H1n can overdub, the recording level can be adjusted by a rotary wheel, can be connected to iOS devices, output a level tone,.... The new one is optimised for musicians, poscasters, filmmakers, the old H1 is a simple recording device with the option to serve as a USB mic on the computer.

Hello Stokasmud

You can see the difference between the two products mentioned here: https://www.digitec.ch/de...
The only differences are the sampling rate (96kHz vs. 44.10kHz) and the battery size (AAA vs. AA).

I do not take any responsibility/liability
