If you are in WA & want face to face I purchased from Value Hearing in Ardross. I will not say they are cheap but only because I don't think "anyone" in Aus is. I also just have a fundamental problem with H/A cost as a product in general when I just see them really as a mic,speakers, chip & software - certainly less sophisticated than a smartphone. BUT I guess miniaturisation costs a bomb.
I do think in comparison to their competitors in the Aussie market VH are better than most & worlds better than many. They did have prices readily available for a long time but after much fighting finally caved to threats of supplier blockaid if they didn't "toe" the line. I believe they will still happily give you a price list if asked.
I first went to a competitor with flash advertising & marketing spiel & was looking at $8k for their "recommendations" after a test at a desk in an office with an open window & all the ambient noise pollution including nearby traffic. I have a military background & knew that that level of audio testing was complete BS. So I went researching & came up with VH. They do a very thorough testing with a range of equipment including sound booth & styles of testing to not only test your basics but also your ability to compensate.
Bottom line is I ended up very happy, confident that I got good value (again speaking relatively in comparison to others not value per se) & a pair of aides that suited my needs to a tee for around $4k.
Don't get me wrong - I'm not saying VH are wonderful & the only trustworthy people around but they are worth including in your shortlist if doing some shopping around.
I also say again for a mini mic, speakers, computer chip & software the cost of them in general is just cringeworthy!
Oh PS - I perhaps should mention VH are in other states too now - I think Christo started in Perth but has expanded over time.
