I bought a pair of Jaybird Freedom a few years back and this exactly is why I don't use them. I can't use them and have my phone in my pocket without them skipping. Indoors they are awesome, outside they are garbage.
Maybe the tech has advanced in the past few years, and I'll find out when I get a pair of Airpods. God bless that return policy.
Hasn't changed much. All these "geniuses" who give their personal experience as definitive proof (and we wonder why Trump is so close to the presidency).
Consider mechanism. If you turn on the microwave or if the WiFi router is being used at 2.4Ghz (802.11 b,g) between your mac and the headphones, say walking around the house you will notice considerable interference. Walls, depending on the material and thickness of your walls, could have a considerable effect.
It's like early Wi-Fi, a few people will have many problems but most will find it works so-so and a few will find it works well.
As for exercise bluetooth headphones, given the form factor the antenna would be more limited than over-ear headphones. The Jlab epic 2 are good value for the price, I tried the Bose, Jaybirds, and etc but price/battery/build-quality/etc Jlabs were my pick without trying the Sony offerings.
Over-ears like the Stance S1+, MDR-1000X, P7, and etc I'd be keen to try. The sound of the QC35s is quite poor and bluetooth range worse than the Jlab Epic 2 or the Beats Solo 2 wireless (sold these head clamps with bassy but poor sound) when I walk around the house using the mac as a source. Bose to me sound like beats without the bass and the main strength of Beats is the bass...
