66 Audio Pro Voice wireless headphones review: Alexa moves out of the smart home

If you liked the concept of ONvocal's OV Bluetooth headset, but skipped it because you didn't like the combination of in-ear headphones and a neckband, you'll want to check out 66 Audio's Pro Voice cans. These on-ear headphones host only Amazon's Alexa (the OV supported Alexa, Google Assistant, and Siri), but they're simpler to operate, far more comfortable to wear, and--most importantly--they sound better. The Pro Voice are clearly designed for audio performance first. They sound much better than you'd expect for their $140 price tag. The fact that you can use them to summon Alexa to do your bidding--be it controlling your smart home, reminding you of your day's appointments, or playing your daily flash briefing--is just the icing on a sweet sonic cake.
