Hands-down you want the Plantronics BackBeat Pro 2. I have a set and they are EXCELLENT for precisely this purpose. I make a lot of phone calls for work (incidentally I am the product manager for most headphones at PB - but not the Plantronics brand) and usually prefer on-ear for calling as it's harder to control the volume of my voice without being able to hear it. The BBP2 has (average but nice to have) active noise cancellation with (fantastic) pass-through mics that amplify your voice while you're on a call, solving this. Plus they auto-mute when you take them off and auto-resume when you put them back on. Plus Class 1 Bluetooth for longer range. Plus AptX. Plus AptX Low Latency. Plus AAC. Plus 24 hours of usage per charge with IIRC 6 months of standby. Plus a nice lined storage bag. Incredible value for the dollars and comparable with significantly more expensive wireless headphones, you won't do any better than this unless you step up hundreds more dollars to Sony's (also fantastic) MDR-1000X/WH-1000XM2. I cannot recommend these enough.
