Comsoon J22: This adapter also landed in the top three in our most recent round of testing, and it was close to being our runner-up pick—until Brent measured its performance. We liked its solid Bluetooth signal, long 17.75-hour battery life, more stylish design, and verbal cues to indicate when a device is connected or disconnected. We did not like the fact that the side panel had one long, connected button for +/- instead of separate buttons, and that the functions were reversed: Track skip was a short press, and volume was a long press, which felt less intuitive to us (though some people may prefer it). We especially disliked the measurements: This device produced only 2 mW of power output, and the latency averaged 190 ms but was unstable and jumped from 90 to 260 ms. We saw those results play out in our real-world test, too, as one day we could see obvious lip-sync issues when watching video on our phone, and the next day we couldn’t. Plus, the microphone, while louder than the others, delivered a harsh, digital sound.
