AV205: manual-tweaking ease-of-use
Thus far, the AV205 has proven to be a significant improvement to my Mom's ability to comprehend dialog. While I like the ability to individually change all the settings, we've found that for my Mom's particular hearing and for most of the content we play through the AV205's speakers - we don't change center-channel emphasis (we use: "FOC"=3 & "Sd"=1), frequency-range companding (we use: "CPS"=3 & "OL"=on). The settings we do change are: the amount of synthetic harmonic content applied to formants ("ICE" setting), bolstering of the 4,500Hz band ("FCP"), amount of cutoff of sub 500Hz frequencies, and volume. In fact, I have to incrementally change ICE, FCP, bAS, and Volume for everything we watch. The only improvement I can think of making would be to further simplify the "end user" remote control to only have: Mute, Vol Up/Dwn, ICE 1-4, FCP 1-3, bAS 1-3 buttons - but that reflects my Mom's particular needs of course.
Super Useful for vocals but cuts out occasionally
Use mostly for TV and video/film, primarily for vocals. Good, very very clear with vocals, can hear well TV voices, but connection to computer (Mac mini) cuts out now and then even though battery close to full and only air between headphones and CPU unit. With computer, volume even at maximum on low side but can hear it clearly enough. A vast improvement over just TV alone and other headphones turning up volume means music louder than dialog. Would definitely recommend these for very good relative improvement on vocals. My neighbors certainly appreciate it as my TV volume is much lower! Note: I have ZVOX bar for my Samsung smart TV so music etc. very controllable on bass vs. treble, compression, vocals, etc. But these do not depend on that, bluetooth connection is straight to TV only.
