Using Advance72 (made by Sonova) has BlueTooth which makes using a phone a breeze. The Hearing Remote app allows me to override the audiologist configured settings for volume, listening modes and equalizer.

IMHO rechargeable models are not worth the extra cost. With a typical 5 year replacement cycle the batteries will no longer hold the early levels of charge. 312 batteries are cheap and easy to carry spares.
