As far as these protecting your hearing, being able to talk and hear conversations with ease, and comfortability, these get an A+. The app for these on the other hand well, that worked for me once and that hasn't sync up to the headset again. Researching online I've found this seems to be a common issue with the 2.0's with no known fix as of yet. I didn't really purchase them so I could talk on my phone or listen to music, so I still really like them. It would be nice though if they worked as they were supposed to with the app. I use these regularly while shooting and being an RO at centerfire long range shoots and they have been comfortable to wear all day.
