Rob,
I don't think there is much to decide except between these two:
We have used the older EarTec ‘marriage saver’ model for 8 years (with a single ear headpiece and hard-wired radio module, which we wear around our necks in a Velcro pouch). Their new model is a nice all in one headset.
You want ‘full duplex’ meaning you can both talk at the same time, like a cell phone (not like a VHF or Family radio push to talk radio where one person is talking and ‘stepping on’ the talk of the other). You want hands-free with no buttons to push once both units are powered up. You want only ONE ear to be covered, so you can hear your VHF, other deckhands etc talking with the other ear. You want both your hearing aids in (this I never do on the boat, the little buggers are too expensive to be falling into salt water).

There are some Bluetooth cellphone headsets for motorcycles etc that you might research, but make sure you meet the above criteria to make it work well. They all cover both ears and Bluetooth range is only about 30 feet. You want to hear her in the parking lot when you’re on the boat.
At 8 years, we figure our EarTecs have way more than paid for themselves. Although I never expect over 4 years from any rechargeable battery, these are still good for 4 hours min (and can be replaced).
There is an article in one of our throw-away boating mags on this with the same conclusions as Panbo.
Best of luck on your search, and let us know what you find that best meets your needs.
See ya on the water! (Hearing you is a different issue).
