The AirPods Professional 2 earbuds could also be value their asking value, as a collection of assessments carried out by musician and software program developer Stephen Coyle has indicated that the brand new H2 chip contained in the items affords important enhancements in Bluetooth sign latency.

Latency has all the time been a draw back of Bluetooth in addition to different wi-fi applied sciences and stands because the time between when a sound happens in your system and when that sound is then performed via your AirPods. This isn’t an issue for issues like video playback, the place the video might be delayed barely so as to make sure the audio is appropriately lined up.

Sadly, latency can change into a problem with what Coyle has beforehand known as “unpredictable” sounds, like notifications, sound results, keyboard clicks, audio modifying, and extra. The unique AirPods Professional supplied a big enchancment in latency efficiency in comparison with the unique AirPods, and the AirPods Professional 2 appear to have additional improved upon this.

Coyle used the next methodology to check the characteristic:

“I’ve stored largely the identical testing methodology as earlier than; I join AirPods to an iPad Professional, and faucet the display screen with an Apple Pencil. I take advantage of an audio recorder to seize the sound of the bodily faucets, and the ensuing audio, then measure the time between these sounds. One distinction from earlier assessments is that I’ve determined to measure solely keyboard click on latency.”

Per Coyle’s findings, the AirPods Professional 2 “carry out about 40ms higher than their predecessors, with a median latency of 126ms vs the unique’s 167ms.”

Coyle supplied the next further factors:

“Maybe a extra fascinating level to notice is that the second-generation AirPods Professional carry out solely 43ms worse than the built-in audio system (at 83ms). That implies that as much as two-thirds of the time between touching the display screen and listening to a noise happens earlier than Bluetooth knowledge leaves the system.”

Coyle concluded that he nonetheless believes there’s “an excessive amount of latency for audio suggestions to really feel snappy and responsive” with AirPods Professional 2. He acknowledged that it’s doable for additional enhancements to be made on the device-side versus the AirPods themselves.

Keep tuned for added particulars as they change into accessible.
