The Sony MDR-1000X headphones (ANC and BT) go for $350 in new condition at authorized Sony dealers, but if you want to save a significant amount while still get some warranty, you can get them in certified refurbished condition with a 90-day warranty from Secondipity through Amazon for $230 with free shipping in your choice of Beige MDR-1000X or Black MDR-1000X. The black is fulfilled by Amazon, so it is Prime eligible, but has a limit of up to five units per customer.

Speaking of Sony, in addition to the previously mentioned Sony sales, their XB10 Portable Wireless Speaker with Bluetooth (2017 model) are on sale for $38 each, in three different color schemes.
