pleasant customer service experience. My company does not offer this specific model but rather a different model from Plantronics. However, I contacted Plantronics and they were willing to trade the model I received from my company for this model. I definitely recommend this product.
