Wireless headset perfect for concentration in the office. It has a high-performance noise-canceling function and was very useful for telework web conferences. I am selling it because I have improved my home audio environment and its usage has decreased. I was able to use it for web conferences of about an hour and a half even when I forgot to charge it, so I don't think there is extreme wear and tear, but please understand that the battery is a consumable item and there may be some capacity degradation. - Model name: Evolve 75 - Accessories: Charging dock - Case: Dedicated carrying case - Connection method: Wireless - Usage: For office and home use
