I have owned these now for 2 months.  I mow grass daily on average for 6 hours of continuous use each day on a 80 decibel riding mower.  I have a large head and these fit perfectly.  These will easily fit 90% of all human heads.  I have never run out of battery power in part because I gladly recharge them each night to ensure full battery power.  The bluetooth easily connected to my Samsung S7 edge phone and reconnects without issue after turning on for that day.  The microphone is the VERY BEST in class.  I tried 6 different Headphones (under $100) and all of the microphones were terrible at best.  With this headphone whenever I talk with a person thru my phone I can do so at full throttle on the mower, all 80 decibels and though I have not been on the other end of the line I have asked each person if they can hear me (I project my voice well) and all of them have said they could hear me clearly with only nominal background noise.  Exceptional performance.  I have my phone set up that if I receive a call whatever I am listening to is automatically paused.  After the call is terminated the thing i am listening to automatically restarts.  This works perfectly for Podcast Addict and Pandora apps.  A Bible reading app I use does not pause but the person on the other end cannot hear that reading.

The volume of sound to my ear is my only complaint.  If the person speaking whether live or on a podcast projects their voice I have no problems hearing.  But if the person speaking is a low talker or they cannot project their voice well it can be hard to hear what is being said.  For phone calls it has never been a problem.  My Bible app is pretty quiet.  Podcast addict and Pandora work perfectly fine.  I do wish that Honeywell would make the volume amplification louder so that I could choose to damage my eardrums if I want too. (I would sign a waiver if I had to).

An upgrade to this system (that I have not seen advertised and have no reason to believe that it will be implemented) would be to add Active Noise Cancelling.  I would pay another 30 bucks on top of the current features, for this feature if it were available.

Would definitely buy again and have highly recommended them to anyone that has asked me about them.
