Sony makes great active-noise cancellation (ANC) headphones, and the WH-1000XM3 is its best pair yet. Once in a while, and for brief periods of time, it's come down in price to about $300. Most of the time, however, it usually sells for $350. The same eBay seller we covered earlier in June is back to selling refurbished units for just $200, a full $150 off full price.
