Question about Jabra Evolve2 75 Duo MS

The difference to the Jabra Evolve2 65 is not only the active noise cancellation (ANC). The Evolve2 75 has 8 microphones (4 digital, 4 analogue) for better voice quality and ANC, while the Evolve2 65 only has 3 digital microphones. The Evolve2 75 also offers customisable Advanced ANC with 11 levels and the HearThrough function, which is missing from the Evolve2 65. Both have the same 40 mm speakers, but the Evolve2 75 has a shorter microphone boom and a significantly longer battery life of up to 36 hours. The Evolve2 75 is also only available as a stereo version, while the Evolve2 65 is also available as a mono version.
