Was looking at best price for the Bluetooth version of this (PXC 550). While I came across this.
Keep in mind that PXC 550 is $399 at harvey norman so if you have AMEX offer it will be the same price.
Not much reviews for the wired version but having listened to both in store I seem to prefer the wired version in terms of sound quality (although they are meant to be exactly the same driver etc…) but the noise cancelling was slightly better on the PXC 550 with 2 modes.
Sennheiser PXC 550
With AMEX offer it will be cheapest to date for AU stock.
Either ask for $400 at cashier (they will happily do it).
Or price match with some shop that has this for around $370-380 and add a $30-20 item and use AMEX offer (plenty of memory cards or other small things that can be purchased).
PXC 550 has bluetooth and 2 ANC modes + APP, 30 hours wired battery life 20 hours bluetooth + touch controls
PXC 480 has 50 hours battery life. better wired design (the plug locks in place and is kind of hidden away) and to me sounds slightly better also can potentially last longer since less electronics in it (no bluetooth circuitry…)
The PXC-550 is $328 with the code PXC550 at Addicted to Audio.
