I like that this product can connect to two devices at the same time. This feature seemed to work fine between my cell phone and my laptop. I was able to listen to music on my phone, and when I needed a headset to use Webex, it made the switch seamlessly. The problem I had was that when I was on the phone the person on the other end would say I sounded like I was underwater or having a sip of balls or food and the audio was spot on and constant was interrupted. The fit is also loose, and I had to constantly fidget to make sure it was comfortable. Not sure what "bone conduction" means, it's just bluetooth headphones. If you're looking for wireless headphones, this is fine. Just don't use them for calls.
