I've only had experience with one set of Walker's Quad and one behind-the-ear style hearing-aid HD (non-digital); no experience with Beretta's. The Quad's went south in a hurry, but the behind the ears are great. I've worn hearing-aids since I was 6 (31 years) and I can tell you the Walker's 'behind-the-ears' are worth their salt, both price and qualtiy. Only suggestion I would make, if you get the aforementioned style, have a molded ear piece made for overall comfort.
