They work great but I’ve replaced them with the new model. Significant wear on the head band but overall functions like new. The ear pads can be replaced for $15 on Amazon, I’ve replaced them a couple times once they show wear. Low and high settings for noise cancellation. Connects via Bluetooth and you can use the Bose app to control them as well. I can provide a cord that charges them. Lasts 15+ hours once fully charged.
