This has to be a pricing error doesn't it? It seems way to cheap for what these are. The next cheapest I've found is $190 at Leemings and according to Pricespy the cheapest they've ever been on sale for in NZ is $180.
Currently
$189.99 on sale at Noel Leeming
$219 on sale at JBHifi
$269 at Mighty Ape
$269 at Smith City
I have the previous version of this model, the 650's, and they're decent headphones. The 660's have USB-C, fast charging, adaptive noise cancelling, 2 point connection (connect to 2 different devices at once), hands free voice assistant access and other features you can read more about here https://www.harmanaudio.com/jbl/LIVE660NC-.html
Good deal I have the 400BT's and they've been great still look and work like new after 3 years
