U.S posters may be interested by this post, which confirms that the new Costco Phillips aids only share the hardware of the Oticon OPN but not the open sound navigator or other features.
They say that the Phillips HA is very aggressively priced at $2500 a pair. However, the KS8 is much more aggressively priced at $1600 US a pair.
The KS8 has 48 channels, is that correct?
The KS8 is a super deal. Also, for the same $2500 the Philips Aid costs you can get the Costco Resound Preza, which shares the same technology as the Resound Quattro.
