** Update 6/15/2020 **Still love these headphones as much, if not more, than when I first got them. I use these exclusively for my now permanent work-at-home situation. I love how they can transition seamlessly from listening to Spotify via Bluetooth on my phone, to taking a Microsoft Teams call from my laptop. No need to change settings or switch anything over -- it all happens automatically as long as it's an approved connected device.---Was not sure about buying refurbished headphones, but didn't want to splurge the full price.Had I not known they were refurbished, I wouldn't have been able to tell. Not a single cosmetic scratch or scrape.Turned out to be a great purchase. I have three kids. Two under five years old, and I can attest that the noise cancelling is the perfect amount. Enough to block out the noise, but not so much as to block out the sound of screaming when my one-year-old bites my three-year-old and my assistance is needed with haste.These are incredibly comfortable. Not too heavy and perfect padding around the ears. I've worn for entire workdays on more than a few occasions now and they are wonderful.One of my favorite features is the easy and smooth transition between devices. I can be listening to music on my computer and then get a phone call on my phone and the transition is seamless, and then when I hang up from the call my Spotify kicks back in automatically.The charge is great. A full charge lasts about 18 hours, and I've seen no deterioration in this.The Bluetooth connection is solid. You can be about 25 feet away from your device and still get great audio.
