Newegg Flash currently has these headphones on sale for $149.99, shipped. These might be a decent alternative for people who don’t want to spend the $225+ on the Sony WH-1000XM3 phones. According to the Camel, lowest price on Amazon was $180.
Here’s a review ; their biggest complaint appears to be the price ($400 MSRP). I suspect at this price it would be more favorable.
