Using "11 -inch iPad Pro (3rd generation)" (2021 model), verify that wireless earphones cannot be used with delay!
Many people use iPads as video viewing and game consoles.For gamers and video viewing people, the voice delay that shifts the timing of video and sound is a point that bothering the head.It is often said that wired earphones are recommended because the voice misalignment occurs in Bluetooth wireless earphones, but if you look at the latest iPad series, you can see the iPad Pro, the iPad mini and 3 iPad mini except for MUPAD..There is no 5mm earphone jack.[See all photos] So I tried various patterns using my "11 -inch iPad Pro (3rd generation)" (2021 model).・ Adapter that can be converted from USB Type-C to earphone jack ... Anker "USB-C & 3.5mm audio adapter (actual price: 1490 yen) ・ USB Type-C terminal wired earphone… Audio technica “ATH-CKD3C” (actual price: 3080 yen) ・ Completely wireless earphone that supports “low delay game mode” ... Soundpeats"AIR3" (actual price: 4570 yen) In addition, I will also try "AirPods Pro", a built -in speaker of the iPad as a comparison target.
Verification of the delay of AirPods Pro
Voice delay called audio latency is a deep -rooted problem.There are some parts that are due to wireless and audio output delays, and there are parts that come from the buffer of the system and application, and there is voice delay even with built -in iPad.So I actually measured the video and voice gap in YouTube videos and games.Since the number of delays is used to use milliseconds (MS), for example, 0 ms is 0..It's one second late.First, what I tested was a comparison of delays using videos using YouTube.Several videos for delay tests have been released, but this time Razer famous for gaming devices "Razer HammerHead True Wireless Earbuds | Audio Latency Test" (https: // Youtu.Verified with be/zpaj3sruhlu).If you pause at the moment the sound comes out, you can test a voice delay.The photo of YouTube players is a reference value because the sound does not stop accurately, but if you repeat the same test dozens of times, the difference between the devices will be seen.▼ Delay of speakers with built -in iPad… Approximately 31ms (0).031 seconds) ・ AIRPODS Pro delay ... Approximately 81ms (0).081 seconds) ・ The delay of USB earphone jack conversion using anker adapter… Approximately 31ms (0).031 seconds) ・ Delay of USB earphones of audio technica ... about 31ms (0).031 seconds) ・ Non -game mode of Soundpeats "Air3" ... Approximately 69ms (0).069 seconds) ・ Game mode of Soundpeats "Air3"… Approximately 31ms (0).031 seconds) Built-in iPad, USB earphone jack conversion, Type-C earphone, wireless game mode (0).031 seconds).It is the limit of this measurement method that the numbers are perfectly aligned here.Wireless non -game mode is about 69ms (0).069 seconds) By the way, AirPods Pro is about 81ms (0).081 seconds) was the most delayed.Based on the results of this Youtube delay test, how much of a general video is worried about the delay?Approximately 81ms of the largest AirPods Pro (0).Even if you watch YouTube's Japanese news program in 081 seconds), you can hardly understand the gaps in the movement of the mouth.For video viewing, you don't have to worry if you don't have a very delayed earphone.
