The difference between the two:
Everything about the H1 chip has been improved on the W1 chip, and it also has new features.
The H1 supports Bluetooth 5.0(as opposed to Blue W1 Tooth 4.2), which means extended talk time (up to an hour). The H1's chip also offers twice the connection time when switching between Apple devices while listening to music.
Thanks to the H1 chip, the \"Hey Siri\" integration is finally on Apple Audio products. This feature provides a more immersive listening experience. With \"Hey Siri,\" you can change songs with your voice, adjust volume, and make calls without looking at the phone.
h1 is an upgraded version of w1, so it is improved in many aspects of performance. First of all, compared with w1 chip, h1 chip realizes the function of voice wake-up Siri voice assistant.
