$259.99 for Sennheiser HD 600 Headphones

Amazon has the Sennheiser HD 600 Open-Back Headphones for $259.99, with free shipping.

This price is a slight drop from the previous deal at $272, with a notable savings of $140 from the original list price of $399.95. The current price still remains above the historically lowest prices, but it offers a better value compared to recent listings.

Given the original price of $399.95 and the current deal at $259.99, this is a solid discount of about 35%. The previous notable deal at $272 indicates that this is one of the best prices in recent memory, though not a record low.

This is a good deal for audiophile-grade, open-back headphones in the current market, and the price reduction is significant enough to recommend alerting users who are interested in high-end audio gear.
